One of the first trials examining plasma exchange for anti-aging in humans, published Tuesday in the journal Aging Cell, offers early evidence that it may be able to slow the biological breakdown that comes with age, even in otherwise healthy people. The small study of 42 participants, with an average age of 65, found that those who got plasma exchange therapy over the course of a few months had lower concentrations in their blood of the biological compounds that accumulate with age, compared with a control group. The trial was sponsored by Circulate Health, a plasma exchange startup, and coauthored by Dr. Verdin, a company co-founder and head of the scientific advisory board.
