Selfish genetic elements amplify inflammation and age-related diseases

Aging affects every living organism, but the molecular processes that contribute to aging remain a subject of debate. While many things contribute to the aging process, one common theme in animal aging is inflammation—and this may be amplified by a class of selfish genetic elements. The human genome is littered with selfish genetic elements—repetitive elements that do not seem to benefit their hosts, but instead seek only to propagate themselves by inserting new copies into their host genomes. A class of selfish genetic elements called LINE1 retrotransposons are the most prevalent retrotransposon selfish genetic elements found in humans; approximately 20 percent of both human and mice genomes are composed of LINE1s. Researchers have long suspected that LINE1s contribute to cancer and genomic instability. However, the harm inflicted by these genomic parasites reaches much further than researchers had at first thought. In a paper in the journal Cell Metabolism, researchers from the University of Rochester, including Vera Gorbunova, the Doris Johns Cherry professor of biology, and Andrei Seluanov, professor of biology, show that LINE1 retrotransposons become more active with age and may cause age-related diseases by triggering inflammation. By understanding the impacts of retrotransposons, researchers can better recognize the processes by which cells age and how to combat the deleterious effects of aging.

Capricor Therapeutics Announces Collaboration with the National Institutes of Health for Clinical Trial of Novel Exosome-Based Multivalent Vaccine

Capricor Therapeutics | January 24, 2024

Capricor Therapeutics a biotechnology company developing transformative cell and exosome-based therapeutics for the treatment and prevention of rare diseases, today announced that Capricor’s proprietary StealthX™ exosome-based multivalent vaccine (StealthX™ vaccine) for the prevention of SARS-CoV-2 has been selected to be part of Project NextGen, an initiative by the U.S. Department of Health and Human Services to advance a pipeline of new, innovative vaccines providing broader and more durable protection for COVID-19. As part of Project NextGen, the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, will conduct a Phase 1 clinical study with Capricor’s StealthX™ vaccine, subject to regulatory approval. NIAID's Division of Microbiology and Infectious Diseases (DMID) would oversee the study. “We are extremely pleased with the external support from the NIH, which highlights the clinical potential of our StealthX™ exosome platform technology and provides non-dilutive support for the advancement of our vaccine candidate,” said Linda Marbán, Ph.D., Capricor’s chief executive officer. “Our proprietary vaccine is multivalent, delivering both the highly mutagenic S protein (Spike) and the more stable N protein (Nucleocapsid) which potentially may offer broader and longer lasting immunity against SARS-CoV-2. We view the NIH SARS-CoV-2 project as the first clinical step towards development of a next generation vaccine platform that may be extended to other infectious diseases. Our platform is designed to combine the speed of response of an mRNA vaccine with the potential efficacy of a protein vaccine. Further, our StealthX™ vaccine is free of both adjuvant and lipid nanoparticles and in preclinical studies has generated a strong immune response at low doses. We believe our StealthX™ vaccine may offer a clinically meaningful alternative for highly mutating or novel infectious agents.” Dr. Marbán continued, “This is the opportunity we have been waiting for as it allows the exosome technology to be brought into the clinic as we continue to focus our resources on CAP-1002 for the treatment of Duchenne muscular dystrophy. Beyond SARS-CoV-2, we look forward to exploring the potential therapeutic utility of this platform, and more broadly, expanding our pipeline into therapeutics and future partnership opportunities.” About Capricor’s StealthX™ Vaccine The StealthX™ vaccine is a proprietary vaccine developed internally by Capricor utilizing exosomes that were engineered to express either spike or nucleocapsid proteins on the surface. Preclinical results from murine and rabbit models published in Microbiology Spectrum, showed the StealthX™ vaccine, resulted in robust antibody production, potent neutralizing antibodies, a strong T-cell response and a favorable safety profile. These effects were obtained with administration of only nanogram amounts of protein and without adjuvant or synthetic lipid nanoparticles (LNPs). Exosomes offer a new antigen delivery system that potentially could be utilized to rapidly generate multivalent protein-based vaccines. Exosomes, first identified as extracellular vesicles, are small vesicles enriched in specific subsets of proteins, RNAs and lipids and responsible for cell-to-cell communication. About Capricor Therapeutics Capricor Therapeutics, Inc. is a biotechnology company focused on the development of transformative cell and exosome-based therapeutics for the treatment and prevention of rare diseases. Capricor’s lead candidate, CAP-1002, is an allogeneic cardiac-derived cell therapy currently in Phase 3 clinical development for treating Duchenne muscular dystrophy (DMD). Further, Capricor has entered into a partnership for the exclusive commercialization and distribution of CAP-1002 for DMD in the United States and Japan with Nippon Shinyaku Co., Ltd. (U.S. subsidiary: NS Pharma, Inc.), subject to regulatory approval. Capricor is also developing its exosome technology as a potential next-generation therapeutic platform. Our proprietary StealthX™ exosome platform has potential for a broad range of new therapeutic applications in the field of vaccinology as well as targeted oligonucleotide, protein and small molecule therapeutics to treat or prevent a variety of diseases.

Solvias to Perform Release Testing on World's First CRISPR-based Gene-Editing Therapy

Solvias | January 23, 2024

Solvias, a global provider of chemistry, manufacturing, and control (CMC) analytics, announced that it will perform analytical release testing services on the world's first CRISPR/Cas9 genome-edited cell therapy. The company has signed a long-term agreement with Vertex Pharmaceuticals for CASGEVY™ (exagamglogene autotemcel or exa-cel) which received U.S. Food & Drug Administration (FDA) approval for the treatment of sickle cell disease (SCD) in patients 12 years and older with recurrent vaso-occlusive crises. Solvias and Vertex Pharmaceuticals have worked together for several years to develop and validate test methods that are critical for the final release of patients' own edited cells, so that they can be delivered back to patients. The companies' collaboration included establishing the testing methods that will be scaled for commercializing CASGEVY. Solvias also has invested significantly in preparing one of its global facilities to support the commercial release work for this transformative therapy. Archie Cullen, Chief Executive Officer, Solvias, stated "Solvias is honored to be playing a critical role in delivering this breakthrough therapy to patients.
