Opportunity Summary:

The funding opportunity titled "Exploiting RNA as a Target for HIV Interventions (R21)" (Funding Opportunity Number PA 15-272) is an NIH discretionary grant program focused on early-stage, exploratory research that treats RNA biology as a central lever for new HIV interventions. The announcement emphasizes three tightly connected scientific goals: first, to better understand how viral and host long non-coding RNAs (lncRNAs) influence HIV replication and disease; second, to turn those lncRNA insights into practical intervention concepts; and third, to use modern RNA structural biology to uncover RNA-based targets that could support new therapies and potentially contribute to a functional cure strategy.

A major theme of the FOA is the regulatory role of both viral and cellular lncRNAs in HIV. Projects responsive to this call would typically examine how lncRNAs shape key parts of the HIV life cycle and clinical behavior, including viral replication dynamics, pathogenesis, establishment and maintenance of latency, host immune responses, and broader patterns of gene expression in infected cells or relevant tissue environments. The underlying idea is that lncRNAs can act as controllers of transcriptional programs, chromatin state, RNA processing, and cellular signaling pathways, which in turn can determine whether HIV actively replicates, remains silent in latent reservoirs, or triggers immune activation and inflammation. By asking applicants to investigate these mechanisms, the FOA is pushing for clearer causal links between specific lncRNAs (viral or host-derived) and concrete HIV outcomes that matter for treatment and eradication efforts.

The second aim moves from understanding to application: using lncRNAs as a basis for novel HIV interventions. This can include proof-of-concept approaches that manipulate lncRNA expression or function to suppress viral replication, destabilize latency, modulate immune activity, or reprogram cellular states to become less permissive to infection. While the announcement text is high-level, the intent is to stimulate innovative, risk-tolerant ideas that might not yet be ready for large clinical translation grants but could open up new therapeutic directions, including RNA-targeted modalities or strategies that indirectly affect HIV by re-tuning host regulatory networks.

The third aim highlights RNA structural biology as a rapidly advancing toolkit for HIV intervention discovery. Rather than focusing only on proteins as drug targets, the FOA encourages researchers to identify functionally important RNA structures, motifs, or conformations that could be targeted to block HIV processes or support a functional cure approach. This could involve mapping RNA structure-function relationships, identifying structural elements essential for replication or latency, and leveraging structural knowledge to guide the discovery of small molecules, antisense strategies, or other agents that selectively disrupt those RNA elements. The emphasis on "functional cure" reflects interest in approaches that achieve long-term control of HIV without continuous antiretroviral therapy, often by addressing latent reservoirs or durable immune containment, and the FOA frames RNA targeting as a plausible route to help reach that outcome.

Administratively, this is an NIH grant using the R21 mechanism, which is commonly used for exploratory and developmental projects. The award ceiling listed is $200,000, and there is no cost sharing or matching requirement. The opportunity was posted June 5, 2015, with a closing date of May 7, 2018, and it was archived June 7, 2018, meaning it is no longer accepting applications under that specific announcement. The funding activity category is Health, and the CFDA program areas referenced include 93.242 (Mental Health Research Grants), 93.855 (Allergy and Infectious Diseases Research), and 93.856 (Microbiology and Infectious Diseases Research), reflecting cross-cutting relevance that spans infectious disease biology, immunology, and related health research domains.

Eligibility is broad and includes for-profit organizations (including small businesses and other than small businesses), nonprofit organizations (including those with and without 501(c)(3) status), public and private institutions of higher education, and multiple levels of government entities (state, county, city/township, special districts, independent school districts), as well as public housing authorities/Indian housing authorities. The FOA also explicitly includes a wide set of 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, AANAPISIs, faith-based or community-based organizations, U.S. territories or possessions, eligible federal agencies, and non-U.S. entities and regional organizations. In practical terms, NIH was aiming to attract a diverse research community and a wide range of institutional capacities to push forward RNA-centered HIV science.

For reference and full details, NIH provided an additional information link to the complete announcement hosted on the NIH grants guide (PA-15-272). For access issues, the contact listed is the NIH Office of Extramural Research (OER) Webmaster at FBOWebmaster@OD.NIH.GOV, which is primarily for technical problems reaching the announcement rather than scientific program questions.
