Maintenance of an intact human immunodeficiency virus type 1 vpr gene following mother-to-infant transmission.

abstract：:The multifunctional simian and human immunodeficiency virus (SIV and HIV) Nef proteins are important for virulence. We studied the importance of selected Nef functions using an SIV Nef with mutations in two regions that are required for CD4 downregulation. This Nef mutant is defective for downregulating CD4 and, in ad...
