Developing effective vaccines and treatments for HIV-1 infection remains a challenge due to drug resistance and the lack of a safe vaccine. Advanced animal models are crucial for guiding the development of new HIV/AIDS therapies and prevention strategies.

Area of Science:

Virology
Immunology
Public Health

Background:

The Acquired Immunodeficiency Syndrome (AIDS) pandemic presents ongoing scientific and public health challenges.
Effective antiretroviral therapy (ART) has been a triumph, but drug resistance necessitates continuous treatment management and new drug development.
Despite extensive research, a safe and effective vaccine against Human Immunodeficiency Virus type 1 (HIV-1) remains elusive.

Purpose of the Study:

To highlight the critical role of animal models in advancing HIV/AIDS research.
To emphasize the importance of understanding the strengths and weaknesses of various animal models for preclinical studies.
To guide the design of animal studies for developing novel HIV-1 vaccines and antiretroviral therapies.

Main Methods:

Review of advances in humanized mouse models, non-human primate immunogenetics, and recombinant challenge viruses.

Assessment of the advantages and limitations of current animal models for HIV/AIDS research.

Discussion of how these models facilitate invasive disease investigation and preclinical drug/vaccine testing.

Main Results:

Significant advancements have increased the number and sophistication of available mouse and simian models for HIV/AIDS research.
Animal models provide essential platforms for studying disease progression and evaluating potential interventions.
These models are instrumental in preclinical testing of antiretroviral drugs and vaccine candidates.

Conclusions:

Understanding the specific advantages and limitations of each animal model is essential for effective study design.
Sophisticated animal models are indispensable tools for guiding the development of future HIV-1 vaccines and antiretroviral therapies.
Continued refinement and application of animal models will accelerate progress in combating the HIV/AIDS pandemic.
