Abstract

In our recent article Hörmann and coworkers have reported a role for epithelial cell-intrinsic TLR2 signaling for proliferation and renewal of the small intestinal epithelium. In this study, MyD88 and TRIF expression in the small intestine were affected by gut microbiota. Here, we report that in contrast to TLR2 and its co-receptor TLR1, TLR5 transcripts are not changed by presence of gut microbiota nor regulated through TLR2 or TLR4. Similar to TLR2 also TLR5 depends on MyD88 and TRIF adaptors. Our results indicate that TLR adaptor molecules could be determinants of TLR expression in the small intestine.
