A sizable portion of the chronic inflammation of aging is produced by the growing presence of senescent cells in tissues throughout the body. Senescent cells secrete a mix of pro-growth, pro-inflammatory signals (the senescence-associated secretory phenotype, SASP), useful when present in the short-term in the context of wound healing and suppression of cancer risk resulting from cell damage. When sustained over the long-term, however, this signaling becomes highly disruptive to tissue structure and functio…
