KCa3.1 inhibition reverts GCM-induced microglia polarization. (a) RT-PCR on mRNAs of microglia treated with NCM or GCM in the absence (C) or presence of TRAM-34 (T, 2.5 μM), analyzed for the expression of M2-like (arg1, ym1, fizz1, cd163 and cd206) and M1-like (cd86, tnfα, inos, il1β and il6) related genes. Data are expressed as fold increase and are the mean±S.E.M.; *P<0.05 versus NCM; #P<0.05 versus GCM/C by two-way ANOVA and paired t-test for inos; N=8. (b) NCM- and GCM-treated microglia in the absence (C) or presence of TRAM-34 (T, 2.5 μM), stained with phalloidin (green) and Hoechst (blue). Scale bar: 20 μm. Form factor values (calculated as reported in the Materials and Methods section) are shown in the graph and are the mean±S.E.M., *P<0.05 versus NCM; #P<0.05 versus GCM/C by two-way ANOVA; N=4
