More recently, it has become clear that MHC class I molecules can also initiate intracellular signals in endothelial and smooth muscle cells, which synergize with growth factor receptors to elicit cell proliferation. This review describes our current knowledge of class I–mediated signaling pathways in human endothelial and smooth muscle cells. The role of the class I signaling pathway in modulating cell growth and the clinical significance of this pathway in chronic allograft rejection are discussed. %8 2003-04-01
