Monocytes differentiated with IL-15 support Th17 and Th1 responses to wheat gliadin: Implications for celiac disease
چکیده انگلیسی

Interleukin (IL)-15 contributes to the immunopathogenesis of Celiac disease (CD). However, it is not clear how IL-15 affects APC that shape adaptive immune responses to the dietary antigen, gliadin. Using PBMC from healthy individuals, we show that monocytes differentiated with IL-15 (IL15-DC) produced IL-1β, IL-6, IL-15, IL-23, TNFα and CCL20 in response to pepsin-trypsin digested gliadin (PTG) and activated contact-dependent Th17 and Th1 responses from autologous CD4+ T cells. Lower concentrations of IL-15 augmented IFNγ responses to PTG in PBMC from CD patients compared to controls. Thus, IL-15 supports Th17 and Th1 responses to a dietary antigen that is normally well-tolerated in healthy individuals by generating IL15-DC. These potentially pathogenic immune responses may result in CD patients and not healthy individuals as a consequence of IL-15 hypersensitivity. Therefore, genetic and/or environmental factors that control IL-15 expression and responsiveness in the intestine likely participate in the pathogenesis of CD.
