Project description:Paneth cells originate in the stem cell region near the bottom of the gland and release a large number of secretory granules containing antimicrobials. The antimicrobial-rich granules are discharged into the crypt lumen and prevent microbial invasion of the crypt and defend the gland stem cells from microbial damage. We examined the global gene expression profiles in crypt IECs using the Clariom S sDNA array. We analyzed mRNA panels of antimicrobial peptides (AMPs) produced in CSN8ΔIEC and CSN8fl/fl mice.
