IL17F and psoriasis: Using RNA microarray and Ingenuity Pathway analysis, we found that several interesting pathways were affected by RSV, like increased RXR expression and decreased expression of IL-17 dependent pathways as well as decreased expression of IL-17A, IL-17F and IL-19, and propose that these changes might be mediators of the positive effects observed on the psoriasis-like skin inflammation model used in our study.
