Abstract
A number of molecules were found to alter the motility of tunicate hem ocytes. Bacterial lipopolysaccharide (LPS) significantly enhanced cell mobility relative to non-stimulated controls. Responses to LPS mere n ot directional and so represented chemokinesis. In contrast, checkerbo ard analyses indicated that two tunicate hemolymph proteins, tunIL1-al pha and -beta, stimulated truly directional chemotaxis by hemocytes. T he data suggest that tunIL1 proteins may contribute to defense by alte ring the localization of immunocompetent cells. (C) 1998 Academic Pres s.
