Editing Muscle Stem Cells with CRISPR Treats Mouse Model of Muscular Dystrophy – DocWire News

A research team from the University of Missouri School of Medicine has recently used CRISPR to edit a genetic mutation that contributes to Duchenne muscular dystrophy (DMD). This rare and debilitating genetic disorder is characterized by loss of muscle mass and physical impairment. By using this powerful gene-editing technology, these MU School of Medicine researchers have successfully treated mouse models of the disease. This work was published this summer in the journal Molecular Therapy.

Those with DMD possess a specific mutation that hinders the production of the dystrophin protein, which contributes to the structural integrity of muscle tissue. In the absence of this protein, the muscle cells weaken and eventually die. Pediatric patients with the condition often lose their ability to walk and can even lose the function of muscles that are essential for respiration and heart contractions.

Research has shown that CRISPR can be used to edit out the mutation that causes the early death of muscle cells in an animal model, explained senior author Dongsheng Duan, PhD, Margaret Proctor Mulligan Professor in Medical Research in the Department of Molecular Microbiology and Immunology at the MU School of Medicine. However, there is a major concern of relapse because these gene-edited muscle cells wear out over time. If we can correct the mutation in muscle stem cells, then cells regenerated from the edited stem cells will no longer carry the mutation. A one-time treatment of the muscle stem cells with CRISPR could result in continuous dystrophin expression in regenerated muscle cells.

Working alongside other researchers from MU, the National Center for Advancing Translational Sciences, Johns Hopkins School of Medicine and Duke University, Duan aimed to genetically modify muscle stem cells in mice. These scientists first edited the gene using an adeno-associated virus known as AAV9. Being this specific viral strain was recently approved by the FDA in treating spinal muscular atrophy, the researchers saw it as a viable candidate in treating DMD.

We transplanted AAV9 treated muscle into an immune-deficient mouse, said lead author Michael Nance, an MD-PhD program student in Duans lab. The transplanted muscle died first then regenerated from its stem cells. If the stem cells were successfully edited, the regenerated muscle cells should also carry the edited gene.

Upon analyzing the regenerated muscle tissue, the researchers found that its cells contained the edited gene, supporting their reasoning. The team then tested whether the muscle stem cells in mice with DMD could be genetically edited using CRISPR. These findings also supported their hypothesis, with the stem cells in the diseased tissue sustaining these edits and the regenerated cells successfully producing dystrophin.

This finding suggests that CRISPR gene editing may provide a method for lifelong correction of the genetic mutation in DMD and potentially other muscle diseases, explained Duan. Our research shows that CRISPR can be used to effectively edit the stem cells responsible for muscle regeneration. The ability to treat the stem cells that are responsible for maintaining muscle growth may pave the way for a one-time treatment that can provide a source of gene-edited cells throughout a patients life.

Duan and colleagues hope that future research will help this stem cell CRISPR therapy become a revolutionary treatment for children with DMD.

Testing chemicals for birth defects using stem cells, not mice – UC Riverside

Researchers at the University of California, Riverside, are part of an ambitious plan at the U.S. Environmental Protection Agency, or EPA, to eliminate animal testing by 2035. Their contribution: developing a way to test whether chemicals cause musculoskeletal birth defects using lab-grown human tissue, not live animals.

Nicole zur Nieden, an associate professor of molecular, cell, and systems biology, and David Volz, an associate professor of environmental toxicology, are both experts on alternatives to regulatory toxicity testing and chemicals policy and regulation. They received $849,811 to grow human stem cells into bone-like tissue to test industrial and environmental chemicals that might interfere with fetal growth.

Birth defects that affect musculoskeletal tissues can be caused by chemical ingredients in pesticides, fungicides, paints, and food additives. Harmful chemicals must be identified through testing in order to be regulated. Currently, this testing is done on live animals, usually rodents such as mice.

