The membrane-proximal external region (MPER) of the HIV-1 gp41 consists of epitopes for the broadly cross-neutralizing monoclonal antibodies 2F5 and 4E10. However, antigens containing the linear sequence of these epitopes are unable to elicit potent and broad neutralizing antibody responses

Although significant variations in the metabolic profiles exist among different cells, little is understood in terms of genetic regulations of such cell type-specific metabolic phenotypes and nutrient requirements. While many cancer cells depend on exogenous glutamine for survival to justify

The initial events of HIV-1 cell infection involve the sequential binding of the viral envelope glycoprotein gp120 to the cellular CD4 receptor and the coreceptor, usually CCR5 or CXCR4. Binding to the coreceptor triggers the chain of events that culminates

Human BChE (butyrylcholinesterase) protects against the toxicity of organophosphorus nerve agents and pesticides. BChE purified from human plasma is limited and pathogen carry-over is a concern. Unlike the native BChE tetrameric complex with a residence time of days, rBChE (recombinant

In the HIV vaccine field, there is a need to produce highly immunogenic forms of the Env protein with the capacity to trigger broad B and T-cell responses. Here, we report the generation and characterization of a chimeric HIV-1 gp120
