Episode Description
Zombie cells sound like a metaphor, but cellular senescence is real biology that can quietly damage tissue through chronic inflammation and toxic secretions. We trace how senolytics work at the molecular level, why dosing has to be pulsed, and why the future looks more like precision maintenance than a magic anti-aging pill.
• what cellular senescence is and why it starts as tumor protection
• how senescent cells resist apoptosis through BCL2 family survival networks
• how SASP drives extracellular matrix breakdown, inflammaging, and nearby cell senescence
• how dasatinib plus quercetin targets senescent cells and why quercetin can act as a pro-oxidant via the Fenton reaction
• why fisetin dosing is pharmacologic and why “food sources” and many supplements miss the mark
• why senolytics use hit-and-run pulses and the real risks of continuous pathway inhibition
• what mouse data in diabetic kidney disease suggests about fibrosis and geroprotective factors
• what the Mayo Clinic trial in healthy women reveals about a senescence threshold and who is likely to benefit
• why a knee osteoarthritis injection failed clinically even if it hit the biological target
• why localized delivery is winning in areas like diabetic macular edema and dermatology
Keep learning, keep questioning, and we'll catch you on the next deep dive.