The UC Riverside project, led by zur Nieden, will stimulate human pluripotent stem cells, which have the capacity to develop into any sort of cell, with agents that direct them to form bone cells. The cells will pass through the same developmental stages and be subject to the same molecular cues as in a human embryo. The researchers will expose the cells to selected chemicals at critical junctures, then assess them using advanced imaging and next-generation sequencing techniques.

Bone cells can develop through three different pathways. zur Nieden will use chemicals known to affect specific routes of bone development to look for patterns in how the chemicals affect these origins. The patterns will serve as blueprints for testing unknown chemicals. Next, the researchers will test unknown chemicals and compare them to previously compiled libraries of compounds that have already been tested in animals to see how accurate the petri dish, or in vitro, tests are for assessing risk.

A hallmark feature of bone-forming cells is that they make a bony matrix out of little crystals called hydroxyapatite, which eventually form calcium phosphate, the white stuff on the surface of all bones. Cost-saving visual analysis can help identify defects in calcium.

Calcium crystals appear white when viewed with your eyes, said zur Nieden. But when you view the cultures using phase contrast microscopy, it inverts the light so the normal crystals appear black. Abnormal crystals will have more white and shades of gray. You can use an image analysis algorithm to measure the blackness in images to determine if the calcium has formed correctly or not.

Scientists have known for a long time that animals differ from humans in important developmental and physiological ways, and that animal test results are not always reliable for people. Moreover, animal research is expensive and time-consuming, as well as increasingly untenable for ethical reasons. Non-animal alternatives have been in development for nearly 25 years, and some are already standard.

To the general public, the EPAs announcement seemed to come out of nowhere, said Volz, whose lab will sequence messenger RNA in chemical-exposed bone cells from zur Niedens lab to look for changes in gene expression. It didnt happen overnight. That train has already left the station.

Volz said the EPAs Science to Achieve Results Program, through which UC Riverside received the new grant, has been funding research on animal alternatives for more than 10 years.

The EPAs plan to end animal testing by 2035 follows up on earlier changes to the Toxic Substances Control Act, or TSCA, enacted in 1976. TSCA authorizes the EPA to regulate chemicals found in consumer products such as cleaning agents, furniture, paint, carpeting, clothing, and other consumer goods. Regulation under TSCA does not apply to chemicals in food, drugs, cosmetics, and pesticides, which are regulated under different laws.

Even after TSCA, thousands of common chemicals used in everything from plastic to sunscreen have never been tested for safety in humans. In 2016, Congress passed the Lautenberg Chemical Safety Act, amending TSCA to close the loophole for industrial chemicals. The law mandated the EPA to evaluate existing chemicals with clear and enforceable deadlines, and to develop risk-based chemical assessments. It promoted the use of non-animal testing methods, a move sought by both industry and animal rights groups.

The new EPA plan introduces an aggressive timeline for ramping up development of non-animal tests that can accurately predict toxicity in humans. Volz said the United States lags behind some other countries around the world, which have already greatly reduced animal testing. He said he interacts with fewer and fewer students interested in research involving animal experiments, and that our culture is shifting toward a desire to reduce animal suffering.

But neither Volz nor zur Nieden are sure animal testing can ever be replaced completely, a position echoed by the EPA memo, which states that after 2035, animal tests will be approved on a case-by-case basis. Some chemicals, for example, are not directly toxic to cells but become toxic after they are metabolized in the body.

If your result is that the chemical does not interfere with a human stem cell developing in a dish, how sure can you be thats not really happening in humans? The best way we have to assess that is an animal experiment, zur Nieden said. At the same time, we want to do this in an appropriate way. We need to think about, is this really necessary? Can we look at the question some other way?

zur Nieden thinks we need a tiered system, with in vitro tests weeding out the most toxic chemicals first, and animal tests used where in vitro tests dont reveal toxicity.

