Quantification of RORγ and FoxP3 staining in FIV infected and control cats. Mean fluorescence intensity of FoxP3 and RORγ, which label Treg and Th17 cells, respectively, were measured in both control and infected cats. Values are bracketed by standard error of the mean. Control (n = 9) versus infected (n = 11) samples were evaluated. P values < 0.05 were considered significant.
