Scientists reverse aging in blood stem cells by targeting lysosomal

“Researchers at the Icahn School of Medicine at Mount Sinai have discovered how to reverse aging in blood-forming stem cells in mice by correcting defects in the stem cell’s lysosomes. The breakthrough, published in Cell Stem Cell , identifies lysosomal hyperactivation and dysfunction as key drivers of stem cell aging and shows that restoring lysosomal slow degradation can revitalize aged stem cells and enhance their regenerative capacity.”

Just a very quick AI dive:

Therapies to restore low lysosomal activity and the functional decline of old [hematopoietic stem cells (HSCs)]) are an active area of research, including gene therapy, metabolic senescence>> modulators like nicotinamide riboside (NR), and dietary interventions like prolonged fasting. Specific treatments and medications being explored or used for conditions like [lysosomal storage diseases (LSDs)] or aging include enzyme replacement therapy (ERT), substrate reduction therapy (SRT), and the use of compounds like N-acetylcysteine (NAC).

If only we had access to the more advanced therapies.
