Nonhuman primate models are essential for understanding human immunodeficiency virus (HIV) transmission. Recent advancements allow for low-dose infections, accurately mimicking natural HIV infection and aiding vaccine development.

Area of Science:

Virology
Immunology
Primate Models

Background:

Studying early human immunodeficiency virus (HIV) transmission and systemic dissemination is challenging due to ethical and practical limitations in human subjects.
Accurate animal models are crucial for comprehending the initial stages of HIV infection and developing effective interventions.

Purpose of the Study:

This review emphasizes the critical role of nonhuman primate (NHP) models in studying HIV transmission.
It highlights the necessity of NHP models for understanding the early phases of HIV infection.

Main Methods:

Recent discoveries indicate that HIV infection initiates from a small number of transmitted/founder variants.
This finding has led to the development of animal models that replicate physiologically relevant, low-titre infections.

Main Results:

Established NHP models accurately simulate rectal, vaginal, and penile HIV transmission routes.
Models for intravenous and oral HIV transmission are currently under development.

Conclusions:

These refined, limited-dose NHP models offer a realistic experimental platform for evaluating vaccine candidates and other prevention strategies.
Data from NHP and human studies are vital for developing effective future HIV prevention modalities.
