Effect of hirudin on the chemotactic properties of alpha-thrombin.
A study by an agarose technique of the chemotactic power of human alpha-thrombin on polymorphonuclear leukocytes reveals that this enzyme has a chemotactic activity. Hirudin, which inhibits the coagulant properties of thrombin, suppresses these chemotactic properties. This effect could be explained by the binding of hirudin to the structural domain of alpha-thrombin involved in its chemotactic activity.
