The National Institutes of Health (NIH) has announced a funding opportunity titled "Targeting Inflammasomes in HIV and Substance Use (R21 Clinical Trial Not Allowed)" aimed at supporting research on the role of inflammasomes in the context of HIV infection and substance use disorders (SUD). This initiative seeks to explore the mechanisms of inflammasome activation and its impacts on neurocognitive disorders and immune function among individuals affected by HIV and SUD, with a focus on identifying molecular markers and assessing the cellular environments influencing inflammasome activity. The total funding pool for this opportunity is $2,000,000, which will support up to four awards over a two-year period, with proposals due by February 13, 2024. Interested applicants can find more information and application guidelines at the NIH grants website or contact NIH Grants Information at grantsinfo@nih.gov.
