IL6 and infection: Lipopolysaccharide and ATP treatment of intestinal epithelial cells and infection with T. gondii in vitro did not promote inflammasome-associated interleukin-1β (IL-1β) or IL-18 secretion, but promoted C–C motif chemokine ligand 5 (CCL5), tumour necrosis factor-α and IL-6 production that were significantly reduced when the P2X7R was blocked.
