Regulation of Virus Release by the Macrophage-Tropic Human Immunodeficiency Virus Type 1 AD8 Isolate Is Redundant and Can Be Controlled by either Vpu or Env

Abstract excerpt

The human immunodeficiency virus type 1 (HIV-1) Vpu and Env proteins are expressed from a bicistronic mRNA. To address the biological significance of the coordinated expression of vpu and env, we compared the relative effects on particle release of HIV-1 isolates containing an intact vpu gene or carrying point mutations in its initiation codon or internal deletions, respectively. We found that the primary AD8...
