Live Imaging of Paneth Cell Secretory Responses in Innate Immunity by Using Three-Dimensional Culture of Small Intestinal Epithelial Cells

2021年1月

Paneth cells, a lineage of small intestinal epithelial cells, secrete granules rich in antimicrobial peptides, α-defensins, in response to cholinergic agents and bacteria, and regulate the intestinal microbiota by killing enteric pathogens, while less killing commensal bacteria. In this Application Note, we introduce examples that clarify the mechanisms of α-defensin secretion by visualization and quanti cation of Paneth cell granule secretory responses ex vivo using enteroid, a three-dimensional culture system of small intestinal epithelial cells.
