Fears mount that World Surf League has pushed equality too far … – BeachGrit

It isnt over yetthere could be consequences later

The name may not ring any bells if youve come into surfing late, but tour surfer Roy Powers, who was active in the early two thousands, sure knew how to steer a surfboard, winning at Haleiwa (beating Joel Parkinson) and Steamer Lane.

In 2007, ESPN ran a glittery profile on the kid.

He is quick to smile, just as quick to laugh; the sort of engaging, good-humored optimist given to saying such things as, All those pissed-off terrorists? They have to laugh too, dont they?

And Powers has reason to laugh. As a top professional surfer he has sponsorship deals that pay him well into six figures. He has a travel fund that covers his trips to surfing contests all over the world, including Australia, Tahiti, France and South America. He owns a home about a mile from here plus a house on the Big Island hes never seen. He recently fulfilled a lifelong dream by winning the Reef Hawaiian Pro competition, guaranteeing himself a spot on the World Championship Tour next season. And on this beautiful December day, he golfed in the morning, will surf a bit in the afternoon and has prime tickets for the next evenings Hawaii Warriors football game with his father. He is 26, tan, lean, muscled and has never had to worry about his weight.

If you really want to appreciate how large Powers lives, consider this story he tells. When he finally secured a date with a girl he had a crush on for years, he took her to a strip club in Honolulu, where he gave her 500 $1 bills and had her make it rain. Its not classy, he says, but it worked.

But while his career mightve ended up a little lacklustre, Powers was a close friend of Andy Irons and drifted off the tour after his pals death in 2010, what was happening behind the scenes sure wasnt dull.

In an extraordinarily candid interview with the The QuiverCasts Mike Steele, Powers, now forty-two, tells of a double life as a pro surfer and a drug dealer, working in a dark world where drug kingpins offered to kneecap his competitors and who wouldnt think twice, says Powers, about blowing your car up with you in it.

Thing is, says Powers, where theres excitement happening, ie at a surf contest, theres drugs and the way those things get there is by criminals and gangsters and organised crime. Its everywhere.

Powers is forced to talk in generalisations, naturally, like, whats he gonna do, name names, but the candour is wild.

The real fuckers that are collectng the big money, theyre mellow, normal people, mellow guys they dont commit petty crime, they dont get involve bed in bullshit they smile at you and shake your hand, but they dont have a problem with blowing your car up with you in it

I saw some things thatfuckI followed orders.

The last years on tour I wasnt really into it, especially the year after Andy died. Im really going to the dark side, but Im thriving in that I got a lot of respect. I was able to build connections to help people I knew who really wanted to be that worldfor people to get certain thingsa level of quantity or quality they could never get. I was in that position and had done business and spread blood for them.

I was doing some of the product. It fucks with your mind. Anybody who says you can control things, you cant brother. The shit grabs ahold of you. If youre around heavy negative things, youre going to start thinking heavy psychotic things.

Being locked in a cage and realising you have no choice of what youre doing, if you can eat, whats going to happen in the next ten seconds. That really hit me but it was also refreshing. I was out of that world. I would hit the restart button.

(In prison) everyones starving, everyones trying not to get stabbed, theres the gang politics, the predators every single moment of the day. Being a white guy in a Hawaiian prison system is fucked. Youre a minority but I knew how to operate. The gang I was operating with inside was top notch. We were like a military unit in there.

Fred Pattachia wrote me a letter. It hit me so hard. His passionate words from twenty-five years of friendship. He cared! I read it all the time.

Ive done some heavy heavy shit.

It isnt over yet. There could be consequences later.

Gets real good around the thirty-six minute mark.

Title: EDIT-301 Shows Promising Preliminary Safety and Efficacy Results in the Phase I/II Clinical Trial (RUBY) of Patients with Severe Sickle Cell Disease Using Highly Specific and Efficient AsCas12a EnzymePresenting Author: Rabi Hanna, M.D., Department of Pediatric Hematology Oncology and Blood and Marrow Transplantation, Cleveland Clinic Childrens, Cleveland, OH, United StatesDate/Time: Saturday, June 10, 2023, 4:30 5:45 p.m. CEST/ 10:30 11:45 a.m. EDTLocation: Harmonie 1, Messe FrankfurtSession: s437 Gene therapy and cellular immunotherapy Clinical

Story continues

EDIT-301 is currently being investigated in a clinical study in patients with severe sickle cell disease (RUBY trial, NCT04853576) and transfusion-dependent beta thalassemia (EDITHAL trial, NCT05444894). In addition to the clinical data update from the RUBY trial at EHA and in a Company-sponsored webinar next month, the Company will present a further clinical update from the RUBY trial by year-end. Additionally, the Company is on-track to dose 20 patients in the RUBY trial by year-end.

