Release of cytoprotective PGE2 from cultured macrophages induced by antacids and sucralfate. 1986

I Szelenyi, and R Lanz

Aluminium-containing antacids and sucralfate possess cytoprotective effects supposedly due to the release of endogenous prostaglandins. In the present study possible mechanisms of prostaglandin production by aluminium-containing and related compounds were investigated in cultured macrophages. We found no indication that mechanical action, particle size or hyperosmolality (up to certain limits) play a major role in initiating enhanced prostaglandin production. Instead, it is likely that specific physicochemical properties as surface charge and the corresponding octahedral crystalline structure of Al(OH)3 are major factors mediating the necessary membrane interactions leading to prostaglandin release.

UI MeSH Term Description Entries
D008264 Macrophages The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

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
