Cancer Centers Combine Expertise To Optimize Advanced Immunotherapy Strategies

Washington /PRNewswire/ - Physician researchers from Georgetown Lombardi Comprehensive Cancer Center, in Washington, D.C., and John Theurer Cancer Center (JTCC) in Hackensack, New Jersey, announce today the formation of the Regional Immunotherapy Discovery Program.

The Regional Immunotherapy Discovery Program will accelerate discovery and implementation of a new immunotherapy approach, which combines the full potential of two potent strategies currently used in treating cancer: cancer immunotherapy and bone marrow stem cell transplantation.

"We are at the dawn of an exciting new era," explains Louis M. Weiner, MD, director of Georgetown Lombardi. "The future of successful cancer therapy will rely heavily upon immunotherapythe power of the immune system to recognize and destroy malignant cells, and then to remember and eliminate cancers that try to recur."

Georgetown Lombardi, part of Georgetown University Medical Center and MedStar Georgetown University Hospital, and JTCC, part of Hackensack University Medical Center, already offer the most advanced clinical trials available using investigational immunotherapy drugs. And both offer transplant programs that manipulate the immune cells via both allogeneic (donor) and autologous (patient) transplants to treat patients with blood cancers.

"By combining these two strategies in attacking cancer, we believe it's possible to optimize the true promise of immunotherapy and extend treatment options to specific patient populations," says Andr Goy, MD, MS, chairman of JTCC. "This approach is only now emerging at a very limited number of cancer centers in the U.S."

One example of the new strategy would be to combine an immunotherapy drug such as a PD-1 inhibitor, which selectively unleashes immune cells, with an adoptive cellular therapy to assist reconstitution of the immune system following immune cell-depleting chemotherapy. This strategy is designed to deliver an overwhelming blow against a blood cancer.

In addition to the therapeutic impact, the Regional Immunotherapy Discovery Program has broad regional accessibility via physician researchers from Georgetown Lombardi in Washington, the MedStar Georgetown Cancer Network in Maryland and Washington, Regional Cancer Care Associates (RCCA) with offices throughout New Jersey, and JTTC in Hackensack. This means cancer patients living in the northeast corridor between Washington and the New York metropolitan area will have easy access to state-of-the-art immunotherapy clinical trials and care.

Michael B. Atkins, MD, an internationally recognized expert in immunotherapy and deputy director of Georgetown Lombardi, and Andrew L. Pecora, MD, president of RCCA, will lead the program, which builds on an oncology affiliation that Georgetown Lombardi, a National Cancer Institute (NCI) designated-comprehensive cancer center, and JTCC established in 2013. As part of the affiliation, the two institutions are working toward becoming an NCI-recognized consortium center, in which investigators from separate but collaborating scientific institutions contribute actively to the development and actualization of a specific cancer research agenda.

Future heat stroke treatment found in dental pulp stem cells

PUBLIC RELEASE DATE:

5-Jun-2014

Putnam Valley, NY. (June 5, 2014) Scientists in Taiwan have found that intravenous injections of stem cells derived from human exfoliated deciduous tooth pulp (SHED) have a protective effect against brain damage from heat stroke in mice. Their finding was safe and effective and so may be a candidate for successfully treating human patients by preventing the neurological damage caused by heat stroke.

The study is published in a future issue of Cell Transplantation and is currently freely available on-line as an unedited early e-pub at: http://www.ingentaconnect.com/content/cog/ct/pre-prints/content-CT1100Tseng.

"Heat stroke deaths are increasing worldwide and heat stroke-induced brain injury is the third largest cause of mortality after cardiovascular disease and traumatic brain injury," said study lead author Dr. Ying-Chu Lin of the Kaohsiung Medical University School of Dentistry, Kaohsiung City, Taiwan. "Heat stroke is characterized by hyperthermia, systemic inflammatory response, multiple organ failure and brain dysfunction."

To investigate the beneficial and potentially therapeutic effects afforded by the protective activities of self-renewing stem cells derived from human exfoliated deciduous teeth, the scientists transplanted SHED into mice that had suffered experimental heat stroke.

According to the research team, these cells have "significantly higher proliferation rates" than stem cells from bone marrow and have the added advantages of being easy to harvest and express several growth factors, including vascular endothelial growth factor (VEGF), and they can promote the migration and differentiation of neuronal progenitor cells (NPCs).

