One immune switch may help drive aging across the body

What the research found
Study (mice and human cells). Stanford Medicine researchers report in Science that tissue-resident macrophages lose the ability to clear senescent neutrophils with age. Blocking the PGE2 receptor EP2 on those macrophages in mice restored cleanup and left older animals leaner, stronger, and sharper across brain, heart, muscle, liver, and other organs. Human liver-cell data showed similar neutrophil buildup and EP2 activity with age. This is laboratory and observational tissue work, not a clinic protocol. No approved EP2-selective drug exists; NSAIDs that broadly lower prostaglandins are not a longevity prescription.
Evidence level: Animal study. Results in animals or cells often don't carry over to people.
