SMARCB1 and HIV-1 infection: To examine the influence of either cellular INI1 present in the target cells or the virally incorporated INI1 during HIV-1 infection, we tested the efficacy of infecting INI1-defective rhabdoid cells, MON and STA-WT1, by the VSVG pseudotyped virions produced in 293T cells, using GFP as the marker.
