We recently showed that the immunopathological sequelae in Campylobacter jejuni-infected mice were due to Toll-like receptor (TLR)-4 dependent immune responses induced by bacterial lipooligosaccharide (LOS). Information regarding the molecular mechanisms underlying Campylobacter coli-host interactions are scarce, however. Therefore, we analyzed C. coli-induced campylobacteriosis in secondary abiotic IL-10-/- mice with and without TLR4. Mice were infected perorally with a human C. coli isolate or with a murine commensal Escherichia coli as apathogenic, non-invasive control. Independent from TLR4, C. coli and E. coli stably colonized the gastrointestinal tract, but only C. coli induced clinical signs of campylobacteriosis. TLR4-/- IL-10-/- mice, however, displayed less frequently fecal blood and less distinct histopathological and apoptotic sequelae in the colon versus IL-10-/- counterparts on day 28 following C. coli infection. Furthermore, C. coli-induced colonic immune cell responses were less pronounced in TLR4-/- IL-10-/- as compared to IL-10-/- mice and accompanied by lower pro-inflammatory mediator concentrations in the intestines and the liver of the former versus the latter. In conclusion, our study provides evidence that TLR4 is involved in mediating C. coli-LOS-induced immune responses in intestinal and extra-intestinal compartments during murine campylobacteriosis.","https://refubium.fu-berlin.de/handle/fub188/29012||http://dx.doi.org/10.17169/refubium-28762","eng","https://creativecommons.org/licenses/by/4.0/","600 Technik, Medizin, angewandte Wissenschaften::610 Medizin und Gesundheit::610 Medizin und Gesundheit","Toll-like receptor-4||lipooligosaccharide||Campylobacter coli||campylobacteriosis model||host-pathogen interaction||secondary abiotic IL-10−/− mice||pro-inflammatory immune responses||intestinal immunopathology||extra-intestinal immune responses","Toll-Like Receptor-4 Is Involved in Mediating Intestinal and Extra-Intestinal Inflammation in Campylobacter coli-Infected Secondary Abiotic IL-10−/− Mice","Wissenschaftlicher Artikel","open access","1882","10.3390/microorganisms8121882","Microorganisms","12","MDPI AG","33261211","8","2076-2607","Charité - Universitätsmedizin Berlin","no"
