Abstract excerpt
In the absence of viral envelope gene expression, cells expressing human immunodeficiency virus type 1 (HIV-1) gag and pol, accessory HIV functions, and a vector genome RNA produce and secrete large amount of noninfectious virus-like particles (VLPs) into the conditioned medium. After partial purification, such HIV-1 VLPs can be made infectious in cell-free conditions in vitro by complex formation with...