"We observed that the intravenous administration of SHED immediately post-heat stroke exhibited several therapeutic benefits," said Dr. Lin. "These included the inhibition of neurological deficits and a reduction in oxidative damage to the brain. We suspect that the protective effect of SHED may be related to a decreased inflammatory response, decreased oxidative stress and an increase in hypothalamo-pituitary-adrenocortical axis activity following the heat stroke injury."

There are currently some drawbacks to the experimental therapy, said the researchers. First, there is a limited supply of SHED. Also, SHED transplantation has been associated with cancer and immune rejection.

How planarians maintain their stem cell pools over generations

6 hours ago Fig. 1: Pluripotent stem cells enable planarians to achieve extraordinary feats of regeneration. (A) Planarians are able to re-grow an entire head in a matter of a few days. (B) The stem cells and their early offspring can be found almost all over the worms body. During regeneration, when a lot of new tissue has to be produced, they are able to generate a wide variety of cell types. The cell nuclei are marked in blue.

Planarians are known as masters of regeneration: they can re-build any part of their bodies after amputation. This ability relies on a large number of pluripotent stem cells. To further investigate the mechanisms that enable planarians to maintain their stem cell pool over generations, scientists have now established a method for analysing the composition of planarian stem cells and the turnover of their proteins. They discovered a protein that is not only required for the maintenance of the stem cell pool in planarians, but might also be active in the pluripotent stem cells of mammals.

Of earthworms and flatworms

Everyone knows the myth about earthworms: if you cut them in half, you get two worms. Nothing could be further from the truth, alas. However, if the earthworm is replaced by a flatworm, the two parts can survive these childish experiments. What's more, be it skin, intestine or brain, the body part lost through cutting will simply grow again in a matter of days. The creatures involved here are planarians[1], a class of flatworms that are so flat that they need neither lungs nor a heart to take in and distribute oxygen in their bodies. So simple and yet so ingenious? It would appear so. Regeneration studies involving these animals have shown that a dismembered planarian can generate several hundred tiny animals, hence they could "almost be called immortal under the edge of a knife" (Dalyell, 1814). The astonishing aspect here is that both the blueprint and construction material for the regeneration process must be contained in each of the fragments: a small piece of tail, for example, becomes a complete worm under the animal's own strength and using existing resources.

Not the preserve of youth: pluripotency also available in adults

So where do the components needed to rebuild the cellular structures come from? In their search for the answer to this question, scientists have a population of small cells in their sights, namely the approximately five-micrometre-long neoblasts. These cells are found almost everywhere in the planarian body and behave like stem cells: they divide, renew and can form the different cell types that have been lost as a result of amputation (Fig. 1). When the planarian loses a body part or discards its tail for reproduction, the neoblasts are reactivated and migrate to the wound. They divide there and their offspring form a blastema, in which as a result of interplay between various extra- and intra-cellular factors important differentiation and patterning processes take place. Thanks to these processes, in turn, complex structures like the brain are formed. If the neoblasts are eliminated through radiation, for example, the planarian loses its ability to regenerate and dies within a few weeks. The fact that, following transplantation into an irradiated, neoblast-free worm, a single neoblast can produce all cell types and enable the host worm to regain its ability to regenerate shows that at least some neoblasts are pluripotent [2]. In healthy mammals, pluripotency, that is the ability of one cell to produce any given cell type found in an organism, e.g. muscle, nerve or pancreas cells, only arises in the early embryonic stage. Therefore, stable pluripotency in the adult organism is something special but not impossible as long as mechanisms exist for conserving this characteristic as is clearly the case with the planarians.

An in-vivo Petri dish for pluripotent stem cells

The preservation of pluripotency has been an important topic in stem cell research for years, and has mostly been examined up to now using isolated embryonic stem cells. Important transcription factors that can induce and preserve pluripotency were discovered in the course of this research. So what can planarians contribute to the current research if their stem cells cannot be cultivated and reproduced outside of the body? This is precisely where the strength of the planarians as a model system in stem cell research lies: the combination they can offer of a natural extracellular environment and pluripotent stem cells. Whereas cultivated stem cells are normally taken out of their natural environment and all important interactions with neighbouring cells and freely moving molecules are interrupted as a result, the stem cells in planarians can be observed and manipulated under normal conditions in vivo. Therefore, planarians are of interest as "in-vivo Petri dishes" for stem cells, in which not only their mechanisms for preserving pluripotency can be studied, but also their regulation and contribution to regeneration.

