R01 Research Project Grant
The goal of this notice of funding opportunity (NOFO) is to encourage research to explore mechanisms of inflammasome activation and their link to neurocognitive disorder (NCD) and immune function in people with HIV and substance use disorders (SUDs). This NOFO supports studies to (1) elucidate the role and the underlying mechanisms of inflammasomes in virus and drug-induced immune activation, (2) identify molecular markers associated with inflammasome pathways in NCD and 3) illuminate the cellular and tissue microenvironments that influence inflammasomes in HIV-1 infection or disease progression among individuals with SUD. The overall goal of this program is to facilitate translation of inflammasome research findings into therapeutic tools that improve clinical outcomes in people with HIV.

HIV-1 penetrates the blood brain barrier, infects myeloid cells, and promotes a cascade of inflammatory responses including the formation of inflammasomes. Inflammasomes are a complex of high molecular weight proteins within the cytosol of immune-stimulated cells that mediate the activation of inflammatory cascades. Recent evidence suggests that chronic drug exposure can induce inflammasome activation primarily mediated by the NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3). Additionally, emerging data suggest that HIV-1 infection can also prime inflammasome-mediated neuroinflammation. It has been shown that the use of addictive substances, especially in association with HIV-1 infection, induces reactive oxygen species (ROS) production, impairs blood brain barrier integrity, and promotes monocyte transmigration. These upstream events exert synergistic effects that prime oligomerization and activation of inflammasomes with consequent release of pro-inflammatory cytokine IL-1 beta.
Neuroinflammation in response to HIV infection initiates central nervous system (CNS) innate and adaptive immune activation, including triggering myeloid cells to produce inflammasomes. The diverse CNS myeloid populations, including parenchymal microglia and perivascular macrophages, as well as choroid plexus and meningeal macrophages, dendritic cells, and granulocytes, play an essential role in CNS homeostasis and various neurological pathologies. Research exploring inflammasome and CNS immune functions pertinent to myeloid cells in the context of addictive substance use and HIV infection is of particular interest.
Antibody-mediated enhancement of HIV infection/replication following B-cell responses can result in depletion and blunted recovery of CD4+ T-cells and poor immune recovery despite suppressive antiretroviral therapy (ART). How these immune components in the context of HIV infection and substance use disorder (SUD) contribute to the pathology of both conditions represents a significant knowledge gap. Studies focused on inflammasome cascades and pathogenic antibodies mediated by chronic substance use and HIV infection are warranted.
This notice of funding opportunity (NOFO) invites applications to investigate the underlying mechanisms and CNS consequences of the interactions of addictive drugs and HIV-1 infection on inflammasome assembly and activation. It is important to understand how the involvement of myeloid cell-regulated inflammasome activation, interactions between myeloid cells and neurons, as well as other CNS resident cells, impact processes such as HIV-1 infection, latency, or disease progression among substance using populations.
Basic and preclinical research projects are appropriate. Substances of interest include: opioids, nicotine, cocaine, methamphetamine, stimulants, psychedelics, addictive prescription drugs, cannabinoids, or combinations of these substances.
The NOFO invites applications to investigate the underlying mechanisms and CNS consequences of myeloid cell-triggered inflammasome activation in the context of comorbid HIV-1 infection and acute or chronic substance use. Research areas that are pertinent to this NOFO include, but are not limited to:
