From: The inhibition of assembly of HIV-1 virus-like particles by 3-O-(3',3'-dimethylsuccinyl) betulinic acid (DSB) is counteracted by Vif and requires its Zinc-binding domain

DSB treatment of Sf9 cells coexpressing Pr55Gag and Vifwt. Sf9 coinfected with AcMNPV-Pr55Gag and AcMNPV-Vifwtat equal MOI of each (5 PFU/cell) were treated with DSB at 10 μg/ml for 30 h at 18 h pi. Cells were harvested at 48 h pi, and processed for EM. (a), General view of a cell. (b), Enlargement of a submembranal region of the cell showing VLP in the process of exocytosis. Note the abundance of VLP in the vesicular compartment in panels (a) and (b). VLP-containing vesicles reminiscent of MVBs observed in mammalian cells are indicated with arrows.
