The present study was undertaken to determine the role of HTLV-I TaxI in the up-regulation of ICAM-I and LFA-3 in human T cells transformed with HTLV-I and the mechanism of down-regulation of ICAM-I and LFA-I in ATL-derived cell lines .
 ( protein: ICAM-I, None) , ( protein: LFA-3, None) , ( cell type: human T cells, None) , ( protein: HTLV-I TaxI, None) , ( protein: ICAM-I, None) , ( protein: LFA-I, None) , ( cell line: ATL-derived cell lines, None)
