On the other hand, in a recent study (Mruwat et al., unpublished), we have found that the production of inflammatory/allergic cytokines (IL-5, IL-13, IL-17 and INF-γ) by cultured human nasal polyps stimulated with super antigen, was associated with increased expression of sPLA2gX, and suppression of cPLA2α expression. This evidence concerns the gene IL17A and nasal cavity polyp.
