Opportunity Summary:

The grant opportunity titled "The Role of Dysbiosis in Cardiovascular, Pulmonary and Hematological Complications During HIV Infection (R01)" (Funding Opportunity Number RFA-HL-17-017) is a National Institutes of Health (NIH) research project grant meant to push forward basic, mechanistic science on how HIV-associated changes in the microbiome may drive serious non-AIDS complications. The central idea is that HIV infection can disrupt the normal balance of microbial communities (dysbiosis), and that this imbalance may trigger or worsen co-morbid conditions affecting the heart, lungs, and blood (often abbreviated as HLB). The announcement is framed around building a strong biological foundation that can later support early translational work, meaning it is primarily about uncovering causes, pathways, and mechanisms rather than immediately testing clinical interventions. It explicitly includes both adult and pediatric HIV populations, reflecting interest in how these processes may differ across age groups and stages of development.

From a scientific scope standpoint, the FOA emphasizes mechanistic investigations that can explain how dysbiosis emerges during HIV infection and how it connects to cardiovascular disease, pulmonary disease, and hematological abnormalities. The intended studies can use a wide range of experimental and computational systems, including in vitro approaches (cell culture and controlled laboratory assays), in vivo models (animal models or other whole-organism systems), ex vivo work (experiments performed on tissues or cells taken from organisms and studied outside the body), and in silico modeling (bioinformatics, computational modeling, and analysis of complex multi-omic datasets). In practice, this invites proposals that might, for example, link microbial shifts to immune activation, inflammation, endothelial dysfunction, coagulation changes, altered metabolites, or microbial translocation and barrier disruption, then trace how those processes contribute to heart, lung, or blood complications seen in people living with HIV.

A major theme of the opportunity is multidisciplinary collaboration, particularly because microbiome research at a mechanistic level often requires combining clinical insight with microbial ecology, immunology, and advanced measurement and analytics. The FOA encourages teams spanning cardiology, pulmonology, hematology, immunology, infectious diseases, microbiology, biotechnology, bioinformatics, and "-omic" sciences (such as genomics, transcriptomics, proteomics, metabolomics, and metagenomics). This is consistent with the reality that teasing apart dysbiosis-related mechanisms usually involves integrating microbial community profiling with host-response measures, functional assays, and sophisticated computational analyses to move beyond correlation toward causation.

On the administrative side, this is a discretionary grant funding opportunity under the U.S. Department of Health and Human Services, administered by NIH, and categorized as a health-related funding activity. The referenced CFDA numbers include 93.233 and several 93.83x programs (93.837, 93.838, 93.839, 93.840), indicating alignment with NIH institutes and programs that support heart, lung, blood, and related biomedical research. The listed award ceiling is $310,000, and the expected number of awards is 5, suggesting a relatively competitive program designed to fund a small set of focused projects aligned with the HIV Microbiome Centers concept.

Eligibility is broad and includes many organization types: state, county, and city or township governments; special district governments; independent school districts; public and state-controlled institutions of higher education; private institutions of higher education; federally recognized Native American tribal governments and other tribal organizations; public housing authorities/Indian housing authorities; nonprofits with and without 501(c)(3) status (outside of universities); for-profit organizations (other than small businesses); small businesses; and other applicants as clarified in the full eligibility text. The opportunity was created on July 11, 2016, with an original closing date of November 8, 2016, indicating this specific FOA cycle is historic, but the summary still captures NIH priorities and the kind of mechanistic microbiome-and-HIV work the agency sought to catalyze at that time.

Overall, the FOA is designed to strengthen the basic science needed to understand why people living with HIV can experience elevated risks of cardiovascular, pulmonary, and hematological complications even in the era of effective antiretroviral therapy. By focusing on HIV-induced dysbiosis and the downstream biological pathways that may connect microbial imbalance to HLB disease, the program aims to generate actionable mechanistic insights that can later inform biomarker development, risk stratification, and the earliest stages of translational strategies to prevent or mitigate HIV-related HLB co-morbidities.

What is the main scientific focus of the FOA?

The FOA focuses on basic, mechanistic science examining how HIV-associated dysbiosis (disruption of normal microbial community balance) may contribute to cardiovascular, pulmonary, and hematological (HLB) complications during HIV infection.

What does "dysbiosis" mean in the context of this funding opportunity?

In this FOA, dysbiosis refers to HIV-associated alterations in the microbiome that disrupt the typical balance of microbial communities, potentially triggering or worsening downstream biological processes linked to heart, lung, and blood complications.

What kinds of health complications are included under "HLB" in this announcement?

HLB refers to cardiovascular disease (heart-related conditions), pulmonary disease (lung-related conditions), and hematological abnormalities (blood-related disorders or dysfunction).

Is the FOA focused on basic research or clinical intervention testing?

The FOA is primarily focused on building a strong mechanistic and biological foundation. It is framed to support basic studies that can later enable early translational work, rather than immediately testing clinical interventions.
