While the role of T lymphocytes has been extensively explored, recent research has illuminated the critical involvement of B lymphocytes and their dysfunction in the context of HIV/AIDS. This review delves into the implications of B lymphocyte dysfunction, dissecting its impact on humoral immunity, immunopathogenesis, vaccine development, and potential therapeutic interventions. In the realm of therapeutic interventions, this review evaluates current and potential strategies to rectify B lymphocyte dysfunction, ranging from immune modulatory therapies to targeted treatments aimed at restoring humoral immunity. The narrative concludes by outlining future perspectives, emphasizing the identification of biomarkers, advancements in vaccine design, and interdisciplinary collaboration as key areas of focus for further research. Keywords: B lymphocytes, HIV/AIDS, humoral immunity, immunopathogenesis, vaccine development, therapeutic interventions. Introduction Human Immunodeficiency Virus (HIV) remains a global health challenge, affecting millions of individuals worldwide and demanding continuous scientific scrutiny. Over the decades, research has predominantly focused on the role of T lymphocytes in the immunopathogenesis of HIV/AIDS, revealing intricate details about the cellular arm of the immune response. However, recent scientific endeavors have shifted the spotlight to B lymphocytes, emphasizing their underexplored yet pivotal role in the dynamic host-virus interplay. 1-5 The immune system's
