National Institutes of Health

Who can apply

Other Eligible Applicants include the following: Alaska Native and Native Hawaiian Serving Institutions; Asian American Native American Pacific Islander Serving Institutions (AANAPISISs); Eligible Agencies of the Federal Government; Faith-based or Community-based Organizations; Hispanic-serving Institutions; Historically Black Colleges and Universities (HBCUs); Indian/Native American Tribal Governments (Other than Federally Recognized); Non-domestic (non-U.S.) Entities (Foreign Organizations); Regional Organizations; Tribally Controlled Colleges and Universities (TCCUs) ; U.S. Territory or Possession.

About this opportunity

The purpose of this notice of funding opportunity (NOFO) is to support research to elucidate how HIV-induced immunometabolic alterations, in a host suppressed on combination antiretroviral therapy (cART-suppressed), impact the immune response and increase risk for poor outcomes due to a second, potentially long-term, infection such as Mycobacterium tuberculosis (Mtb) or Hepatitis B Virus (HBV). This NOFO aims to support research to define how HIV-driven alterations to immunometabolism affect immune cell regulation, cell-cell interactions, response to treatment, and, ultimately, Tuberculosis (TB) and HBV disease progression.