About Sickle Cell DiseaseSickle cell disease is an inherited blood disorder caused by a mutation in the beta-globin gene that leads to polymerization of the sickle hemoglobin (HbS). In sickle cell disease, the red blood cells are misshapen in a sickle shape instead of a typical disc shape. The abnormal shape causes the red blood cells to have shortened lifespan and to block blood flow causing anemia, pain crises, organ failure, and early death. There are an estimated 100,000 people in the United States currently living with sickle cell disease. Higher levels of fetal hemoglobin (HbF) inhibit HbS polymerization, thus reducing the manifestation of sickling.

About EDIT-301EDIT-301 is an experimental cell therapy medicine under investigation for the treatment of severe sickle cell disease (SCD) and transfusion-dependent beta thalassemia (TDT). EDIT-301 consists of patient-derived CD34+ hematopoietic stem and progenitor cells edited at the gamma globin gene (HBG1 and HBG2) promoters, where naturally occurring fetal hemoglobin (HbF) inducing mutations reside, by a highly specific and efficient proprietary engineered AsCas12a nuclease. Red blood cells derived from EDIT-301 CD34+ cells demonstrate a sustained increase in fetal hemoglobin production, which has the potential to provide a one-time, durable treatment benefit for people living with severe SCD and TDT.

About RUBYThe RUBY trial is a single-arm, open-label, multi-center Phase 1/2 study designed to assess the safety and efficacy of EDIT-301 in patients with severe sickle cell disease. Enrolled patients will receive a single administration of EDIT-301. Additional details are available onwww.clinicaltrials.gov(NCT04853576).

CAR Technology in Cancer Therapy: From CAR-T to CAR-NK – The Scientist

One-Stop Research Support for CAR-NK Therapy

Sino Biological

Cell-based immunotherapy is a targeted approach to cancer treatment that continues to evolve beyond its early successes treating leukemia. Researchers employ new technologies, such as chimeric antigen receptors (CARs) expressed on the immune cell surface, to effectively target hematological malignancies and solid tumors with cell therapy.1,2

To develop CARs, scientists engineer hybrid molecules made of T cell receptors and antibody fragments. These receptors direct immune cells to recognize and destroy cancer cells that express a specific antigen targeted by the CAR antibody domain. In recent years, scientists fine tuned CAR therapies for improved safety and efficacy. Optimized CAR molecules have high target antigen specificity, enable efficient immune cell activation, and cause minimal off-target effects.3,4

Once an optimal CAR is developed, researchers use reliable lentiviral packaging methods to transfer it to immune cells for CAR expression and quality control experiments such as immunoassays and cell viability assays. CAR-T therapies, T cells equipped with CAR expression, continue to lead the way in cell-based therapeutics. Therefore, researchers must design CAR molecules in ways that ensure the durability and persistence of CAR-expressing immune cells in the body.2-6

For CAR-T cell therapy, researchers genetically engineer T cells derived from either a patient or a donor, modify them to express CARs, expand the cells ex vivo, and infuse them into a patients bloodstream. Since 2017, over 700 CAR-T therapy clinical trials have been registered and the FDA has approved six CAR-T therapies for the treating hematological malignancies, including leukemia, lymphoma, and multiple myeloma.1 However, despite their clinical significance, there are limitations to producing and employing CAR-T therapies. Collecting T cells from a patient or donor is costly and time-consuming, especially for patients with compromised immune systems. Additionally, CAR-T cell therapy may cause severe side effects such as cytokine release syndrome (CRS) or neurotoxicity. Finally, CAR-T cells struggle to penetrate the tumor microenvironment (TME), which can hinder their therapeutic function.3,4

To overcome conventional CAR-T limitations, researchers turn to promising new CAR strategies. In multi-target CAR-T, scientists design CARs that recognize two or more antigens per receptor, resulting in broader immune coverage. Another new avenue involves alternative immune cell types such as natural killer (NK)-based cell therapies. Part of the innate immune response, NK cells can eliminate abnormal cells, including tumor cells and virally-infected cells. Researchers produce CAR-NK cell therapies with the same receptor-antigen hybrid technology as CAR-T, but express the CAR in NK cells. Scientists can derive NK cells from a variety of sources, including umbilical cord blood (UCB), peripheral blood (PB), human-induced pluripotent stem cells, human embryonic stem cells, hematopoietic stem cells, and NK cell lines. In comparison to CAR-T therapy, CAR-NK cell therapy is safer with a lower chance of negative immune side effects, more efficient antitumor activity, and higher efficiency for off-the-shelf production. CAR-NK cell therapies for solid tumors and hematological malignancies have shown promising results in clinical trials.1,3,6,7

Comprehensive Solutions for CAR-T Therapy

Sino Biological

Before cell therapies reach the clinic, scientists develop them through a multistep process. Whether the therapy is CAR-T or CAR-NK, researchers must collect immune cells, employ genetic engineering to create a targeted CAR, transduce immune cells for CAR expression, culture and expand the CAR-expressing cells, and test for quality control.

