2. Senolytics: The Science of Killing Zombie Cells

Senolytics represent a groundbreaking class of drugs that target and eliminate senescent, or “zombie,” cells—damaged cells that linger in the body and promote aging and chronic disease. By clearing these harmful cells, senolytics aim to restore tissue function, reduce inflammation, and slow age-related decline. Early studies have shown promising results in improving healthspan and alleviating symptoms of age-associated disorders. This transformative approach is reshaping anti-aging therapies, as highlighted by ongoing research at institutions like the Mayo Clinic.
