Conformation-Dependent Interactions Between HIV-1 Envelope Glycoproteins and Broadly Neutralizing Antibodies.

abstract：:Elite controllers or suppressors (ES) are HIV-1-infected patients who maintain viral loads of <50 copies/ml without antiretroviral therapy. While HLA-B*57 and B*5801 alleles are overrepresented in ES, many HLA-B*57/B*5801 patients become chronic progressors (CP). We show here that HIV-1 infection results in similar le...
