Pseudotyped HIV-1 infects primary vaginal squamous epithelial cells.

<p>(<b>A, B</b>) Dual immunofluorescence staining with FITC-anti-HIV-1 Gag and anti-CK19 MAbs was performed on primary vaginal squamous epithelial cells which were exposed to progeny virus from infected CEMX174 cells. HIV-1 Gag is shown as green and CK19 is shown as red. Corresponding bright field images are also shown as indicated. The input viruses used to infect producer CEMX174 cells is indicated on the panels. Epithelial cells exposed to progeny virus in the presence of AZT or anti-MLV polyclonal sera diluted 1∶300 are shown in the left two columns in <b>B</b>.
