Summary
Modeling human immunodeficiency virus type 1 (HIV-1) latency is challenging. Humanized mouse models offer a promising approach to study HIV-1 infection and immune responses, advancing anti-retroviral therapy development.
Area of Science:
- Immunology
- Virology
- Infectious Diseases
Background:
- Long-lasting cellular reservoirs of human immunodeficiency virus type 1 (HIV-1) present a major obstacle to effective anti-retroviral therapies.
- Latent HIV-1 infection involves dormant cells evading immune responses, complicating in vitro and in vivo modeling.
Purpose of the Study:
- To review the complexities of modeling HIV-1 latency in vitro and in vivo.
- To highlight recent advancements in humanized mouse models for studying HIV-1 infection.
Main Methods:
- Utilizing humanized mouse models with engrafted human cells and tissues.
- Modeling human innate and adaptive immune responses in immunocompromised murine scaffolds.
- Investigating HIV-1 transmission, pathogenesis, immune responses, and treatment efficacy.
Main Results:
- Humanized mice successfully mimic key aspects of HIV-1 infection, including transmission and pathogenesis.
- These models enable the study of complex host immune responses to HIV-1.
- Recent advancements provide improved systems for studying viral latency.
Conclusions:
- Humanized mouse models are valuable tools for understanding HIV-1 latency and developing novel therapeutic strategies.
- These models bridge the gap between in vitro studies and in vivo human infections.
- Further development of these models will accelerate progress in combating HIV-1 reservoirs.