A venerable old worm meets ultra-modern next-generation technologies

Although planarians have been renowned as masters of regeneration and research objects for generations, they have undergone a genuine explosion in research interest in recent years. In particular, the possibility of switching off specific genes through RNA interference (RNAi) and the availability of the genome sequence of Schmidtea mediterranea, a planarian species which is especially good at regenerating itself, have contributed to this surge in interest. With the development of modern sequencing procedures, that is 'next generation sequencing', gene expression profiles that provide information about the specific genes activated in particular cells or tissues at particular points in time can now be produced on a large scale. Hence, it is possible to examine which messenger RNAs (mRNAs) are produced that act as molecular templates for the production of proteins. For example, hundreds of these mRNAs are produced after the amputation of a worm's head and their proteins provide potential regulators of the regeneration process [3; 4]. However, the real work only starts here: the extent to which the presence of a particular mRNA also reflects the volume of protein that is active in the cell remains to be determined. It is mainly the proteins in the form of enzymes, signalling molecules and structural elements, and not their mRNAs, that ultimately control the majority of cellular processes. In addition, their production using mRNA templates and their lifetime are precisely regulated processes and the frequency with which an mRNA arises cannot provide any information about these processes. The time has come, therefore, to develop experimental approaches for planarians that extend beyond gene expression analysis and lend greater significance to the subsequent regulatory processes.

Benefit planned to help firefighter

SHOREWOOD Derek Hogg has spent his life helping others. Hes not completely comfortable having that situation reversed.

Its very humbling to see all this support, but its hard for me to ask for help when I dont think a thank you will cut it. I owe something to everybody, so the best I can do is give 110 percent to my [recovery], he said.

Hogg, 31, is a Joliet West High School graduate who has worked full-time on the Kankakee Fire Department and part-time on the Wilmington Fire Department for the past six years.

When Hogg first noticed a muscle twitch last year, he didnt believe it was a big deal, but saw a Joliet neurologist at his fathers urging. Further tests in Chicago and at the Mayo Clinic in Minnesota indicated Hogg has amyotrophic lateral sclerosis, also known as Lou Gehrigs disease.

Every doctor I saw said people live an average of 3 to 5 years, but I have young sons. I cant accept that. I have to do something, Hogg said. He and his wife, Holly, are the parents of Paxton, 2, and 4-month-old Hayden.

Hoggs research found a doctor in California who is optimistic that stem cell therapy could slow the progression of Hoggs disease, he said. Stem cell treatment, which is not covered by insurance, costs $25,000.

James and Tina Kilgore are holding a benefit Saturday at the Moose Lodge to cover the cost of their brother-in-laws treatment.

Dereks just such a good guy whos spent his whole life helping others. I think a lot of people want to help him fight this battle, Tina Kilgore said.

The $25 tickets include hamburgers and hot dogs, and an entry for the big-screen television set being offered as a door prize. Musicians You Beside Me will perform at 2 p.m. and Alex Hoffer will play at 3 p.m. The Joliet Police Pipes and Drums will play at 5 p.m. and a DJ will play music until 8 p.m.

A petting zoo and face-painting will be on hand for kids, along with police and fire vehicles at 3 p.m. and a ventriloquist at 4 p.m.

Stem Cell Therapy || Rheumatoid Arthritis Treatment …

Rheumatoid Arthritis

Currently, RA is treated with immune suppressive agents such as steroids, methothrexate, cyclosporine, gold, and more recently infliximab (Remicade). Despite inducing temporary improvement, these approaches possess long-term adverse effects due to non-specific inhibition of immune responses. Additionally, current treatments do not address the issue of damage that has already occurred to the joints or extra-articular tissues.

Advancements in rheumatoid arthritis (RA) treatment protocols and introduction of targeted biological therapies have markedly improved patient outcomes, despite this, up to 50% of patients still fail to achieve a significant clinical response.

Stem cell therapy has been demonstrated to induce profound healing activity in animals with various forms of arthritis. For example, the company Vet-Stem routinely utilizes stem cells in horses with various joint deformities to accelerate healing. Besides healing of damaged tissues, stem cells have the unique ability to modulate the immune system so as to shut off pathological responses while preserving ability to fight off disease. Stem cells and specifically, mesenchymal stem cells home to inflamed tissue and start producing anti-inflammatory agents. These mediators act locally and do not suppress the immune response of the patients whole body. Additionally, mesenchymal stem cells induce the production of T regulatory cells, a type of immune cell whose function is to protect the body against immunological self-attack.

