描述 | GPR84 is a medium chain fatty acid (MCFA) receptor, with capric acid (a 10-carbon chain fatty acid) being the most potent ligand. It is highly expressed in the cells of myeloid lineage that constitute the innate immune system, including monocytes, macrophages, and neutrophils in the periphery and microglia in the brain. GPR84 Antagonist 8 is a selective GPR84 antagonist from the patent literature (Galapagos NV Company, US 2013/0165437 A1). As a GPCR antagonist, GPR84 Antagonist 8 dose-dependently inhibited the action of 6-OAU in decreasing cAMP production in GPR84-CHO cells. Blockade of GPR84 activation by pre-treatment with GPR84 Antagonist 8 at 10μM for 30min before adding 1μM GPR84 agonist 6-OAU in LPS pre-treated BMDMs, reduced the expression of TNFα, IL-6, IL12b, CCL2, CCL5, and CXCL1, as well as partially blocked the phosphorylation of AKT and ERK induced by 6-OAU. GPR84 Antagonist 8 at 10μM could antagonize the migration, bacterial adhesion, and phagocytosis promoted by 6-OAU mediated—GPR84 activation in macrophages. Pretreatment with GPR84 Antagonist 8 at 10μM for 1h blocked 6-OAU induced U937 cell migration. |
