Abstract

Human immunodeficiency virus (HIV) continues to be a global health challenge, with over 38 million people infected by the end of 2022. HIV-1, the predominant strain, primarily targets and depletes CD4+ T cells, leading to immunodeficiency and subsequent vulnerability to opportunistic infections. Despite the progress made in antiretroviral therapy (ART), drug resistance and treatment-related toxicity necessitate novel therapeutic strategies. This review delves into the intricate interplay between HIV-1 and host cellular proteins throughout the viral life cycle, highlighting key host factors that facilitate viral entry, replication, integration, and immune evasion. A focus is placed on actual findings regarding the preintegration complex, nuclear import, and the role of cellular cofactors such as FEZ1, BICD2, and NPC components in viral transport and genome integration. Additionally, the mechanisms of immune evasion via HIV-1 proteins Nef and Vpu, and their interaction with host MHC molecules and interferon signaling pathways, are explored. By examining these host-virus interactions, this review underscores the importance of host-targeted therapies in complementing ART, with a particular emphasis on the potential of genetic research and host protein stability in developing innovative treatments for HIV/AIDS.
