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 .
 ICAM-I, LFA-3, human T cells, HTLV-I TaxI, ICAM-I, LFA-I, ATL-derived cell lines