As a global leading supplier of bioreagents and CRO services for the biopharmaceutical field, Sino Biological provides comprehensive solutions for scientists developing CAR-T and CAR-NK cell therapies.5,6 These solutions cover each step from CAR development to CAR-T and CAR-NK cell preparation and cell quality control. Sino Biologicals reagents and services can support researchers during each stage of cell therapy development from early target discovery to preclinical phase.

What’s Exosome Therapy And How Can It Help Your Skin & Hair? – Glam

As you age, your skin's collagen production isn't the only thing that slows down. Your hair follicles do, too, with some growing out considerably thinner hair and others ending the hair growth cycle altogether. In addition, sebum production also reduces as you age, leading to duller, lustreless hair.The drop in hair growth and thickness eventually leads to permanent hair loss. But of course, there are other causative factors of hair loss, such as genetics, medications, and stress.

When fed into the follicles and scalp, exosomes reawaken the follicular cells, jumpstarting them and fostering hair growth. The therapy also helps prolong the anagen phase of the hair growth cycle and decrease or delay the catagen phase. Anagen is the growth phase, while catagen is the phase where hair growth stops. By prolonging the anagen phase, the follicles have more time to produce hair and combat hair loss. With their wound-healing and anti-inflammatory properties, exosomes can also help repair damaged tissues and follicles in the scalp. And everyone knows that healthy follicles equal healthy strands.

You can have more than one exosome session to reap the full benefits. However, waiting 3 to 6 months between sessions is preferred to evaluate if more sessions are necessary.Now that you know the benefits of exosome therapy for your skin and hair, we're sure you're wondering about the procedure. Well, here's what you need to know pre- and post-procedure.

Thalassemia gene therapy approval marks a new era of treatment – Labiotech.eu

A newly-approved gene therapy is transforming the lives of patients with beta thalassemia an inherited blood disorder by helping to stop or significantly reduce their reliance on blood transfusions, says an expert from a leading global health system, Cleveland Clinic, on International Thalassemia Day on May 8.

A gene therapy known as betibeglogene autotemcel, or beti-cel, was approved in August last year by the US Food and Drug Administration (FDA) as safe and efficacious for adult and pediatric patients with transfusion-dependent beta thalassemia.

Rabi Hanna, a pediatric hematologist-oncologist at Cleveland Clinic Childrens which is in the process of becoming one of the few centers in the world certified to offer the gene therapy said: This is a milestone in thalassemia treatment as gene therapy uses patients own hematopoietic stem cells to produce healthier red blood cells and cure their blood disorder or at the very least, significantly reduce the number of blood transfusions needed to manage their condition. Thanks to gene therapy, we can remove the challenges that thalassemia patients face and give them the potential to pursue their goals and dreams without the restriction of blood transfusion or complications of iron overload.

Thalassemia, which has two types alpha and beta is among the most common genetic disorders and occurs most frequently in people from the Middle East, Mediterranean countries, North Africa, India, Central Asia, and Southeast Asia.

Beta thalassemia affects the bodys ability to produce hemoglobin, a protein in red blood cells that allows them to transport oxygen throughout the body. Individuals diagnosed with beta thalassemia major develop serious symptoms at a young age, which can be treated with frequent blood transfusions, but the transfusions themselves create the risk of iron overload with the potential to damage patients liver, heart, and endocrine system.

The new gene therapy, which resolves this problem, is ideal for teenagers or slightly older patients who have already started to experience complications from blood transfusions, Hanna said.

Hanna said: The gene therapy includes a short period (four days) of a chemotherapy called busulfan that may impact on male and female patients fertility, so it is better to wait until patients reach their teenage years so that they can undergo fertility-preservation treatment, although we do have methods to preserve fertility even in pre-pubescent patients. On the other hand, it is best not to leave it too long as after years of infusions, patients hearts and livers may have already been severely impaired from iron overload. Generally, the healthier the patients are at the start of the gene therapy process, the fewer side effects they will have.

The minimally invasive beti-cel treatment is delivered in three phases over several months, Hanna said. In the first phase, two medications (G-CSF and plerixafor) are used to stimulate the patients bone marrow to produce more stem cells. In the second, blood is drawn for stem cell collection from peripheral blood, and these stem cells are sent to the treatment company to perform the gene modification, that is, inserting a gene that enables them to produce non-affected hemoglobin. The modification process takes around two months.

