[The chemotaxis effect of ampelopsin on the immunocytes].


PMID 16850726

Abstract

To study the chemotaxis effect of ampelopsin with different concentration on monocytes and neutrophilic granulocytes. Chemokinesis and chemotaxis tests were proceed in agarose gel comparing with chemokine IL-8 or MCP-1. At 25.6 microg/ml or 51.2 microg/ml, ampelopsin could strongly enhance the migration of neutrophilic granulocytes and monocytes. The chemotaxis effect induced by 25.6 microg/ml of ampelopsin had no significant differences with that induced by 150 ng/ml of IL-8 or 50 ng/ml of MCP-1 (P > 0.05). At a concentration of 12.8 microg/ml, the chemokime effect of ampelopsin was more potent than that of 150 ng/ml of IL-8 or 100 ng/ml of MCP-1 (P < 0.05). Ampelopsin exerted a synergistic action with IL-8 or MCP-1 on its chemotaxis effect to neutrophilic granulocytes and monocytes. Ampelopsin can strongly enhance the chemokinesis and chemotaxis effects of neutrophilic granulocytes and moncytes and exert a synergistic action with IL-8 or MCP-1 on its chemotaxis effect to neutrophilic granulocytes and monocytes.
