Abstract/OtherAbstract:
Glycolipid compositions of cells infected by human retroviruses (human immunodeficiency virus, HIV and/or human T-cell lymphotropic virus type I, HTLV-I) have been studied. Eight cell lines, comprising two HTLV-I-infected T-cell lines (MT-2 and MT-4), two HTLV-I-negative T-cell lines (Jurkat and MF), a macrophage cell line (U937), and three HIV-infected counterpart cell lines (MT-4/HIV, Jurkat/HIV and U937/HIV) were used. The neutral glycolipids and gangliosides isolated from these cell lines were compared. Among them, the HTLV-I-infected T-cell lines, MT-2 and MT-4, showed similar patterns for both neutral glycolipids and gangliosides. Neutral glycolipids (GlcCer and LacCer) of MT-2 and MT-4 cells were markedly decreased, and a ganglioside, GM3, of theirs was decreased to only a trace amount compared to that in other cell lines. Gangliosides of MT-4 and MT-4/HIV were further separated on an Iatrobeads column, and were identified as GM2, GM1a and GD1a by methylation and liquid secondary ion mass spectrometric analyses. Since the patterns of neutral glycolipids and gangliosides of MT-2 and MT-4 are unique, as compared to those of HTLV-I-negative cells, it is suggested that these changes are related to HTLV-1 infection. No prominent differences in the ganglioside compositions between HIV-infected and non-infected cell lines could be observed. But it is noteworthy that the contents of asialo-GM2 in Jurkat/HIV and MT-4/HIV cells were increased as compared to those in the parental cell lines.
