HIV-1 Gag and Amyloid Protein Compete for Key Cellular Resources: Study

Rapid Summary

• Research published in Proceedings of the National Academy of Sciences, Volume 122, Issue 34 (August 2025), highlights a new finding about HIV-1.
• The study explores how HIV-1 interacts with macrophages and microglia as reservoirs, including in the brain, where infection is linked to neurocognitive disorders.
• Findings indicate that HIV-1 promotes the ubiquitination of an amyloidogenic C-terminal fragment.

Indian Opinion Analysis
This research adds a layer to understanding how diseases like HIV impact cognitive health through biological mechanisms involving brain cells such as macrophages and microglia. While it focuses on broader implications for neurocognitive disorders globally, India-home to one of the world’s largest populations affected by HIV-might benefit from deeper investigation into localized factors connected to this pathway. Advancing biomedical research specific to India’s healthcare needs could pave the way for improved care and treatment protocols concerning both cognitive complications arising from infections such as HIV and broader public health strategies addressing neurological disorders.Read More
