Figure 4From: Translocator protein (18 kDa) (TSPO) is expressed in reactive retinal microglia and modulates microglial inflammation and phagocytosis The TSPO agonist XBD173 reduces microglial migration and proliferation. (A) Scratch assay to mimic wound-healing in cultured BV-2 microglia treated with vehicle, 50 ng/ml LPS, 50 μM XBD173 or both. Microphotographs from scratched areas were quantified 8 h after treatment (B). Data show mean ± SEM (n = 5/group) *P <0.05 XBD173 versus control, *P <0.001 XBD173 + LPS versus LPS-treated cells. (C), CFSE-based proliferation assay of BV-2 microglial cells treated with vehicle, 100 ng/ml LPS, 50 μM XBD173 or 100 ng/ml LPS + 50 μM XBD173. The proliferation rate of BV-2 microglia was analyzed 24 hours after treatment using flow cytometry and a representative graph out of four repetitions is shown. CFSE, carboxyfluorescein diacetate succinimidyl ester; LPS, lipopolysaccharide; TSPO, translocator protein (18 kDa).Back to article page
