Abstract

Introduction: The pathogenesis and immune response to chronic viral infection are multifaceted especially for HIV infection. The effect of HIV on the systemic immune environment of the infected individual is profound and triggered by multiple stimuli. While replication-competent viral infection induces a large spectrum of immune responses, such as cytokine release, we focused on what happens when cells are exposed to replication-incompetent virions and their components.
Results: Monitoring the cytokines released from T cell lines exposed to HIV virion components, we found several cytokines were upregulated with IL-16 being the most upregulated. HIV virion components induced Caspase-3 activation which is required for IL-16 release and this IL-16 release is dependent on protein components within the HIV virion.
Conclusion: Overall, this work allows us to see that replication-incompetent HIV virions have an impact on the immune landscape of a person infected by HIV. We see that exposure of T cells to HIV virion proteins leads to Caspase-3 activation and subsequent IL-16 release.
