2021-01-21 · 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.

Katrin I Andreasson Prostaglandin E2 (PGE2), a potent lipid signaling molecule, modulates inflammatory responses through activation of downstream G-protein coupled EP1-4 receptors.

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. 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.

Which makes them valid wound relievers.

EP2 and EP3 are dominantly expressed in ventral spinal cord in neurons and astrocytes, and activation of these receptor subtypes individually or in combination also rescued motor neurons. 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 says.

Andreasson is clear in noting the long research path that lies ahead. The experimental drugs used in the study to block PGE2-EP2 binding, for example, are not at all ready for human clinical use.

Author information: (1)Department of Neurology and Neurological Sciences, Stanford University School of Medicine, Stanford, CA 94305, USA. PGE2 exerts its downstream effects by signaling through a class of four distinct G-protein-coupled E-prostanoid receptors (EP1-EP4) that have divergent effects on cAMP.