If you cannot fully replace an animal test with an in vitro method, you can at least decrease suffering of the animal. If you think about a highly toxic chemical that has effects on the mom as she is exposed during pregnancy as well as on the developing embryos, if you can use an in vitro test system to find all these strong toxic chemicals, you will not need to test them in an animal, she said.

Previous versions of the test system zur Nieden will use for the new musculoskeletal research have been able to identify embryotoxic chemicals for other tissues, such as heart tissue, with almost 100% accuracy.

Mutant Tau Stiffens Axon Cytoskeleton Near Soma – Alzforum

20 Sep 2019

Changes to the microtubule-binding protein tau cause it to fall off these struts and aggregate, forming neurofibrillary tangles. But is that the reason for tau toxicity? A study in the September 18 Neuron suggests that V337M tau, a variant associated with frontotemporal dementia, causes morphological changes at the base of the axon. Scientists led by Li Gan, then at the Gladstone Institute of Neurological Disease, San Francisco, found that neurons derived from patients with the mutation are hyperexcitable. They had unusually short, unresponsive axon initial segments (AIS), which usually initiate action potentials and steer neuronal plasticity. Gans results suggest that this FTD mutation robs neurons of a mechanism for maintaining electrical homeostasis.

The initiation of axon potential firing has received little attention in neurodegeneration research, said Jrgen Gtz, What I really like about this paper is the use of complementary techniques to mechanistically dissect the effect of FTD mutant tau on neuronal function.

Because many FTD-causing tau mutations occur in the microtubule-binding domain, scientists believed they lead to disease by weakening microtubules (Rossi and Tagliavini, 2015; Hong et al., 1998). However, studies have mostly found that removing tau leaves microtubules intact (Roberson et al., 2007). On the other hand, FTD patients have hyperexcitable neurons, seizures, and highly synchronized neuronal networks (Beagle et al., 2017). Could the mutant protein alter neuronal excitability in some way?

Plasticity Deficit. In iPSC-derived wild-type neurons (left) the axon initial segment (green) is long initially (top)and shrinks after chronic depolarization with KCl (bottom). In neurons with V337M tau (right), the AIS starts out and remains short. [Courtesy of Sohn et al., 2019.]

To find out, first author Peter Dongmin Sohn and colleagues focused on the AIS. The closest part of the axon to the soma, the AIS contains a high concentration of voltage-gated ion channels and triggers action potentials. It regulates neuronal excitability by lengthening or shrinking in response to less or more activity, respectively. This remodeling relies on a reorganization of the cytoskeleton, in particular ankyrin G. Staining for AnkG revealed that the AIS shrank, making it less excitable, when Sohn and colleagues depolarized wild-type neurons for two days (see image at left). In contrast, in iPSC-derived neurons from a patient with the V337M tau mutation, the AIS was about 20 percent shorter to begin with, and chronic depolarization did not change its length. This suggested the region was less plastic. If the researchers used CRISPR-Cas9 to correct the mutation, then the initial length of the AIS and its plasticity matched that of wild-type cells.

The researchers next compared electrophysiological properties of mutant and control neurons. In culture, neurons carrying mutant tau more often fired in synch, having longer network bursts containing more spikes, than did wild-type neurons. This suggested the mutated tau caused a type of hyper-synchrony. After a two-day depolarization, these neurons fired six times faster, while the rate stayed steady in isogenic controls.

To find out how the mutant tau might be interfering with homeostatic control of neuronal excitability, the authors examined tau binding partners in the AIS. Tau interacts with end-binding protein 3 (EB3), another component of the AIS cytoskeleton (Sayas et al., 2015). EB3 stabilizes the AIS by linking microtubules to AnkG.

Getting a Grip. At left, wild-type tau (blue) binds EB3 (green), which anchors AnkG (yellow) to microtubules (white). To the right, mutant tau (red) binds more tightly to EB3 and clamps it in place, making the AIS rigid and unchanging. [Courtesy of Sohn et al., 2019.]

