Having isolated the role played by PGE2, Andreasson and her team then set out to see if there was a way to counteract its negative effects. They administered to mice two experimental compounds that can block the EP2 receptor and found it reversed the metabolic problems seen in older macrophages -- restoring their more youthful behaviour and preventing destructive inflammatory activity.

Having isolated the role played by PGE2, Andreasson and her team then set out to see if there was a way to counteract its negative effects. They administered to mice two experimental compounds that can block the EP2 receptor and found it reversed the metabolic problems seen in older macrophages — restoring their more youthful behaviour and preventing destructive inflammatory activity. Andreasson and her colleagues also confirmed significant increases of PGE2 levels in the blood and brains of old mice. “It’s a double-whammy — a positive feedback loop,” Andreasson said. The resulting exponential increase in PGE2-EP2 binding amps up intracellular processes associated with inflammation in the myeloid cells.

They administered to mice two experimental compounds that can block the EP2 receptor and found it reversed the metabolic problems seen in older macrophages -- restoring their more youthful behaviour and preventing destructive inflammatory activity. Once PGE2 binds to EP2 it creates inflammation. According to the press release; “Andreasson’s team cultured macrophages, a class of myeloid cells situated in tissues throughout the body, from people older than 65 and compared them with macrophages from people younger than 35. They also looked at macrophages of young versus old mice Andreasson and his colleagues also confirmed significant increases in PGE2 levels in the blood and brains of old mice. It’s a double whammy – a positive feedback loop. “ Katrin Andreasson, MD, lead author of the study 2021-01-20 · The hormone, prostaglandin E2 (PGE2), Having isolated the role played by PGE2, Andreasson and her team then set out to see if there was a way to counteract its negative effects.
