ML-193 effect on microglia immunal function.
By Anonymous on 09/21/2019

Species: Mouse
Cell Line/Tissue: Hippocampus

ML-193 was used to study the effect of receptor GPR-55 on release of prostaglandin E2 from hippocampal microglia. ML-193 triggered highly significant lowering of the prostaglandin release compared to control; however, difference between the effects of four tested doses was non-significant (see figure).

Soluble in DMSO, perfectly mixes with artificial cerebro-spinal fluid.
