Effect of NTI-164 and CBD on the expression of inflammatory markers in BV-2 microglia cells exposed to excipient + IL-1β and IFNγ (inflammation, yellow) and inflammation + NTI164 (+NTI164, grey hatched) and inflammation + CBD (+CBD, black hatched) in (A,B) inducible-nitric oxide synthase (iNOS), (C) arginase-1 (Arg1) and (D,E) expression of cyclo-oxygenase-2 (COX2) protein normalised to DAPI-positive cell number in the control group (PBS only). Scale bar = 100 µM. Mean ± SEM, n = 8–9. One-way ANOVA, with post hoc test as indicated on the graphs. Significance set at *, p < 0.05; **, p < 0.01; ***, p < 0.001. ns = p > 0.05.
