WebNov 19, 2024 · The disease is caused by a few serogroups, and the main factor behind the symptoms is the cholera toxin (CT) encoded by genes located on a prophage mobile genetic element (CTX-φ) that induce severe disruption of intestinal cell function, leading to watery, secretory diarrhea ( 2 ). WebDelta toxin is also a chemoattractant for leukocytes, leading to a surge of cytokines such as interleukin-8 from neutrophils at an infection site. Delta toxin molecules activate a G-protein-coupled receptor expressed in leukocytes called formyl-peptide receptor 2 ( FPR2 ), which binds metabolites to inhibit and lower inflammation. fluke backpack tool bag
