The National Institutes of Health (NIH) has announced a funding opportunity for the "Multidisciplinary Studies of HIV/AIDS and Aging" through the R21 Exploratory/Developmental Research Grant program. This initiative aims to support research that enhances the understanding of the biological, clinical, and socio-behavioral aspects of aging in individuals living with HIV, as well as to improve strategies for testing, prevention, and treatment of HIV-related comorbidities. The program is particularly relevant given the increasing number of older adults with HIV, emphasizing the need for interdisciplinary approaches to address these complex health challenges. Interested applicants can apply for a maximum budget of $275,000 over two years, with applications due by April 4, 2024.
