PANoptosis in the Aging of the Heart
The review spotlights PANoptosis—a hybrid programmed cell‑death process that fuses pyroptosis, apoptosis and necroptosis—and its emerging relevance to cardiac aging. It details how the PANoptosome complex accelerates cardiomyocyte loss, fibrosis and chronic inflammation, key drivers of age‑related heart decline. Preclinical work using gene‑editing, RNA‑interference and novel delivery platforms shows that modulating PANoptosis can preserve cardiac function. By mapping molecular pathways and intervention points, the article lays groundwork for next‑generation therapies targeting heart aging.
