Downregulation of HLA Class I Antigensin HIV-1-Infected Cells

- By means of indirect immunofluorescence analysis we investigated the effect of HIV -1 infection on HLA class I surface antigens. We report here that in CD4\(^+\) HeLa cells, in H9 cells, and in peripheral T Iymphocytes HLA class I antigens are down regulated following infection with HIV -1. The downregulation is effected at a posttranscriptional level since the amounts of HLA class I specific mRNA are similar in infected and uninfected cells. This phenomenon is not only correlated with the state of infection, that is, the presence of P24 ofBy means of indirect immunofluorescence analysis we investigated the effect of HIV -1 infection on HLA class I surface antigens.

The downregulation is effected at a posttranscriptional level since the amounts of HLA class I specific mRNA are similar in infected and uninfected cells. This phenomenon is not only correlated with the state of infection, that is, the presence of P24 of HIV-l in the cells, but also depends on the time of infection. Upon HLA class I downregulation by HIV infection, the specific lysis of peripheral blood cells by allogeneic CTL is reduced.…
