Altered neuronal circuits, receptors and networks in HIV-induced Central Nervous System (CNS) dysfunction (R01)-Clinical Trial Not Allowed | RFA MH 18 610

Opportunity Information: Apply for RFA MH 18 610

The National Institutes of Health (NIH) announced this discretionary funding opportunity as an R01 research grant focused on understanding why central nervous system (CNS) problems can persist in people living with HIV-1 even when their virus is well controlled (virally suppressed) on treatment. The scientific emphasis is on the idea that HIV-related CNS dysfunction may be driven not only by broad inflammation or general neurotoxicity, but by specific, measurable changes in how neurons communicate and organize: altered neuronal circuits, altered neuronal receptors, and disrupted neuronal networks. In practical terms, the FOA is looking for studies that can move beyond describing symptoms and instead map out the pathways and mechanisms that cause these changes, and then connect those mechanisms to functional outcomes relevant to cognition, behavior, or neurological performance in the setting of treated HIV.

The opportunity encourages both basic and translational research, meaning applications can range from fundamental lab-based neuroscience (for example, synaptic signaling, receptor biology, circuit mapping, or network dynamics) to work that bridges toward human relevance (for example, biomarker-linked mechanistic studies, ex vivo human tissue work, or translational models that reflect virally suppressed HIV). Studies may be conducted in domestic (U.S.) or international settings, reflecting NIH interest in globally relevant HIV neuroscience and in leveraging cohorts, expertise, and resources wherever they are strongest. While the announcement explicitly encourages multidisciplinary teams and collaborative alliances, it does not require them, so a single institution with the right expertise could apply, but proposals that integrate neuroscience, virology, immunology, imaging, computational/network analysis, and clinical phenotyping may be particularly well positioned to address the mechanistic questions the FOA prioritizes.

A key administrative feature is that this is an R01 with a "Clinical Trial Not Allowed" designation. That generally means the application should not propose a prospective clinical intervention study in humans where participants are assigned to an intervention to evaluate health-related outcomes. The FOA is aimed at mechanistic research rather than testing treatments. Applicants typically need to ensure that any human work proposed fits NIH definitions that do not constitute a clinical trial (for example, observational or mechanistic studies without an assigned intervention), and that any translational elements are designed to uncover causality and pathways rather than evaluate an intervention’s efficacy.

Eligibility is broad. In addition to the standard set of public and private institutions, the FOA lists many organization types that can apply, including state, county, city/township, and special district governments; independent school districts; public housing authorities/Indian housing authorities; federally recognized tribal governments and other tribal organizations; public and state-controlled institutions of higher education; private higher education institutions; nonprofit organizations with or without 501(c)(3) status (excluding higher education institutions in those categories); for-profit organizations other than small businesses; and small businesses. It also explicitly highlights additional eligible applicants such as Historically Black Colleges and Universities (HBCUs), Hispanic-serving institutions, Tribally Controlled Colleges and Universities (TCCUs), Alaska Native and Native Hawaiian Serving Institutions, and Asian American Native American Pacific Islander Serving Institutions (AANAPISIs). Faith-based and community-based organizations are included, as are eligible federal agencies. Importantly, non-U.S. entities (foreign organizations), regional organizations, and U.S. territories or possessions are also eligible, reinforcing the international scope of potential research environments.

From the source details, the funding opportunity title is "Altered neuronal circuits, receptors and networks in HIV-induced Central Nervous System (CNS) dysfunction (R01) - Clinical Trial Not Allowed," with opportunity number RFA-MH-18-610. The sponsoring agency is NIH, and the activity falls under education and health categories, with CFDA numbers listed as 93.242, 93.273, 93.279, and 93.853 (reflecting NIH program areas that may relate to mental health, drug abuse, allergy/infectious diseases, and related research infrastructures). The opportunity was created on 2017-11-07, and the original closing date was 2018-01-08. The award ceiling and expected number of awards are not specified in the provided excerpt, so applicants would typically refer to the full FOA text for budget guidance, project period expectations, and review criteria. Overall, the FOA is a targeted call for mechanistic neuroscience research aimed at explaining persistent HIV-associated CNS dysfunction in the modern era of viral suppression, with a clear push toward identifying causal circuit-, receptor-, and network-level changes that can ultimately inform future diagnostic or therapeutic strategies (even though testing interventions is not part of this particular announcement).
