摘要：
Embodiments of the present disclosure encompasses virus-like particles, methods of making virus-like particles, including expression vectors, wherein the virus-like particles may comprise enhanced levels of capsid-bound a chimeric HN-Env polypeptide compared to VLPs derived from unmodified HIV-env polypeptides. Embodiments of the virus-like particle may have Env-specific epitopes exposed on the outer surface thereof. In one embodiment, the Env-specific epitopes exposed on the outer surface of the virus-like particle may specifically bind with an anti-HIV-Env specific antibody. Embodiments of the disclosure further includes methods of generating an antibody specific to an epitope of an HIV-Env polypeptide, comprising delivering to an animal or a human an effective amount of a suspension of virus-like particles comprising a chimeric HIV-Eny polypeptide, thereby inducing the formation of an antibody specific to an epitope of an HIV-1 eny polypeptide.
