Understanding how mutations in a virus affect its behavior in animal models

Official title: Determining the Functional Significance of Mutations Observed in Envelope Protein Following Serial In Vivo Passaging of Human-Simian Immunodeficiency Virus

Funded at Texas Biomedical Research Institute · NIH-10897301 · Data updated 2026-11-12

This study is looking at how changes in a specific virus protein affect how well the Human-Simian Immunodeficiency Virus (HSIV) can infect and grow in pigtail macaques, which helps researchers learn more about HIV and could lead to better treatments and vaccines for people living with HIV/AIDS.

Who could benefit from this research

Could help

Ideal candidates for benefiting from this research include individuals living with HIV/AIDS or those at high risk of infection who may benefit from advancements in treatment and prevention strategies.

Less likely to help

Patients who are not infected with HIV or those who do not have a risk of exposure to the virus may not receive direct benefits from this research.

What this research studies

This research investigates how mutations in the envelope protein of the Human-Simian Immunodeficiency Virus (HSIV) influence its ability to infect and replicate in animal models, specifically pigtail macaques. By performing serial in vivo passaging, the study aims to enhance the virus's infectivity and replicative capacity, which could provide insights into HIV pathogenesis and the development of effective vaccines. The research utilizes advanced animal models to mimic human HIV infection more closely, potentially leading to better understanding and treatment strategies for AIDS. Patients may benefit indirectly from this research as it could lead to breakthroughs in HIV treatment and prevention.

Why it matters

Potential benefit: If successful, this research could lead to improved understanding of HIV infection and the development of more effective vaccines and treatments for AIDS.

How similar studies have gone: Previous research using similar animal models has shown promise in understanding HIV pathogenesis and developing effective treatments, indicating that this approach has potential for success.
