Prostanoid synthesis by cultured intestinal epithelial and mononuclear cells in inflammatory bowel disease. 1983

A Zifroni, and A J Treves, and D B Sachar, and D Rachmilewitz

Intestinal epithelial and mononuclear cells were isolated from normal colonic mucosa and from intestinal mucosa of inflammatory bowel disease patients. Prostanoid synthesis by primary cultures of intestinal mononuclear cells were four to six fold higher than its synthesis by primary cultures of epithelial cells. Prostaglandin E2, prostacyclin and thromboxane A2 synthesis by cultured mononuclear cells isolated from inflamed ileal mucosa of four Crohn's disease patients: 5.6 +/- 1.2; 3.2 +/- 1.9 and 2.4 +/- 1.4 (mean +/- SE) ng/1 X 10(6) cells were significantly higher than their respective synthesis by cultured mononuclear cells isolated from uninflamed ileal mucosa isolated from the same patients: 0.8 +/- 0.1; 0.3 +/- 0.1 and 0.2 +/- 0.03 ng/1 X 10(6) cells or from normal colonic mucosa: 1.5 +/- 0.3; 0.3 +/- 0.1 and 0.5 +/- 0.1 (N = 12) ng/1 X 10(6) cells. Prostanoid synthesis by primary cultures of intestinal mononuclear cells isolated from colonic mucosa of five ulcerative colitis patients was enhanced but not significantly different from its synthesis by cells isolated from normal subjects. These results suggest that the enhanced intestinal prostanoid synthesis in active Crohn's disease is derived from stimulated local mononuclear cells and may have an important role in the pathogenesis of the disease.

UI	MeSH Term	Description	Entries
D007413	Intestinal Mucosa	Lining of the INTESTINES, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. In the SMALL INTESTINE, the mucosa is characterized by a series of folds and abundance of absorptive cells (ENTEROCYTES) with MICROVILLI.

D011453	Prostaglandins	A group of compounds derived from unsaturated 20-carbon fatty acids, primarily arachidonic acid, via the cyclooxygenase pathway. They are extremely potent mediators of a diverse group of physiological processes.	Prostaglandin,Prostanoid,Prostanoids
D011458	Prostaglandins E	(11 alpha,13E,15S)-11,15-Dihydroxy-9-oxoprost-13-en-1-oic acid (PGE(1)); (5Z,11 alpha,13E,15S)-11,15-dihydroxy-9-oxoprosta-5,13-dien-1-oic acid (PGE(2)); and (5Z,11 alpha,13E,15S,17Z)-11,15-dihydroxy-9-oxoprosta-5,13,17-trien-1-oic acid (PGE(3)). Three of the six naturally occurring prostaglandins. They are considered primary in that no one is derived from another in living organisms. Originally isolated from sheep seminal fluid and vesicles, they are found in many organs and tissues and play a major role in mediating various physiological activities.	PGE
D011464	Epoprostenol	A prostaglandin that is a powerful vasodilator and inhibits platelet aggregation. It is biosynthesized enzymatically from PROSTAGLANDIN ENDOPEROXIDES in human vascular tissue. The sodium salt has been also used to treat primary pulmonary hypertension (HYPERTENSION, PULMONARY).

D003424	Crohn Disease	A chronic transmural inflammation that may involve any part of the DIGESTIVE TRACT from MOUTH to ANUS, mostly found in the ILEUM, the CECUM, and the COLON. In Crohn disease, the inflammation, extending through the intestinal wall from the MUCOSA to the serosa, is characteristically asymmetric and segmental.
