Furthermore, transporters involved in absorption of Na+ and Cl−, such as the ENaC (epithelial sodium channel), NHE3 (sodium-hydrogen antiporter 3) or DRA (down-regulated in adenoma), became the focus of our attention since they can be influenced by pro-inflammatory cytokines, as also shown in campylobacteriosis [5]. Here, SLC9A3 is linked to campylobacteriosis.
