Figure 6. Oxytocin suppresses microglial reactivity in vitro.
(A) Microglial MHC class II expression is up-regulated following a 24 hour LPS challenge (1µg/mL). Pre-incubation with the high dose (1 µM) but not the low dose (0.1 µM) OT attenuates LPS-stimulated MHC class II expression, however this effect is blocked by co-incubation with OTA (1 µM), n = 7 per treatment condition. (B) MHC Class II expression was measured on total CD11b+ cells as gated above. Graph reflects fold change of LPS alone or LPS+OT stimulation. * indicates a statistically significant difference between indicated groups, (P > 0.05).
