pubmed-article:7988553 | pubmed:abstractText | The role played by the cytoplasmic domain of the CD4 molecule in the process of HIV infection was investigated, using A2.01 cells which express different forms of the CD4 gene. A delay in HIV production was consistently observed in cells expressing a truncated CD4 which lacks the cytoplasmic domain (CD4.401) compared with cells expressing the wild type CD4. The delay was much less in cells expressing a hybrid CD4-CD8 molecule (amino acids 1-177 of CD4 fused to the hinge, transmembrane and cytoplasmic domains of CD8). Yet the extent of viral entry and reverse transcription, monitored by semi-quantitative PCR, was similar in each cell type studied. For further study of the mechanism responsible for delayed HIV replication in the A2.01/CD4.401 cell line, cells were treated with phytohaemagglutinin (PHA), 24 h after HIV infection. Under such experimental conditions HIV production was detected at the same time in the culture supernatants of A2.01/CD4 and A2.01/CD4.401 cells. Moreover, we found that CD4 oligomerization by HIV-1 induced NF-kappa B translocation in A2.01/CD4 and A2.01/CD4-CD8 but not in A2.01/CD4.401 cells. This was consistent with CAT assay experiments which provided evidence for Tat-independent NF-kappa B mediated activation of HIV-1 LTR promoter after HIV binding to CD4 in A2.01/CD4 and A2.01/CD4-CD8 but not in A2.01/CD4.401 cells. In contrast to results published recently by Tremblay et al. (1994, EMBO J., 13, 774-783), we propose that a positive cellular signal initiated following oligomerization of the CD4 by the virus itself is involved in NF-kappa B-dependent early HIV transcription in A2.01/CD4 cells. | lld:pubmed |
