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. 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. Advertisement. Andreasson and her colleagues also confirmed significant increases of PGE2 levels in the blood and brains of old mice.
Proceedings of the National 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. PGE2 has four separate counterpart receptors, designated EP1 through EP4, each of which sets in motion a different set of activities inside cells on binding to PGE2. Andreasson’s team used a mouse model of stroke to show that activating one of these receptors, EP4, after a traumatic brain event such as a stroke can be very beneficial. Katrin I Andreasson.

“It’s a double-whammy—a positive feedback loop,” Andreasson says. 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. Stroke is the leading cause of disability and fifth leading cause of mortality in the United States. Previous studies demonstrate a highly protective effect of inhibiting cyclooxygenase-2 (COX-2) after stroke, indicating that downstream PGE2 signaling pathways cause cerebral ischemic injury.

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
Andreasson’s team tried two experimental drugs that blocked the PGE2-EP2 link. This caused aged myeloid cells to behave just like younger versions, reversing their inflammatory activities in lab
