The HIV-1 envelope glycoprotein complex (Env) is a trimeric, heavily glycosylated class I viral fusion protein that protrudes from the viral membrane and serves as the sole mediator of viral entry into host cells9. Each Env protomer consists of a surface gp120 glycoprotein non-covalently associated with a transmembrane gp41 glycoprotein, together forming a metastable trimer that is primed to undergo receptor-induced conformational rearrangements during viral entry10. High-resolution structural studies have shown that gp120 comprises a conserved inner domain, a heavily glycosylated outer domain, variable loops (V1–V5), and a bridging sheet that forms a critical component of the co-receptor binding interface following receptor engagement11. In contrast, gp41 contains the N-terminal fusion peptide, heptad repeat regions (HR1 and HR2), membrane-proximal external region (MPER), transmembrane domain, and cytoplasmic tail (CT). These domains collectively mediate membrane fusion, with the fusion peptide and HR1/HR2 driving six-helix bundle formation, the MPER contributing to membrane destabilization and serving as a conserved target for broadly neutralizing antibodies, and the CT coordinating Env incorporation during virion assembly10. The extensive N-linked glycosylation of gp120 forms a dense glycan shield that masks conserved protein epitopes from antibody recognition. Each HIV-1 Env trimer carries approximately 90 N-linked glycans (≈30 per gp120 protomer),...