The final phase takes place in a hospital so patients can be closely monitored. They receive a single chemotherapy medication once a day for four days, followed by a few days of rest, to prepare the body for the modified stem cells to be reintroduced through infusion into a vein, similar to an IV drip.

Within about a month after the infusion of the modified cells, Hanna noted, the vast majority of patients will engraft with the new stem cells and will not need any more blood transfusions or other treatments as they will have cells established in their bone marrow capable of producing hemoglobin normally. Even in the few exceptional cases where gene therapy is not curative, patients need for blood transfusions will have been reduced substantially.

Aside from the new gene therapy treatment, other advances in recent years have greatly improved the quality of life for thalassemia patients, Hanna said.

A medication with the generic name luspatercept-aamt was approved by the FDA in 2019 to reduce patients reliance on blood transfusions. It is given in the form of an injection every three weeks and works by enhancing erythroid (red blood cell) maturation and reducing the need for blood transfusions by up to 50% in some patients.

Luspatercept-aamt can also be used to enhance outcomes in curative bone marrow transplantations, which have become more widely accessible in recent years thanks to a new transplant approach. Hanna was among the pioneers of the haplo-identical bone marrow transplant, which allows for non-identical-HLA (human leukocyte antigen) donors.

Hanna said the reduction in blood transfusions enabled by luspatercept-aamt means the patient has better health prior to bone marrow transplants, and fewer antibodies that could potentially attack transplanted bone marrow.

With the wider adoption of gene therapy and the use of luspatercept-aamt to improve bone-marrow transplant outcomes, almost any patient can be cured, Hanna said.

Researchers solve mystery of how statins improve blood vessel health – Stanford Medical Center Report

ATAC-seq revealed that simvastatin-treated cells had closed chromatin structures that reduced the expression of genes that cause the endothelial-to-mesenchymal transition. Working backward, the researchers found that simvastatin prevents a protein known as YAP from entering the nucleus and opening chromatin.

The YAP protein is known to play important roles in development, such as regulating the size of our organs, but also has been implicated in the abnormal cell growth seen in cancer.

To see the drug in context, the researchers tested simvastatin on diabetic mice. Diabetes causes subtle changes to blood vessels that mimic the damage commonly seen in people who are prescribed statins older patients who do not have a cardiovascular condition, Liu said.

They found that after eight weeks on simvastatin, the diabetic mice had significantly improved vascular function, with arteries that more easily relaxed and contracted.

If we can understand the mechanism, we can fine-tune this drug to be more specific to rescuing vascular function, Liu said.

The findings also provide a more detailed picture of the vascular disease process, which could help doctors identify and treat early signs of vascular damage.

Ive been taking statins for the past 10 years to keep my cholesterol down. I also knew it has good vascular effects. I just didnt know how it does it, said Wu, the Simon H. Stertzer, MD, Professor who is also the director of the Stanford Cardiovascular Institute. This study explains how.

Researchers from the University of North Texas and the Ohio State University College of Medicine contributed to this study.

The study was supported by funding from the National Institutes of Health (grants R01 HL130020, R01 HL150693, R01 HL163680, R01 HL145676, P01 HL141084, R01 HL141371, R01 HL126527, R01 HL15864, R01 HL161002, R01 HL155282 and 18CDA34110293), an American Heart Association SFRN grant, an AHA Career Development Award and the Tobacco-Related Disease Research Program.

About exagamglogene autotemcel (exa-cel)Exa-cel, formerly known as CTX001, is an investigational, autologous,ex vivoCRISPR/Cas9 gene-edited therapy that is being evaluated for patients with TDT or SCD characterized by recurrent vaso-occlusive crises (VOCs), in which a patients own hematopoietic stem cells are edited to produce high levels of fetal hemoglobin (HbF; hemoglobin F) in red blood cells. HbF is the form of the oxygen-carrying hemoglobin that is naturally present during fetal development, which then switches to the adult form of hemoglobin after birth. The elevation of HbF by exa-cel has the potential to alleviate transfusion requirements for patients with TDT and reduce painful and debilitating sickle crises for patients with SCD. Earlier results from these ongoing trials were published inThe New England Journal of Medicinein January of 2021.

Based on progress in this program to date, exa-cel has been granted Regenerative Medicine Advanced Therapy (RMAT), Fast Track, Orphan Drug, and Rare Pediatric Disease designations from theFDA for both TDT and SCD. Exa-cel has also been granted Orphan Drug Designation from theEuropean Commission, as well as Priority Medicines (PRIME) designation from theEuropean Medicines Agency(EMA), for both TDT and SCD. In the U.K., exa-cel has been granted an Innovation Passport under the Innovative Licensing and Access Pathway (ILAP) from the MHRA.

