Prostaglandins and inflammation: enhancement of monocyte chemotactic responsiveness by prostaglandin E2.
The effects of prostaglandins on human monocyte chemotaxis were studied in vitro. None of the prostaglandins tested, including members of the A, B, E or F series, were chemotactic for monocytes. Prostaglandin E2 however, enhanced the chemotactic responsiveness of monocytes to complement - activated human serum by almost 200%. The enhancement of chemotaxis was not directly related to the ability of PGE2 to raise intracellular cyclic AMP levels. These studies support a role for prostaglandins as modulators of the inflammatory response.
