Abstract

Two main challenges have impeded the development of an effective HIV-1 envelope (Env) vaccine, with antibodies eliciting neutralisation of virions as well as Fc-effector functions, such as antibody-dependent cytotoxicity (ADCC), phagocytosis (ADP) or complement deposition (ADCD). On one hand, designing the right Env vaccine to elicit humoral or cellular protection has been challenging and, to date, SOSIP-Env trimers which are covalently constrained in the closed, pre-fusion conformation are the best vaccine candidate over uncleaved (Unc), open-structured trimers. On the other hand, eliciting heterologous neutralising antibodies in several animal models (including humans) has been difficult. ..