About CLIMB-111 and CLIMB-121The ongoing Phase 1/2/3 open-label trials, CLIMB-111 and CLIMB-121, are designed to assess the safety and efficacy of a single dose of exa-cel in patients ages 12 to 35 years with TDT or with SCD, characterized by recurrent VOCs, respectively. The trials are now closed for enrollment. Patients will be followed for approximately two years after exa-cel infusion. Each patient will be asked to participate in CLIMB-131, a long-term follow-up trial.

About CLIMB-131This is a long-term, open-label trial to evaluate the safety and efficacy of exa-cel in patients who received exa-cel in CLIMB-111, CLIMB-121, CLIMB-141 or CLIMB-151. The trial is designed to follow participants for up to 15 years after exa-cel infusion.

About CLIMB-141 and CLIMB-151The ongoing Phase 3 open-label trials, CLIMB-141 and CLIMB-151, are designed to assess the safety and efficacy of a single dose of exa-cel in patients ages 2 to 11 years with TDT or with SCD, characterized by recurrent VOCs, respectively. The trials are now open for enrollment and currently enrolling patients ages 5 to 11 years of age and will plan to extend to patients 2 to less than 5 years of age at a later date. Each trial will enroll approximately 12 patients. Patients will be followed for approximately two years after infusion. Each patient will be asked to participate in CLIMB-131, a long-term follow-up- trial.

About the CRISPR-Vertex CollaborationCRISPR Therapeuticsand Vertex Pharmaceuticals entered into a strategic research collaboration in 2015 focused on the use of CRISPR/Cas9 to discover and develop potential new treatments aimed at the underlying genetic causes of human disease. Exa-cel represents the first potential treatment to emerge from the joint research program. Under an amended collaboration agreement, Vertex now leads global development, manufacturing and commercialization of exa-cel and splits program costs and profits worldwide 60/40 withCRISPR Therapeutics.

Board of Regents medals awarded for teaching excellence … – University of Hawaii

The Regents Medal for Excellence in Teaching is awarded by the Board of Regents as tribute to faculty members who exhibit an extraordinary level of subject mastery and scholarship, teaching effectiveness and creativity and personal values that benefit students.

Rosanna Alegado is an associate professor of oceanography in the University of Hawaii at Mnoa School of Ocean and Earth Science and Technology (SOEST). Her work involves meaningful academic collaborations and partnerships with Indigenous communities.

She led SOESTs significant curriculum revision toward a required immersive course to ground all incoming graduate students in an understanding of working as marine biologists within Hawaiian culture. Its success has been recognized by the National Science Foundation with multi-year funding to foreground Indigenous knowledge, practices and values, and to transform and Indigenize higher education in STEM.

Alegado is regarded as an influential educator for other teaching faculty, as well as her students. She said, By challenging my students to integrate multiple didactic frameworks, one can achieve the most comprehensive understanding of a subject.

Her colleagues say that Rosie is not popular by being easy, and that her efforts are the epitome of teaching exceptionalism.

Tammy Hailipua Baker is an associate professor of theatre and dance in the University of Hawaii at Mnoa College of Arts, Languages & Letters. As a steward of Indigenous knowledge, she fulfilled that kuleana (responsibility) by building the Hawaiian Theatre Program, the only one of its kind focused primarily on performance.

A colleague, who was also her student in Hawaiian language, views the experience of acting in her productions as a master class in pedagogy. Professor Baker is continually supporting students and others in the production of 40 performers in speaking and singing lines individually and collectively. [She was] clearly the director throughout, nevertheless each actor (students) and production staff (teachers) were all made to feel their work was necessary and appreciated.

Baker is internationally recognized, the first from Hawaii to receive the Kennedy Centers Medallion of Excellence. A reviewer of her plays describes them as guides to restoring language and reclaiming the stories of generations of Indigenous populations; gifts to a culture whose language and history have been suppressed. Her transformative work shines through the passion, voice and aloha spirit of her students.

Richard C. Chen is an associate professor at the William S. Richardson School of Law at the University of Hawaii at Mnoa. He brings patience and empathy to all his interactions with students, never assuming the problem is with the students. This tenet is a teaching practice that extends into a way of modeling for the students as they enter the profession of law, as lawyers who seek to listen, learn and improve throughout their careers.

A cohort of 19 evening students for four straight semesters signed an enthusiastic letter of support for Chen, stating they collectively hope that our endorsement can begin to illuminate our appreciation of his talents as an educator and the positive impact he made during the formative stages of our legal education.

A colleague stated, Who wouldnt want to be in his classes? He is a professor whose empathy, kindness, brilliance and skill shine through in everything he does and it is elevating, inspirational and contagious.

