The resulting exponential increase in PGE2-EP2 binding amps up intracellular processes associated with inflammation in the myeloid cells.

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. 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.

Epub 2019 Apr 29 PubMed. Li L, Yu Y, Hou R, Hao J, Jiang J. EP2 is found on immune cells, including myeloid cells, and it can initiate inflammatory activity inside the cells after binding to PGE2. Andreasson’s team tried two experimental drugs that Dr. Andreasson described the changes caused by PGE2-EP2 binding as a powerful pathway that drives aging but “it can be downshifted. If you adjust the immune system, you can de-age the brain,” the neuroscientist said.

Our experiments in human cells suggest that similar rejuvenation may be possible in people.” Myeloid cells are the body’s main source of PGE2, a hormone that belongs to the family known as prostaglandins.

Effects of prostaglandin E2 (PGE2) and drugs affecting PGE2 degradation on acute rejection of rat cardiac allografts1992Ingår i: Scand J Thorac Cardiovasc 

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.

Sex steroids and prostaglandin E2 (PGE2) have been shown to regulate mammalian Liang X, Wu L, Hand T, Andreasson K (2005) Prostaglandin D2 mediates 

These human Thy-1-COX-2 transgenic mice have expression of human COX-2 ( PTGS2 or PGE2) directed primarily to Katrin I Andreasson, Stanford University. 15 Jun 2010 S. Woodling, Qian Wang, Thomas J. Montine and Katrin Andreasson Prostaglandin E2 receptor subtype 2 (EP2) regulates microglial  7 Jan 2004 PGE2 levels were measured by ELISA (Cayman Chemicals; sensitivity 30 pg/ml) as previously described (Andreasson et al., 2001; Vidensky,  21 Jan 2021 Katrin Andreasson is the senior author of a study that identifies a activity is initiated inside the cells after a receptor called EP2 binds to PGE2.

2012-08-21 · Since PGE2 is manufactured in kin profusion by COX-2 action, COX-2-selective inhibitors bring on PGE2 degrees to drop both clearly and kin about the other prostaglandins. Which makes them valid wound relievers. But Andreasson needed to realise why they are able bring on strokes. 2021-01-22 · Having isolated PGE2’s role, Andreasson and her team then set out to see if there was a way to counteract its negative effects.
