| pubmed-article:15748898 | pubmed:abstractText | Adipose tissue of HIV-1-infected patients shows severe abnormalities such as profound changes in adipose tissue morphology and metabolism. Does HIV-1 infect the adipose cell remains an unsolved question since previous attempts showed that HIV-1 poorly infects human adipocytes in vitro. In the present study, preadipose cells from human subcutaneous fat pads were differentiated in vitro, checked for HIV receptor expression, then infected with R5 and X4 HIV1 strains. Using a sensitive RT-PCR assay, we showed that HIV-1 tat and rev early viral transcripts were expressed in infected adipocytes giving a clear evidence of HIV-1 transcriptional activity in these cells. However, at the same time, no sign of productive infection was demonstrated since infected adipocytes did not efficiently produce Gag p24 antigen. We hypothesized that such a limitation could result from the lack of activation of adipocyte-signaling pathways able to stimulate HIV-1 gene expression in quiescent adipocytes. Indeed, a significant increase in Gag p24 production was observed after stimulation of infected adipocytes with pro-inflammatory cytokines, such as tumor necrosis factor alpha or interleukin-1-beta. Taken together, these results demonstrate that HIV-1 does infect human adipose cells in vitro and suggest that the initial limited infection can be overcome upon pro-inflammatory cytokine treatment. | lld:pubmed |
