BACKGROUND & OBJECTIVES Structural interventions have the capacity to improve the outcomes of HIV/AIDS interventions by changing the social, economic, political or environmental factors that determine risk and vulnerability. Marginalized groups face disproportionate barriers to health, and sex workers are among those at highest risk of HIV in India.(More)
The gB glycoprotein of herpes simplex virus type 1 is involved in viral entry and fusion and contains a predicted membrane-anchoring sequence of 69 hydrophobic amino acids, which can span the membrane three times, near the carboxy terminus. To define the membrane-anchoring sequence and the role of this hydrophobic stretch, we have constructed deletion(More)
Herpes simplex virus (HSV) buds from the inner nuclear membrane of the infected cells. The glycoprotein gB-1 of HSV contains a stretch of 69 hydrophobic amino acids near the COOH terminus and a 109-amino acid cytoplasmic domain. By oligonucleotide-directed mutagenesis, five gB-1 mutants were constructed which either lack a cytoplasmic tail or contained 3,(More)
Enveloped animal viruses enter host cells either by direct fusion at neutral pH or by endocytosis. Herpes simplex virus (HSV) is believed to fuse with the plasma membrane of cells at neutral pH, and the glycoproteins gB and gD have been implicated in virus entry and cell fusion. Using cloned gB or gD genes, we show that cells expressing HSV-1 glycoproteins(More)
