Moreover, the levels of cytokines involved in psoriasis and, respectively, characteristic of IL-17A–producing T cells and Treg cells (IL-17A and IL-10) were measured in the culture supernatants of HS, PS, PS+T, and PS+T+EPA using independent ELISA assays to characterize the T cell profile of each condition (Fig. 4B). This evidence concerns the gene IL10 and psoriasis.
