Project description:The Clostridioides difficile toxins TcdA and TcdB are responsible for diarrhea and colitis. The aim of this project was to explore the effects of the toxins on epithelial barrier function and the molecular mechanisms for diarrhea and inflammation. RNA-seq of toxin-treated intestinal cell monolayers was performed to describe the C. difficile-mediated effects. mRNA profiles from intestinale epithelial cells were generated by deep sequencing using Illumina NovaSeq 6000. This data provide the basis for subsequent upstream regulator analysis.
Project description:The anaerobic, spore-forming pathogen Clostridioides difficile infects the gastrointestinal tract of higher mammals, including humans, and is the major causative agent of antibiotic-associated diarrhea. Moreover, recurrence and re-infection rates after a first successful antibiotic therapy are substantially high. To overcome the problem of recurrence and re-infection new antibiotics are urgently required that are more selective for the pathogen but spare other members of the microbiota. In turn, the microbial community inside the intestine is allowed to recover and to re-establish colonization resistance to protect against recurrence. The data presented here aim at analyzing the ability of the macrolide compound chlorotonil A to meet the requirements of C. difficile specific drug.