Sohn and colleagues determined that tau binds EB3 directly, and that V337M tau does so more tightly. In tau V337M neurons, EB3 levels in the AIS were 40 percent higher than in wild-type. Whats more, rather than distributing throughout the AIS cytosol, EB3 gathered just under the plasma membrane, corralling AnkG. In all, the data suggested that through its grip on EB3, tau concentrated the protein in the AIS and immobilized AnkG such that it couldnt respond to electrical activity.

Would removing EB3 rescue plasticity in V337M neurons? Suppressing translation with siRNA, Sohn reduced levels by 80 percent, which restored both the length and plasticity of the AIS. Reducing mutant tau in these neurons by 40 percent had similar effectsEB3 levels shrank in the AIS, and plasticity was restored.

Our study provides a completely different explanation for why tau is toxicnot because it forms aggregates, but because it binds to cytoskeletal proteins important for plasticity and makes rigid structures, Gan, who has since moved to Weill Cornell Medicine, New York, told Alzforum. This is an unexpected aspect of tau pathology. Gan plans to test whether this is true in other FTD mutations, and wonders about tau-induced hyperexcitability in Alzheimers disease, in which tau is not mutated.

This study provides an important demonstration of the utility of human iPSC models to reveal changes in neuroplasticity that may lead to disruption of brain circuitry over the course of disease, wrote Stephen Haggarty, Massachusetts General Hospital, Boston, to Alzforum. [It] provides further validation of therapeutic strategies seeking to reduce expression of pathological forms of tau.

Not all tau mutations work in this manner. In the September 19 Stem Cell Reports, researchers led by Hideyuki Okano of Keio University, Tokyo, report a different effect of the R406W. This mutation lies outside the microtubule-binding domain, but has nevertheless been reported to impede tau binding to those intracellular rails. Also using patient-derived neurons, first author Mari Nakamura and colleagues found that R406W tau mislocalizes to dendrites, as was seen before in cell and animal overexpression models (Thies and Mandelkow, 2007; Jan 2011 news). There it disrupts mitochondrial transport and causes axonal degeneration.

In neither study do the cell models rely on overexpression of the mutant tau protein, thereby overcoming issues often inherent to artificially engineered systems, Haggarty wrote.Gwyneth Dickey Zakaib

Stem Cells May Be Able To Repair The Brain – Anti Aging News

Transplanted brain stems cells have survived without using anti-rejection drugs in mice by exploiting a feature of the immune system, findings may open new paths for stem cell transplants to help repair the brain.

Johns Hopkins Medicine research may have developed a way to transplant certain protective brain cells without the need for lifelong anti-rejection drugs, as published in the journal Brain; the approach selectively circumvents responses from the immune system against foreign cells to allow the transplanted cells to survive and thrive to protect brain tissues long after stopping immunosuppressive drugs.

"Because these conditions are initiated by a mutation causing dysfunction in one type of cell, they present a good target for cell therapies, which involve transplanting healthy cells or cells engineered to not have a condition to take over for the diseased, damaged or missing cells," says Piotr Walczak, M.D., Ph.D., associate professor of radiology and radiological science at the Johns Hopkins University School of Medicine.

The researchers are working on developing ways to stop the immune system responses without side effects, and investigated ways to manipulate T cells which are the immune systems infection fighting force that attack foreign invaders, specifically focussing on a series of costimulatory signals that T cells must encounter in order to begin attack.

"These signals are in place to help ensure these immune system cells do not go rogue, attacking the body's own healthy tissues," says Gerald Brandacher, M.D., professor of plastic and reconstructive surgery and scientific director of the Vascularized Composite Allotransplantation Research Laboratory at the Johns Hopkins University School of Medicine and co-author of this study.

To exploit natural tendencies of these costimulatory signals that train the immune system to accept the transplanted cells as being part of self the researchers used CTLA4-lg and anti-CD154 antibodies to keep the T cells from beginning an attack by blocking signals.

