⁠Zombie Cells: The Silent Drivers of Aging, Inflammation, and Disease l Ep #378

About this video

This solo explainer introduces senescent, or zombie, cells: cells that have stopped dividing yet resist death and secrete inflammatory signals known as the SASP. Niddam explains how DNA damage, oxidative stress, and telomere shortening create them, how lifestyle factors she lists, including poor sleep, smoking, overeating, and high-glycemic diets, can increase their burden, and how their accumulation is linked in the literature she reviews to inflammaging and age-related disease. She stresses that senescent cells also aid wound healing and tumor suppression, so the goal she advocates is reducing lingering excess, not elimination. She reviews investigational senolytic drugs, senomorphic agents, and lifestyle strategies, and discusses an experimental senescence-targeting peptide as an advanced, practitioner-only topic.

Key takeaways

• Aim to lower excess senescent-cell burden, not to wipe senescent cells out
• Protect sleep, activity, and diet quality as first-line ways to limit senescence drivers
• Distinguish senolytics that clear cells from senomorphics that quiet their secretions
• Treat senescence-targeting drugs and peptides as investigational until human evidence matures
