The same group undertook an unbiased proteomic screen to identify regenerating islet-derived 3- (REG3), a C-type lectin secreted by small intestinal Paneth cells, as a novel diagnostic and prognostic marker in acute lower GI GVHD. The function for these cells is secretion of anti-bacterial proteins into the crypt lumen, thereby providing protection for the stem cells which line the crypt walls.

Cells were cotransfected with TR and/or KLF4 expression vectors and treated 100 nmol/L thyroid hormone (T3). Previous studies found that *A. muciniphila* was significantly increased in IFN-deficient mice, and the restoration of IFN levels could reduce *A. muciniphila* abundance.40 IFN can induce the secretion of antimicrobial proteins from Paneth cells through Irgm1, a downstream molecule in its signalling cascade. Pancreas. The Brunner glands, which empty into the intestinal glands, secrete an alkaline fluid composed of mucin, which exerts a physiologic anti-acid function by coating the duodenal epithelium, therefore protecting it from the acid chyme The content of Paneth cell granules is delivered to the gut lumen by a process of merocrine secretion whereby the membrane of an individual granule fuses with the apical cell surface membrane. Low-level regulatory T-cell activity is essential for functional type-2 effector immunity to expel gastrointestinal helminths. Paneth-cell-specific deletion of Xbp1 in D6-cre;Xbp1 fl/fl (Xbp1 PC) mice resulted in autophagy activation (Fig. Paneth cells are tightly nested between ISCs in the crypt base; they act as anti-microbial defensive cells, while also producing supportive growth factors for neighboring ISCs .
