Lipopolysaccharide and silica-stimulated mononuclear cell prostaglandin production in ulcerative colitis

Basal, lipopolysaccharide (LPS) and silica-stimulated prostaglandin (PG) production were compared between peripheral blood mononuclear cells (PBMNC) from UC patients and healthy subjects (HS). Basal and LPS-stimulated PBMNC PGI2, but not PGE2, production was greater in UC. LPS stimulated both PGE2 a...

description Basal, lipopolysaccharide (LPS) and silica-stimulated prostaglandin (PG) production were compared between peripheral blood mononuclear cells (PBMNC) from UC patients and healthy subjects (HS). Basal and LPS-stimulated PBMNC PGI2, but not PGE2, production was greater in UC. LPS stimulated both PGE2 and PGI2 by PBMNC from HS and UC patients. Silica stimulated production of both PGs by cells from HS but only PGE2 by cells from UC patients. The differences in responses to silica and LPS may result from differences in activation of NFκB or, alternatively, prior sensitisation to one of these agents. That PBMNC PGE2 production is not increased in UC, as it is in Crohn’s disease, suggests that there are differences in PBMNC behaviour between these two diseases.
