Additionally, we found that some IL-1β-induced iNKT17 cells co-produce IFN-γ, arguing in favour of conversion of iNKT cells secreting IFN-γ into iNKT17 cells and suggesting that iNKT cells from T1D patients are likely to be more prone to be converted to IL-17-producing cells in the presence of appropriate inflammatoty cytokines. The gene discussed is IL17A; the disease is type 1 diabetes mellitus.
