Scientists find how “zombie” cells fuel inflammation as we age
Source: ScienceDaily
What the research found
Study (mice and cells). Peter Adams, João Passos, Hélène Martini and colleagues report in Nature that senescent cells raise mitochondrial acetyl-CoA, loosening DNA packaging around SASP inflammatory genes, while leaky mitochondrial DNA/RNA supplies the immune signal to switch those genes on. Blocking acetyl-CoA transport with CTPI-2 reduced inflammation and improved healthspan in aging mice even though the leak signals remained. Mouse work is not a human senolytic protocol. Educational cell-aging notes, not medical advice.
Evidence level: Animal study. Results in animals or cells often don't carry over to people.
