Formyl peptide receptor 1 signalling promotes experimental colitis in mice

Inflammatory bowel disease is characterised by intricate immune cell interactions with tissue cells and such cross-talks can become deregulated. The formyl peptide receptor 1 (Fpr1) is expressed by both immune and stromal cells including epithelial cells. We evaluated the development of the physiopathology of the DNBS induced colitis in Fpr1 KO mice on the C57BL/6 genetic background compared to C57BL/6 genetic background animals. We have...