Lincoln A. Gotshalk is a professor of kinesiology and exercise science in the University of Hawaii at Hilos College of Natural and Health Sciences. He is a musculoskeletal physiologist, anatomist and exercise physiologist with a strong background in muscular strength and power training and total body systemic response to exercise and stress.

He advises students, and teaches anatomy and physiology, research methods, nutrition and the science of diet and weight control, basic and advanced kinesiology courses, physiology of exercise and the science behind athletic training programs. Gotshalk is the director of the Laboratory for Exercise Sciences, which manages concurrent research projects.

Dr. Gotshalk most definitely has the ability to make every student feel appreciated and an important part of both the classroom and the lab group, noted a nominator. The experiences I have gained are ones I will never forget and I am thankful for all he has done to help me find my place in the UH Hilo community.

Karadeen Kam-Kalani is a professor of speech at Honolulu Community College. Her teaching philosophy recognizes that positive encouragement goes a long way in helping students gain the confidence they need to become better public speakers.

She is an inspiring and motivating instructor who strives to provide an environment for her students to foster self-discovery, steady improvement and growing confidence.

One student, self-conscious about his stutter, was nervous about taking a speech class. In Kam-Kalanis course, however, he learned to take a breath between sentences, use hand gestures to complement his talking points, and engage his audience with thoughtful questions. Her positive feedback helped him to improve his speaking capabilities.

The highlight of his learning journey came when one of his speeches was chosen as an example for other students to emulate. When he was asked how this recognition made him feel, his face lit up and he said, I felt awesome!

Tiffany-Joy Kawaguchi, serves as the program director and interim academic fieldwork coordinator in the occupational therapy assistant (OTA) program at Kapiolani Community College. Kawaguchi is an occupational therapist (OT) with more than 22 years of experience.

In 2015, Kawaguchi started a federally funded pro-bono clinic for the OTA program based on her belief that through doing, students become what they have the capacity to be. She utilizes meaningful experiences and intentional practice opportunities to help students access and then apply critical pieces of information to the OT process.

Dr. Tiff is undeniably dedicated to enabling her students to succeed, said an OTA program student. She accommodates numerous learning styles, grades fairly and offers detailed feedback so we know how to improve. Despite the endless list of things she has to do, she makes each one of us feel valued.

In 2016, Kawaguchi received the Laura N. Dowsett OT of the Year Award from the OT Association of Hawaii and was selected to represent Kapiolani CC in the inaugural Hawaii Association for Career and Technical Education Emerging CTE Leader Program in 2018. In 2021, Kawaguchi was awarded the Francis Davis Award for Excellence in Undergraduate Teaching.

Kamuela Kimokeo is the director of the Hawaii Music Institute and head of the music program at Windward Community College, where he teaches ukulele and slack key guitar. He created the groundbreaking Kaohekani Hawaiian music certificatea series of 8-week online classes taught by some of Hawaiis legendary artists.

Kimokeo shares his passion for music and instills in his students the joy of learning.

Ive come away from his courses a better musician and have a much better understanding and appreciation for the music of Hawaii, said one student. I am very proud to say that I have composed my own song.

The American Educational Research Association recently recognized Kimokeo for his research on song composition and performance as educational tools of personal empowerment. He earned his PhD in curriculum and instruction with a music emphasis, and his MEdT from UH Mnoa.

Kimokeo performs with Jerry Santos and his own N Hk Hanohano award-winning group Hiikua.

Monica LaBriola is an assistant professor of history in the University of Hawaii at Mnoa College of Arts, Languages & Letters. Her work focuses on engaging, yet challenging approaches to the area of Pacific studies, at the forefront of instructional excellence at UH Mnoa, while touching lives beyond the academic community.

At public forums and conferences, LaBriola draws diverse cultural workers passionate about the Pacific region as well as academics. Her guidance and vision on the development of resources in this area is praised by a colleague, who said that LaBriolas editorship of Teaching Oceania has impacted education across Hawaii, the Pacific, nationally and internationally.

She initiated and led two cohorts of Women in Pacific Studies, and is lauded by colleagues and students for successfully supporting the education of the student community experiencing the least educational equity at UH Mnoa and across the UH System.

A cohort member wrote, Professor LaBriola acknowledges the complexity of the university and encourages us to continue in academia while also dreaming of alternatives to knowledge production and dissemination.

Donald K. Maruyama is a culinary arts professor at Leeward Community College. Prior to joining Leeward CC as a chef instructor in 2007, he spent more than 20 years in the food and beverage industry.

He served as the culinary arts program coordinator from 2016 to 2020. For the past three years, Maruyama has been the professional arts and technology division chair, overseeing the automotive technology, culinary arts and digital media programs.

