Abstract:
HIV-1 neutralizing monoclonal antibodies (MAbs) define key targets for vaccine development and are being considered for passive prevention of infection. We analyzed the interaction of MAbs to two independent epitopes on the viral envelope glycoprotein. Potently neutralizing MAbs to the CD4 binding site and V1V2 region displayed no in vitro cross-competition and displayed additive, though not synergistic, neutralization activity. Predicted neutralization coverage of a combination of two MAbs reached 97% on a 208-isolate panel.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
