摘要：We here found that intestinal epithelial Paneth cells secrete FABP4, adipsin and adiponectin in both mice and human. Deletion of Paneth cell results in the decrease of FABP4, adipsin and adiponectin not only in intestinal crypt cells but also in sera, suggesting that they may influence the state of the whole body. We also demonstrate that expression of FABP4, adipsin and adiponectin may be modulated by specific gut microbiota. In germ-free (GF) mice, the expression of FABP4, adipsin and adiponectin were lower or difficult to be detected. Feces transplantation promoted the expression of FABP4, adipsin and adiponectin in gut epithelial Paneth cells. We have found that Lactobacillu s NK6 colony, which has the highest similarity with Lactobacillus taiwanensis strain BCRC 17755, may induce the expression of FABP4, adipsin and adiponectin through TRAF2 and TRAF6 ubiquitination mediated NF-κB signaling. Taken together, our findings set up a novel mechanism for FABP4, adipsin and adiponectin through gut microbiota mediating expression in gut Paneth cells.
