In this study, we show that HLA class I -mediated induction of cell proliferation correlates with inactivation of the Rb protein in the T cell line Jurkat as well as human aortic endothelial cells .
 ( protein: Rb protein, None) , ( protein: HLA class I, None) , ( cell line: T cell line Jurkat, None) , ( cell type: human aortic endothelial cells, None)
