senescent cells BCL-W BCL-XL ABT-737 apoptosis hair-follicle stem cell proliferation tissue regeneration

TLDR Blocking specific proteins can help remove aging cells and might treat age-related diseases and promote hair growth.

The study "Directed elimination of senescent cells by inhibition of BCL-W and BCL-XL" demonstrated that inhibiting the proteins BCL-W and BCL-XL with the drug ABT-737 effectively induced apoptosis in senescent cells both in vitro and in vivo. This led to the elimination of senescent cells in the lungs and skin of mice, resulting in increased hair-follicle stem cell proliferation and improved tissue function. The findings suggested that targeting these anti-apoptotic proteins could be a promising strategy for treating age-related diseases and promoting tissue regeneration.

community Looks like a real cure to the root of baldness (DHT-induced senescence) was proven earlier this year

in Research/Science 742 upvotes 2 years ago

A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.