The Stem Cell Institute uses adult stem cells called allogeneic mesenchymal stem cells to treat rheumatoid arthritis. These cells are harvested from human umbilical cords donated after normal, healthy births. All mothers who donate umbilical cords undergo infectious disease testing and medical history screening. Proper written consent is obtained from each family prior to umbilical cord donation.

All mesenchymal stem cells harvested from umbilical cords are screened for infectious diseases to International Blood Bank Standards before they are cleared for use in treatments.

Only about one in ten umbilical cords pass our rigorous screening process.

The bodys immune system is unable to recognize human umbilical cord tissue (HUCT)-derived mesenchmyal stem cells as foreign and therefore they are not rejected. HUCT stem cells have been administered thousands of times at the Stem Cell Institute and there has never been a single instance rejection (graft vs. host disease). Umbilical cord-derived mesenchymal stem cells also proliferate/differentiate more efficiently than older cells, such as those found in the fat and therefore, they are considered to be more potent.

New stem cells may help in battling multiple sclerosis

The great promise of stem cells may finally be getting close for multiple sclerosis patients.

Stem cells, which have the power to transform into other types of cells, have been much anticipated for more than a decade as a way to treat or even cure diseases like MS, Parkinson's, blindness, and spinal cord injuries. But it's taken time to turn that promise into a workable reality.

Two new studies, both published in the journal Stem Cell Reports, suggest that researchers are getting close.

"We haven't landed on the moon yet, but we've tested in the rockets," said Jeanne Loring, author of one of the studies and a professor and director of the Center for Regenerative Medicine at The Scripps Research Institute in La Jolla, Calif.

Her study found that a certain type of stem cell, injected once into the spinal cords of mice with an MS-like condition, could dramatically improve the animals for at least six months.

The mice's immune systems almost immediately rejected and destroyed the cells, known as human embryonic stem cell-derived neural precursor cells. But the cells seemed to trigger a long-lasting benefit, dampening inflammation to slow the disease's progression, and repairing the damaged sheathing around nerve cells that is the hallmark of MS, according to Thomas Lane, a neural immunologist at the University of Utah who helped lead the research.

The other study, led by Robert Lanza, chief scientific officer of Advanced Cell Technology, a Massachusetts-based biotech, showed that mice with an MS-like disease could be restored to near normal by injecting them with a different type of stem cell. When injected, these cells ?? mesenchymal stem cells derived from human embryonic stem cells ?? were able to home in on damaged cells in the nervous system, even crossing the blood-brain barrier, Lanza said.

They not only reduced the symptoms of the disease, but prevented more damage to nerve cells, he said.

The two studies together "speak to the changing role of stem cells and their potential as treatment strategies for MS," said Tim Coetzee with the National Multiple Sclerosis Society, an advocacy group. The idea of using stem cells in MS has been around for a while, but these two studies overcome some of the challenges of finding a therapy that can be consistent and effective for many people.

"They set the stage quite impressively for potential work in humans," he said, with clinical trials likely within the next few years.

Stem cells found to play restorative role when affecting brain signaling process

PUBLIC RELEASE DATE:

5-Jun-2014

Contact: Robert Miranda cogcomm@aol.com Cell Transplantation Center of Excellence for Aging and Brain Repair

Putnam Valley, NY. (June 5, 2014) A study by a Korean team of neuroscientists has concluded that when mesenchymal stem cells (MSCs; multipotent structural stem cells capable of differentiation into a variety of cell types) are transplanted into the brains of mice modeled with Alzheimer's disease (AD), the cells stimulate neural cell growth and repair in the hippocampus, a key brain area damaged by AD. The finding could lead to improved AD therapies.

The study will be published in a future issue of Cell Transplantation and is currently freely available on-line as an unedited early e-pub at: http://www.ingentaconnect.com/content/cog/ct/pre-prints/content-CT1059Oh.

Neuroscientists know that Alzheimer's disease is caused by the presence of amyloid-B (AB) "plaques" and "tangles" in the brain's network of neurons. Recently, a protein signaling pathway called "Wnt" (Wingless-type mouse mammary tumor virus (MMTV) related integration site family) which plays a role in embryonic development as well as the development of some diseases, such as cancer, has been linked to Alzheimer's disease. Researchers speculate that an interruption in the Wnt pathway signaling process caused by the AB plaque buildup may have an impact on potential brain cell renewal processes, called neurogenesis. Evidence has indicated that the Wnt signaling pathway plays an important role in the pathogenesis of AD.

