GPR84 gene exhibits high expression in human polymorphonuclear leukocytes (PMNs) and macrophages, 6-OAU acts on proinflammatory function by activitating GPR84.
6-OAU (0.01 nM-0.1 mM; 1 h) activates human GPR84 in the presence of Gqi5 chimera with an EC50 value of 105 nM in HEK293 cells.
6-OAU (0, 6.25, 200 μM; 30 min) stimulates [S]GTP binding, accumulates phosphoinositides, and induces GPR84-EGFP internalization in a GPR84-dependent manner.
6-OAU (1 nM-1 mM; 1 h) provokes chemotaxis of PMNs in a concentration-dependent manner with an EC50 value of 318 nM.
6-OAU (0-10 μM; 4 h) increases the secretion of IL-8 from LPS-stimulated PMNs.
6-OAU (0-0.4 μM; 16 h) also amplifies TNF-α production from U937 macrophages.
6-OAU (2 μM; 4 h) decreases ERK phosphorylation and MCP-1 protein expression, (2 μM; 48 h) decreases MCP-1 secretion in macrophages .
6-OAU (2 μM; 24 h) reduces ROS production during B. abortus infection in RAW264.7 cells.
6-OAU (2 μM; 0, 30, and 60 min) inhibits adhesion and Brucella uptake in RAW264.7 cells and (2 μM; 30 min) shows anti-infection against Brucella and Salmonella infection.
