摘要：

A number of molecules were found to alter the motility of tunicate hemocytes. Bacterial lipopolysaccharide (LPS) significantly enhanced cell mobility relative to non-stimulated controls. Responses to LPS mere not directional and so represented chemokinesis. In contrast, checkerboard analyses indicated that two tunicate hemolymph proteins, tunIL1-alpha and -beta, stimulated truly directional chemotaxis by hemocytes. The data suggest that tunIL1 proteins may contribute to defense by altering the localization of immunocompetent cells. (C) 1998 Academic Press.
