Opportunity Summary:

The NIH grant opportunity "Toward an Improved Understanding of HDL Function (R01)" (Funding Opportunity Number PA-12-143) is a discretionary research grant designed to push the field beyond simply measuring HDL cholesterol levels and toward a clearer, more practical understanding of what HDL actually does in the body. The core focus is on HDL function: how HDL particles carry out protective activities that may influence cardiovascular disease risk, and how those activities can be measured reliably across studies and laboratories. The announcement emphasizes that progress in this area depends on better tools and shared standards, so it specifically encourages projects that develop, validate, and standardize laboratory and translational assays that can quantify HDL functional properties and identify biomarkers that reflect those functions.

A central theme of the opportunity is improving how researchers measure multiple HDL functional activities that are thought to matter in cardiovascular biology. The FOA highlights innovative approaches to assessing in vivo reverse cholesterol transport (RCT), which is the process by which cholesterol is moved out of peripheral tissues (including artery wall macrophages) and ultimately handled by the liver for excretion. In addition to RCT, the announcement calls out HDL-related anti-oxidant, anti-inflammatory, and anti-thrombotic activities as important functional domains where improved measurement methods are needed. In practice, this means applicants are encouraged to propose new assays, refine existing ones, and demonstrate that these assays are accurate, reproducible, and suitable for broader adoption. Just as importantly, the opportunity is interested in biomarkers for HDL function, meaning measurable biological indicators (molecular, cellular, or biochemical) that can serve as proxies for functional HDL behavior in research and, potentially, in clinical settings.

The FOA also encourages discovery-oriented work aimed at identifying new pathways and potential HDL targets connected to HDL function. This includes exploring novel functional mechanisms of HDL particles, the proteins and lipids that give HDL its diverse activities, and the molecular pathways through which HDL interacts with immune cells, endothelial cells, platelets, and other relevant tissues. The announcement makes clear that the intent is not only to create better readouts of HDL function, but also to uncover previously unrecognized biology that might explain why HDL behaves differently across individuals, disease states, and therapeutic interventions. Projects that connect these mechanistic findings to therapeutic ideas are explicitly welcomed, including research that explores HDL-related pathways as drug targets, or evaluates interventions intended to improve HDL function rather than simply raising HDL-C levels.

From an administrative standpoint, this is an R01 mechanism, meaning it supports substantial, hypothesis-driven research projects that can include method development, validation studies, and mechanistic investigations, as long as they align with the program goals around HDL functional assays, biomarkers, and pathways. The program is categorized under Health, with a CFDA listing of 93.837 (Cardiovascular Diseases Research). There is no cost sharing or matching requirement, which lowers barriers for many applicants and aligns with standard NIH research grant practices.

Eligibility is broad and includes a wide range of domestic and international organizations. Eligible applicants span state and local governments, federally recognized and other tribal entities, public and private institutions of higher education, nonprofit organizations (both 501(c)(3) and non-501(c)(3) in certain cases), small businesses, and other for-profit organizations (other than small businesses). The announcement also explicitly includes institutions and organizations serving specific populations, such as HBCUs, Hispanic-serving institutions, Alaska Native and Native Hawaiian-serving institutions, and tribally controlled colleges and universities, as well as faith-based and community-based organizations where appropriate. Importantly, foreign institutions are eligible to apply, foreign components are allowed, and non-U.S. components of U.S. organizations may participate, consistent with NIH policy on foreign involvement.

Key dates for this specific posting show it was originally posted and created on March 28, 2012, with an original and current closing date of September 7, 2012, and an archive date of October 8, 2012. While those dates indicate the specific announcement has been archived, the scientific priorities it reflects remain useful as a guide to what NIH sought to advance in HDL research at that time: standardized and meaningful measures of HDL function, credible biomarkers tied to function, and deeper biological insight that could point toward new therapeutic strategies.

What does the FOA mean by focusing on "HDL function" rather than HDL-C?

Instead of focusing on how much HDL cholesterol (HDL-C) is present, the FOA emphasizes measuring what HDL particles actually do biologically, including protective activities relevant to cardiovascular biology, and establishing measurements that are accurate and reproducible across labs.

What kinds of projects are specifically encouraged?

The FOA specifically encourages projects that develop, validate, and standardize laboratory and translational assays that can quantify HDL functional properties. It also encourages efforts to identify biomarkers that reflect HDL functions.
