Article Snippet: The intestinal mucosa must balance tolerance to commensal microbes and luminal antigens with rapid detection of enteric pathogens in order to maintain homeostasis.. This balance is facilitated through the regulation of epithelial layer integrity by innate immune receptors.. Certain NOD-like receptors (NLRs) expressed in intestinal epithelial cells, including NLRC4 and NLRP9B, form inflammasomes that protect against pathogens by activating caspase-1 to cause extrusion of infected cells.

Article Snippet: In brief DOCK8-deficient patients and mice are prone to food allergy and oral anaphylaxis.. Here, Janssen et al. demonstrate that DOCK8 deficiency yields expanded mucosal mast cells and elevated circulating tryptase concentrations.. Loss of DOCK8 in T cells impairs Th17 and Treg cells, resulting in dysbiosis and unrestrained IL-4-driven mast cell expansion.
