Description
We report that Klebsiella pneumoniae promote Th1 cell induction in colon. To examine the influence of Klebsiella on colonic epithelial cells (ECs) and lamina propria CD11c+ dendritic cells (DCs), we performed RNA seq on them. Germ free mice were orally inoculated with Kp-2H7 or BAA-2552 and total RNA was isolated from colonic ECs and DCs 1 week after inoculation. Furthermore, we examined the involvement of TLRs in induction of Th1 cells using Myd88 KO, Trif KO, Myd88/Trif DKO mice. These deficient germ free mice were orally inoculated with Kp-2H7 and total RNA was isolated from colonic ECs 3 weeks after inoculation. Overall design: The gene expression of colonic ECs and DCs isolated from germ free mice, and GF mice inoculated with Kp-2H7 or BAA-2552, and colonic ECs isolated from GF Myd88 KO, Trif KO or Myd88/Trif DKO mice inoculated with Kp-2H7.