Protective glial cells that produce myelin sheath that surrounds neurons that were genetically engineered to glow were injected into mice brains so they could be studied. Glial cells were transplanted into three types of mice: those engineered to not for glial cells that create myelin sheath; normal mice; and those engineered not to be able to mount an immune response.

Antibodies were used to block an immune response, stopping treatment after six days, and specialized cameras were used to detect the glowing cells and pictures of the mice brains to look for the presence or absence of the transplanted cells. Cells transplanted into control mice without antibody treatment began to die off immediately and was no longer detected after 21 days; while those receiving antibody treatment maintained significant levels of transplanted cells for over 203 days even in the absence of treatment.

"The fact that any glow remained showed us that cells had survived transplantation, even long after stopping the treatment," says Shen Li, M.D., lead author of the study. "We interpret this result as a success in selectively blocking the immune system's T cells from killing the transplanted cells."

To see whether the transplanted glial cells survived well enough to create the myelin sheath key structural differences were looked at between mice brains with and without thriving glial cells using MRI imaging; cells in the treated animals were found to be populating the appropriate parts of the brain. Results confirm the transplanted cells were able to thrive and assume normal function to protect neurons.

Although results are preliminary the cells were delivered to thrive in a localized portion of the mouse brain. Researchers hope to combine findings with studies on cell delivery methods to the brain in the future to help repair the brain more globally.

MS News that Caught My Eye: Stem Cell Transplants, Remyelination Agent, Tecfidera Study, Plasma Exchange and Tysabri-linked PML – Multiple Sclerosis…

Its been a big week for interesting stories, as the annual meeting of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) has just concluded. The conference offered much to engage healthcare professionals and researchers, but the following are some presentations that appealed to me as a multiple sclerosis (MS) patient.

The debate continued over the risks versus the rewards of stem cell transplants. Joachim Burman, MD, PhD, a researcher at Uppsala University in Sweden, made the case as to why autologous hematopoietic stem cell transplantation may be the most effective MS treatment so far, and why it should be made widely available. A single administration can yield prolonged benefits, and most patients achieve no evidence of disease activity status for at least five years. But safety concerns exist, and the lack of control groups tempers the positive results in studies.

Stem cell therapy, or stem cell transplant, is an emerging yet controversial treatment approach for multiple sclerosis (MS). While some data uphold it as one of the most efficacious MS treatments, to date there have been no controlled studies comparing it to conventional medicines and providing more robust evidence regarding its safety and clinical benefit.

Under the topic HSCT and stem cell treatment in MS,a group of researchers discussed the promise and current challenges of stem cell transplant at the 35thCongress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), being held Sept. 1113 in Stockholm.

As those of us who have multiple sclerosis know, finding a way to repair the damage to the myelin that covers our nerves would be like discovering the Holy Grail. This research, which looked into whether a potential remyelination agent is safe and might provide some repair, gives some hope.

Treatment with a potential remyelinating agent called liothyronine was safe and well-tolerated by people with multiple sclerosis (MS) in a Phase 1b trial. Preliminary results also suggested benefits in cognition, motor function, and fatigue.

The study, A Phase 1b, open-label study to evaluate the safety and tolerability of the putative remyelinating agent, liothyronine, in individuals with multiple sclerosis, was presented today at the 35thCongress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), by Scott D. Newsome, professor of neurology at Johns Hopkins University School of Medicine.

Out of 618 RRMS patients followed for 10 years, 192 of them were on continuous Tecfidera (dimethyl fumarate) twice daily treatment throughout that time, and many reported that the disease-modifying therapy (DMT) had helped them. Just over half of these patients remained relapse-free, and 64 percent had no signs of confirmed disability progression over that period. In a separate presentation, researchers found that the DMTs Tysabri (natalizumab) and Lemtrada (alemtuzumab) were better at reducing the annualized relapse rate than Tecfidera.

