Description

Bélanger and colleagues showed in 2026 that two HIV proteins shield infected cells from being eaten by immune cells. Antibody-dependent cellular phagocytosis, or ADCP, is a process where antibodies flag infected cells for swallowing by scavenger cells. HIV's envelope protein is the only viral target on an infected cell's surface, but it usually stays in a closed shape that antibodies miss.

Deleting Nef and Vpu from HIV copies made infected cells vulnerable to swallowing when HIV-positive plasma was present. Small compounds that mimic CD4 forced the envelope open and likewise sensitised infected cells to ADCP. Boosting surface envelope through an interferon-driven protein raised the effect further. The authors argue ADCP can be harnessed alongside other antibody attacks to shrink the HIV reservoir.