This study was carried out to determine if MSCs benefitted neurogenesis in the hippocampus by "modulating" the Wnt pathway in such a way that that the MSCs are able to differentiate into neuronal progenitor cells (NPCs) that could help rebuild the affected areas of the brain.

"Recent studies have shown that MSCs express various proteins related to the Wnt pathway," said study co-author Dr. Phil Hyu Lee, Department of Neurology, Yonsei University College of Medicine in Seoul, South Korea. "It has also been determined that MSCs derived from bone marrow produce biologically active Wnt proteins that may counteract the negative influence of AB on neuronic activity."

The authors report that MSC treatment of AD in cellular and animal models significantly increased hippocampal neurogenesis and enhanced neuronal differentiation of NPCs.

"Our data suggest that the modulation of adult neurogenesis and neuronal differentiation to repair the damaged AD brain using MSCs could have a significant impact on future strategies for AD treatment," the researchers concluded.

Animal Medical Center of New York Seeks Candidates for Clinical Trial for Cats with Chronic Kidney Disease to Receive …

New York, NY (PRWEB) June 04, 2014

The Animal Medical Center of New York is offering stem cell therapy provided through Vet-Stem and long-term management in a clinical trial for qualifying cats with chronic kidney disease (CKD). The ultimate goal of this study is to investigate the use of stem cells (obtained from the patients own fat) in aiding the enhancement of renal (kidney) function by their regenerative capabilities, with the goal of improving survival in cats with CKD.

Currently there are no therapeutic options for cats with CKD other than renal transplantation, which is not typically an option for most owners. Most efforts aim at improving uremic signs with food, dietary supplements, and antacids, but there are no current methods for improving function of the kidney directly. CKD is the leading cause of death in older cats, and 35% of cats will develop CKD at some point.

Since renal failure is so common in cats and renal cell death is the ultimate result, improving the health and environment of the cells that remain could improve the overall function of the kidneys and ultimately improve the survival times and quality of life in patients. The aim is to use the cats own adipose (fat) derived stem cells to improve renal function directly, as stem cells are thought to improve, repair, and aid in the growth of damaged tissue.

The potential health benefits of using stem cells to combat CKD include renal regeneration, anti-fibrotic effects, a decrease in proteinuria (also called urine albumin or an abnormal amount of protein in the urine), and an improvement in the Glomerular Filtration Rate (GFR used to help measure kidney function). AMC is offering free fat collection, isolation of the stem cells from the fat, and intra-arterial injection for qualifying cats, as well as free follow-up for three years. Qualifying cats must be diagnosed with IRIS Stage 3 CKD that have had no other experimental therapies. Potential candidates must undergo a full workup and have no history of urinary tract stone disease or the presence of other concurrent, unrelated disease.

Allyson Berent, DVM, DACVIM and Catherine E. Langston, DVM, DACVIM will be leading the three year study, and invite owners with a cat that has been diagnosed with CKD to call 212.329.8763 for more information on qualifying for the clinic trial. To learn more about the study go to http://www.amcny.org/clinicaltrials. To watch a short special interest film about one cats success go to http://www.vet-stem.com/pr_detail.php?id=49.

The Animal Medical Center in New York City is a federally recognized 501(c)(3) non-profit veterinary center that has been a national leader in animal care since 1910. As an academic veterinary hospital, The AMC promotes the health and well-being of companion animals through advanced treatment, research and education. Stem Cell Therapy through Vet-Stem has been offered at AMC since 2008 to treat pain associated with chronic osteoarthritis. To find out more about AMC and their stem cell therapy services for osteoarthritis go to http://www.amcny.org/surgery/neurosurgery/stem-cell-therapy.

Vet-Stem, Inc. was formed in 2002 to bring regenerative medicine to the veterinary profession. The privately held company is working to develop therapies in veterinary medicine that apply regenerative technologies while utilizing the natural healing properties inherent in all animals. As the first company in the United States to provide an adipose-derived stem cell service to veterinarians for their patients, Vet-Stem, Inc. pioneered the use of regenerative stem cells in veterinary medicine. The company holds exclusive licenses to over 50 patents including world-wide veterinary rights for use of adipose derived stem cells. In the last decade over 10,000 animals have been treated using Vet-Stem, Inc.s services, and Vet-Stem is actively investigating stem cell therapy for immune-mediated and inflammatory disease, as well as organ disease and failure.