New 10-year data from the Phase 3 ENDORSE trial confirms the long-term benefits of Biogens Tecfiderafor patients with relapsing-remitting multiple sclerosis(RRMS), the most common form of this disease.

Real-world data from another study also showed Tecfidera to be superior to several other disease-modifying therapies for relapsing MS, namely Copaxone (glatiramer acetate), Aubagio(teriflunomide), andinterferon beta.

Treatment with Tysabri (natalizumab) carries the risk of triggering the often fatal brain infection progressive multifocal leukoencephalopathy (PML). Several treatments have been tried to attack PML, one of which is a type of blood cleansing called PLEX. It was hoped that PLEX would quickly clear Tysabri from the blood, and in doing so, would improve PML survival rates. Unfortunately, this study reports that two years after PML was detected the survival rate of patients treated with PLEX was no different than patients who had not received the treatment.

Use of plasma exchange (PLEX) is not effective for treating progressive multifocal leukoencephalopathy (PML), a dangerous brain infection that has been associated with using the multiple sclerosis (MS) medicine Tysabri (natalizumab), a real-world study contends.

The findings highlight the importance of closely monitoring Tysabri users to detect PML as early as possible.

Tiny ‘envelopes’ show promise for sun-damaged skin repair – Futurity: Research News

Exosomes harvested from human skin cells are more effective at repairing sun-damaged skin cells in mice than popular retinol or stem cell-based treatments currently in use, according to a new proof-of-concept study.

Additionally, needle-free injections can deliver the nanometer-sized exosomes to the target cells.

Exosomes are tiny sacs (30150 nanometers across) that cells excrete and take up. They can transfer DNA, RNA, or proteins from cell to cell, affecting the function of the recipient cell. In the regenerative medicine field, researchers are testing exosomes as carriers of stem cell-based treatments for diseases ranging from heart disease to respiratory disorders.

Think of an exosome as an envelope with instructions insidelike one cell mailing a letter to another cell and telling it what to do, says corresponding author Ke Cheng, professor of molecular biomedical sciences at North Carolina State University and professor in the universitys joint biomedical engineering department with the University of North Carolina at Chapel Hill. In this case, the envelope contains microRNA, non-coding RNA that instructs the recipient cell to produce more collagen.

To test whether exosomes could be effective for sun-damaged skin repair, the researchers first grew and harvested exosomes from skin cells. They used commercially available human dermal fibroblast cells, expanding them in a suspension culture that allowed the cells to adhere to one another, forming spheroids. The spheroids then excreted exosomes into the media.

These 3D structures generate more procollagenmore potent exosomesthan you get with 2D cell expansion, says Cheng.

In a mouse model, Cheng tested the 3D spheroid-grown exosomes against three other treatments: retinoid cream; 2D-grown exosomes; and bone marrow derived mesenchymal stem cells (MSCs) exosomes, a popular stem cell-based anti-aging treatment currently in use.

The team compared improvements in skin thickness and collagen production after treatment. They found that skin thickness in 3D exosome treated mice was 20% better than in the untreated and 5% better than in the MSC-treated mouse. Additionally, they found 30% more collagen production in skin treated with the 3D exosomes than in the MSC treated skin, which was the second most effective treatment.

I think this study shows the potential for 3D exosomes to be used in anti-aging skin treatments, says Cheng. There are two major benefits to exosome treatments over conventional treatments: one, you can use donor skin cells from anyone to grow and harvest these exosomesthey arent cells, so you dont run the risk of rejection. And two, the treatment can be administered without needlesexosomes are small enough to be able to penetrate the skin via pressure, or jet injection methods.

Our hope is that eventually people may be able to bank skin samples and come back to them, or use donor exosome treatments that they can administer themselves. We believe that this work is an important step toward potentiating future human clinical trials in the prevention and treatment of cutaneous aging.

The work appears in ACS Nano.

The National Institutes of Health and the American Heart Association supported the research, in part.
