Structure of a cleavage-independent HIV Env recapitulates the glycoprotein architecture of the native cleaved trimer

Abstract

Native-like soluble HIV envelope (Env) trimers are potential vaccine immunogens, and elimination of furin-dependence could provide a DNA-based alternative. Here, Sarkar et al. show that a cleavage-independent Env construct recapitulates the architecture and glycosylation of the native cleaved trimer.
