Evidence from a large body of studies indicates that CD44 is involved in a number of important biological processes, including lymphocyte activation and homing, hematopoiesis, and tumor progression and metastasis. A proper understanding of the role of CD44 in these processes has been severely hampered by a lack of insight into the mode in which CD44 communicates with intracellular signal transduction pathways. In this report, we have addressed this aspect of CD44 functioning by studying CD44 signaling in T lymphocytes. We show that ligation of CD44 by monoclonal antibodies (mAbs) transduces signals to T cells which lead to tyrosine phosphorylation of ZAP-70 and other intracellular proteins. In vitro kinase assays demonstrate that cross-linking of CD44 induces an increase in the intrinsic activity of p56lck. Furthermore, immunoprecipitations show that CD44 is physically associated with p56lck. Our findings suggest that tyrosine kinases, particularly p56lck, play a central role in CD44 mediated signaling.
