IL6 and psoriasis: IL-6 was secreted at low levels with slightly more in psoriasis plaque T cells (0.09 versus 0.05 ng/ml, p = 0.18), while the soluble IL-1 receptor α (0.36 in ACD versus 0.28 ng/ml in psoriasis, p = 0.18) and TNF-α (4.5 versus 0.3 ng/ml, p = 0.18) were secreted in higher amounts by ACD T cells.