Dons strength as an instructor is his enthusiasm to share his personal experiences to his students about how true and real it is working in the industry as he does not sugarcoat, said Ron Umehira, dean of career and technical education. His strengths as a program and division colleague are his patience to listen, gather the facts, analyze and then support the best course of action.

Maruyama attended Kapiolani Community College, the University of Hawaii at Mnoa and Grinnell College. He currently serves as a Hawaii Culinary Education Foundation advisory board member, Hawaii Food & Wine Festival committee member, and on the board of directors for Hawaii Restaurant Association Education Foundation.

Summer Maunakea is an assistant professor in curriculum studies in the University of Hawaii at Mnoa College of Education. She grounds her teaching practices in academic rigor, agency and aloha. A colleague described observing her as expertly weaving place-based teaching and learning, ina (land)-based education and stewardship and Indigenous epistemology and practice.

She holds herself to high expectations as a teacher, knowing her instruction must have a positive intergenerational impact for students to grow holistically into healthy individuals capable of making pono (righteous) decisions and contributing to their communities.

For me, this is what love looks like in education, said a graduate student. The love and community that Professor Maunakea cultivates in the classroom supports immense intellectual experimentation and risk taking. I am immensely grateful for her teaching.

To a senior colleague, her teaching, research and service are considered to be visionary, meaningfully advocating for Indigenous education, sustainability, eco-justice, inclusive outdoor education and school-community partnerships.

Alexander Stokes is an assistant professor of cell and molecular biology at the John A. Burns School of Medicine at the University of Hawaii at Mnoa.

Advances in Cell Therapy – Technology Networks

Several cell therapies are now approved for treating human disease and many more are being developed. In this article, we review the latest research in cell therapy development, including advances made in the lab that show promise for translation to the clinic, to improvements in developing, testing and manufacturing.

Cell therapy is the transfer of cells into a patient, either cells from the patient themselves (autologous) or from a donor (allogeneic), for therapeutic purposes. Researchers have been attempting to use cells as treatments for hundreds of years, but for several decades, the only successful application was the use of bone marrow transplantation for leukemia.1 Today, key advances in understanding and genetic engineering of stem- and non-stem (somatic) cells have led to a series of cell therapy approvals. The first stem cell therapy was approved in 2014 for a rare condition called severe limbal stem cell deficiency (LSCD) caused by burns to the eye,2 and in 2017, the first chimeric antigen receptor (CAR) T-cell treatment, Kymriah (tisagenlecleucel), was approved for children and young adults with B-cell leukemia.3

Following these authorizations, the global market for cell-based therapies was valued at USD 21.6 billion in 2022 and is expected to expand to USD 62.4 billion in 2030.4 Although the largest market share is oncology, cell therapies are being explored for a wide range of other indications including central nervous system (CNS) and neurodegenerative diseases, autoimmune disease, cardiovascular disease and rare, orphan diseases.1

Cell therapies are either based on stem or somatic cells. In this article, we explore some examples highlighting both approaches, and the challenges of translating their promise in the clinic.

One of the fastest-moving areas of cell therapy is the development of CAR T cells in oncology. In this approach, T cells collected from patients or donors are engineered to express a chimeric antigen receptor that recognizes unique tumor antigens, grown in large numbers, and then administered back to patients. Despite the excitement in the field since the first approvals, there remain considerable challenges. These include the difficulty of reproducing the success seen in hematological cancers to solid tumors, and optimizing patient response in terms of the amount and duration of anti-tumor immunity. 1

For a long time, a major challenge for many of these therapies was manufacturing the cells, says David Zhang, a member of the Mooney lab at the Wyss Institute for Biologically Inspired Engineering, Harvard University. Then people figured out better ways of making lots of CAR T cells from a process perspective, with different bioreactor systems and other technological advancements. However, although it became possible to make large numbers of T cells from patient samples, there was still huge variation in individual patient responses to treatment. This led to retrospective analyses of attributes of the cells and factors during the manufacturing process that influence patient response. But the one thing that no one seemed to be looking at was how to optimize the way the T cells were getting activated in the first place, says Zhang. We knew that how we activated the cells was really important to the response we got, so we developed a system to fine tune activation parameters, and see how this affected their function.

The system is designed to mimic the function of the T-cell zone in human lymph nodes, by comprising biodegradable mesoporous silica rods that can be loaded with immune-stimulatory molecules called cytokines. The rods are coated with a lipid bilayer, to which you can attach different activating antibodies. T cells require three signals to be able to proliferate and differentiate: a T-cell receptor stimulation signal, costimulatory signals and a mitogenic growth signal, says Zhang. Our system allows T cells to naturally rearrange the artificial membranes to form an immunological synapse while supporting paracrine signaling, mimicking two important parts of physiological T-cell activation.

