Cytokine networks in Paneth cell regulation. (PubMed, Mucosal Immunol)
Cytokines such as Interferons (IFNs), Interleukin (IL)-9, IL-13, IL-17, IL-22, and tumor necrosis factor (TNF) influence diverse aspects of Paneth cell biology and, in turn, intestinal tissue homeostasis. In this review, we synthesize current knowledge of cytokine-mediated regulation of Paneth cells, explore the emerging role of Paneth cell phenotyping as predictive in intestinal disease outcome, and conclude with key unanswered questions that define future research directions in the field.
