In contrast, the Th2 cytokines IL-4 (1.2 versus 0.2 ng/ml, p = 0.18), IL-5 (2.9 versus 1.2 ng/ml, p = 0.67), IL-9 (1.1 versus 0.5 ng/ml, p = 0.23), IL-10 (0.3 versus 0.2 ng/ml, p = 0.18), and IL-13 (5.3 versus 2.5 ng/ml, p = 0.96) showed a consistent trend of higher secretion in ACD as compared to psoriasis T cells. This evidence concerns the gene IL13 and psoriasis.
