HIV researchers, you may be interested in the new funding opportunity announcement (FOA) Enhancing HIV Reservoir Susceptibility to Elimination (R01, Clinical Trial Not Allowed), whose objectives are to:
- Elucidate cellular and molecular mechanisms within persistently infected HIV reservoir cells that promote survival or resistance to cell killing.
- Identify novel therapeutic targets within persistently infected cells that will increase their sensitivity to virus- or immune-mediated cell death.
- Explore synergistic approaches to combine enhancement of susceptibility to cell death with other eradication strategies. These studies will inform efforts to develop more effective interventions for an HIV cure.
Specific Areas of Research Interest
Applications are expected to define intracellular mechanisms that determine resistance or sensitivity of HIV reservoir cells to cytolytic stimuli. For example, studies may examine programmed cell death pathways, epigenetic regulation, or other host or viral factors that contribute to HIV reservoir survival, longevity, expansion, and responses to virus production or immune targeting.
Studies also may seek to define cellular factors that impact or counteract virus-induced downregulation of major histocompatibility complex (MHC) or impairment of HIV antigen presentation. Understanding how these mechanisms may differ over the course of infection and/or in different cell types or tissue compartments is also of interest.
Studies using primary cells or cell models from humans or relevant animal models must be included. Testing of therapeutic strategies or use of preclinical animal models is not required but may be included as needed to test mechanistic hypotheses.
Areas of Interest for Co-Funding
The National Institute of Mental Health (NIMH) and the National Institute on Drug Abuse (NIDA) will consider co-funding applications that include a focus on the following:
- NIMH—Mechanisms of survival and cell death in persistent reservoirs within the central nervous system, including microglia, macrophages, and astrocytes.
- NIDA—The influence of addictive substances or relevant signaling pathways on mechanisms of HIV reservoir cell survival and death, with a particular focus on the central nervous system and myeloid reservoirs. Studies using biological samples from individuals who use addictive substances (nicotine, cocaine, stimulants, opioids, prescription drugs, cannabinoids, alcohol, or combinations) are highly encouraged.
A word of caution: If you propose any of the following, your application will be deemed nonresponsive and will not be reviewed:
- Studies focused primarily on improving latency reversal
- Studies focused primarily on enhancing effector cell killing
- Approaches designed to bypass cellular mechanisms for eradication, such as HIV-specific antibodies or immunotoxins
- Applications that do not include primary cells from HIV/SIV-infected hosts
- Applications proposing clinical trials
Award Information and Application Due Date
NIAID and partner components intend to fund three to six awards in fiscal year 2023.