Zhang used this system to fine tune all the different parameters that could influence the ultimate T-cell product. But the one thing that really influenced the resulting cell phenotype and function was changing the amount or dose of T-cell stimulation the cells received.

We found that theres a quantitative relationship between your starting cell population, the amount of stimulation you provide, and the phenotype and function of the CAR T cells, says Zhang. We were able to fine-tune the levels of T-cell stimulation to match different phenotypes of the T cells obtained from patients with leukemia, which allowed us to produce CAR T cells with significantly enhanced tumor-clearing activity in a patient-specific manner.

The team used a simple machine learning model to find a pattern between these parameters, which Zhang says can easily be adapted to any starting cell population and any desired CAR T product characteristics, such as enhanced tumor memory, rapid proliferation or a durable response.5 This means that it becomes possible to fine-tune the product based on the patients original T-cell sample.

Given that T-cell samples are always phenotyped, and sometimes genotyped, at the start of manufacturing, similar strategies could be used to personalize the therapy using our approach, says Zhang. It means you can start with one donor sample, and potentially generate, for example, three different CAR T products that are better for different use cases or even different stages of the disease.

Active cell therapy drugs represent the latest in cancer treatment. Of these, chimeric antigen receptor (CAR) cell modalities are considered the most successful.Download this whitepaper to learn more about robust and reproducible methods for CAR expression detection, choosing the best reagents for your assay requirements, and next-generation CAR constructs and the future of cancer treatment.

An alternative to harvesting mature cells like T cells is to differentiate or engineer immature stem cells into your desired cell therapeutic product. One of the most active areas of research using this approach is in restoring or protecting the function of nerve cells. In Justin Ichidas lab at the University of Southern California, they are growing stem cells into different types of nerve cells to be used as treatments and for screening drugs. One of their projects, in collaboration with Jon-Paul Pepper, a specialist in facial reconstructive surgery, aimed to help people who sustained facial nerve injuries after an accident.6 These injuries often affect motor neurons in the face muscles, and although the nerve can regenerate it does so very slowly, by the time the muscle has already atrophied, explains Ichida. Because we can grow motor neurons from stem cells, we thought perhaps these cultivated cells could babysit the muscle, until the real nerve regenerates. To test this, they cut the sciatic nerve in mice and introduced motor neurons grown from induced pluripotent stem cells. The home-grown stem cells successfully extended their axons and innervated the muscle. After a couple of months, you could see there was a huge difference in preserved muscle mass, whereas the leg muscles in mice that did not receive the motor neuron therapy, completely atrophied away, says Ichida. What was really interesting, is that the nerve cells didnt require any additional stimulation to innervate the muscle in the way that a natural nerve would do.

Now, Ichida is turning his attention to another type of cell that can be derived from pluripotent stem cells, called microglia. There is growing evidence that microglia, which are the primary immune cells in the brain, play a critical role in the duration and progression of neurodegenerative diseases such as motor neuron disease (also known as amyotrophic lateral sclerosis; ALS).7 We studied stem cells derived from patients with C9orf72 ALS, the most common form, and found a neuroprotective population of microglia, says Ichida.

Although many of the microglial cells that we derived from patients are actually neurotoxic, we found that when they were grown in close proximity to a C9orf72 motor neuron, they switch into a protective state. These protective microglia do exist in the brains of ALS patients, but they are in the minority. Having made this discovery, Ichidas team transplanted the protective microglia into mice harboring a mutation that causes ALS and identified the signaling pathway that switches the microglia from a neurotoxic to a neuroprotective state. Now, they plan to engineer the cells to lock them into a neuroprotective state so they can be transplanted into patients. One hurdle is to see whether stem cells can be transplanted into the human brain, says Ichida. Its been recently shown in rodents that you can transplant microglia and that the grafts extend broadly throughout the brain, so we have some proof of concept already there.

Further proof of concept comes from another study where engineered stem cells were transplanted into the CNS and showed early clinical promise. In the first clinical trial of its kind, a team of investigators from Cedars-Sinai Medical Center demonstrated that it was possible to deliver a combined stem cell and gene therapy into the spinal cord of patients with ALS.8 The stem cells produce a protein called glial cell line-derived neurotrophic factor (GDNF) which can promote the survival of motor neurons. The trial has proved the short-term safety of the approach, and now larger numbers of patients are needed to test its efficacy.

The key in ALS, and its very similar in Parkinsons disease and Alzheimers disease, is that these are very genetically diverse diseases, and so for most patients we dont have a full understanding of the genetic causes behind each persons condition, says Ichida. What we can do is take these patients stem cells and remake their neurons in a dish. Then, because these neurons in the lab mimic the same disease process in the patient, we can reprogram them, or we can use them to test new drugs that will work. In this way, were going to find treatments that are more likely to work across the whole breadth of the ALS population.
