From: Selective proliferative response of microglia to alternative polarization signals
Expression of cell cycle and M2 polarization genes in peritoneal macrophages following IL-4 treatment in vivo. The expression of genes related with a cell proliferation (Ki67, Cdk1, and CcnB2) and b M2 alternative polarization (Arg1, Fizz1, and Ym1) was analyzed by real-time PCR in peritoneal macrophages isolated from mice treated i.p. with vehicle (veh) or 5 μg IL-4 for 24 h. Data sets for each gene were calculated using the 2-ddCt method with respect to the mean value of the vehicle group. Bars represent mean values ± SEM (n = 2–6). Student’s unpaired t test, *p < 0.05; **p < 0.01; ***p < 0.001 versus veh
