dc.description.abstractCD44 is a principal cell surface receptor for hyaluronan, a major component of extracellular matrices. Cells are surrounded by and encounter matrix in vivo, which in turn serves a variety of cell functions through the direct adhesion via their receptors. CD44 communicates cell-matrix interactions into the cell via “outside-in signaling” and has an important role in biological activities. The interaction of CD44 with fragmented hyaluronan on rheumatoid synovial cells induces expression of VCAM-1 and Fas on the cells, which leads to Fas-mediated apoptosis of synovial cells by the interaction of T cells bearing FasL. On the other hand, engagement of CD44 on tumor cells derived from lung cancer reduces Fas expression and Fas-mediated apoptosis, resulting in less susceptibility of the cells to CTL-mediated cytotoxicity through Fas-FasL pathway. Thus, although the CD44-mediated signaling differs among cells and circumstances, we here propose the functional role of CD44 in inflammatory processes and tumor susceptibility and the rational design of future therapeutic strategies including the exploitation of CD44-mediated pathway in vivo.es
