Gene-based interventions to modify aging processes
This review examines 'partial reprogramming'—a technique that temporarily activates rejuvenation factors to reverse aging hallmarks in cells and tissues without turning them into cancer-prone stem cells. Early evidence suggests it can restore tissue function and …
Researchers developed a method to rejuvenate aging mesenchymal stem cells (MSCs) by temporarily expressing three genes via a non-integrating virus, then removing the virus. The rejuvenated cells showed extended lifespan, restored telomeres, and maintained their …
Chimeric antigen receptor (CAR)-T cell therapy has shown success in hematologic malignancies but remains limited in solid tumors due to poor persistence, migration, and tumor microenvironment-induced exhaustion. In an investigator-initiated trial in relapsed/refractory ovarian cancer, …
This study reveals that a key growth factor called IGF-1 is essential for the rejuvenating effects of young blood on aging brains. When old mice shared circulation with young mice, their brain blood vessels improved—but …
Researchers used specially designed lipid nanoparticles to deliver reprogramming genes (OSK) directly to liver cells in mice with fibrosis, successfully converting scarred cells back to a regenerative state. This proof-of-concept study suggests mRNA-based cellular rejuvenation …
This is a curated introductory post for r/longevity that distinguishes legitimate aging biology research from quackery, providing structured access to academic papers, presentations, and university labs studying the biology of aging. The post establishes the …
Researchers identified DMTF1, a transcription factor, as potentially therapeutic for reversing age-related decline in neural stem cell proliferation caused by telomere shortening. The mechanism involves DMTF1 regulating SWI/SNF chromatin complexes to activate E2F genes, a …
A 2026 study by Shenhar and Alon claims genetics determine 50–55% of human lifespan—roughly double previous estimates of 15–30%—by filtering out accidental deaths from twin data. The finding suggests aging is a genetically regulated process …
This review synthesizes evidence that activating Hedgehog signaling—a developmental pathway—may counteract hallmarks of aging like stem cell exhaustion and chronic inflammation across brain, liver, heart, and other tissues. While preclinical results are promising, the authors …
Researchers used a gene therapy technique to partially "reprogram" neurons that store memories in aged mice and Alzheimer's disease models, reversing signs of aging in those cells and restoring learning and memory to young-animal levels. …
This concept paper proposes a new approach to treating Alzheimer's, Parkinson's, and ALS by directly increasing production of OGT—an enzyme that regulates thousands of proteins—rather than using existing indirect methods. The authors suggest using antisense …
A study of 41 children with Morquio A, a rare genetic disorder affecting bone and organ development, found that allogeneic hematopoietic cell transplantation (essentially replacing diseased blood-forming cells with healthy donor cells) was safe and …
Researchers grew human pluripotent stem cells on circular patterns and watched them spontaneously organize into distinct midbrain and hindbrain regions—without being explicitly programmed to do so. This self-organizing system could help screen for birth defects …
Researchers identified 13 genes that are mutated in both amyotrophic lateral sclerosis (ALS) and Charcot-Marie-Tooth disease (CMT)—two otherwise distinct neurological disorders. This suggests that despite their clinical differences, these diseases may operate through overlapping molecular …
