The counts of IL-23+ cells and IL-17+ cells in each 200x field of view in PF lesions were 42.67 ± 5.812 and 21.33 ± 4.485, respectively (see Supplementary Figure in the Supplementary Material available online at http://dx.doi.org/10.1155/2014/463928), where we found a statistically significant decrease in number compared to PV (P < 0.05). The gene discussed is IL17A; the disease is pemphigus foliaceus.
