Abstract:
Lentiviruses have a long-documented association with macrophages. Abundant evidence exists for in vitro and, in a tissue-specific manner, in vivo infection of macrophages by the primate lentiviruses HIV-1 and SIV. However, macrophage contribution to aspects of HIV-1 and SIV pathogenesis, and their role in viral persistence in individuals on suppressive antiretroviral therapy, remains unclear. Here we discuss recent evidence implicating macrophages in HIV-1-mediated disease and highlight directions for further investigation.
Insights
Macrophages are key targets for lentiviruses like HIV-1 and SIV. This review explores their role in disease and viral persistence, even during treatment.
Area of Science:
- Immunology
- Virology
- Cell Biology
Background:
- Lentiviruses, including Human Immunodeficiency Virus type 1 (HIV-1) and Simian Immunodeficiency Virus (SIV), are known to infect macrophages.
- Macrophages play a critical role in the immune system and are susceptible to lentiviral infection both in vitro and in vivo.
Purpose of the Study:
- To review current evidence on the involvement of macrophages in lentiviral pathogenesis.
- To explore the role of macrophages in viral persistence, particularly in individuals undergoing antiretroviral therapy.
- To identify key areas for future research regarding macrophage-lentivirus interactions.
Main Methods:
- Literature review of recent studies on HIV-1 and SIV infection of macrophages.
- Analysis of evidence implicating macrophages in disease progression.
- Discussion of the role of macrophages in viral reservoirs and persistence.
Main Results:
- Macrophages are consistently infected by HIV-1 and SIV.
- Evidence suggests macrophages contribute to lentiviral disease pathogenesis.
- The precise role of macrophages in viral persistence during suppressive therapy requires further elucidation.
Conclusions:
- Macrophages are significantly implicated in lentiviral infections and associated diseases.
- Further research is needed to fully understand macrophage contributions to viral persistence and pathogenesis.
- Targeting macrophages may offer new therapeutic strategies for lentiviral infections.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
