Toxins A and B bind to, and are endocytosed by, intestinal epithelial cells. It is thought that only the enzyme domain enters the cytosol from acidic endosomal compartments. In the cytosol, the toxins glucosylate Rho GTPases, which inhibits Rho protein functions and Rho signalling pathways. The tight junctions, and therefore the barrier function, of the epithelium are disturbed, which results in diarrhoea. Epithelial cells produce inflammatory factors, including interleukin-8 (IL8) and macrophage inflammatory protein 2 (MIP2). Toxins that reach subepithelially located monocytes and macrophages might stimulate release of cytokines. Similarly, toxins A and B induce activation of intestinal neuronal cells to release corticotropin-releasing hormone (CRH) and substance P, which also activates macrophages and monocytes. Neutrophil invasion occurs, which induces a dramatic inflammatory response.
