Opportunity Summary:

The grant opportunity titled "Toward An Improved Understanding of HDL Function, NHLBI (R01)" (Funding Opportunity Number PA 11 012) was a National Institutes of Health (NIH) initiative under the National Heart, Lung, and Blood Institute (NHLBI) focused on moving beyond simple measurements of HDL cholesterol levels and toward a clearer, more practical understanding of what HDL actually does in the body. The central idea behind this funding call is that HDL quantity alone has not been sufficient to explain cardiovascular risk or therapeutic benefit, so the field needs stronger, standardized ways to measure HDL function and to connect those functional readouts to underlying biology, genes, and potential interventions.

This FOA encouraged R01 research grant applications aimed at developing, validating, and standardizing laboratory assays that can reliably measure different functional properties of HDL. A key emphasis was on assays and biomarkers that capture HDL performance in biologically meaningful ways, rather than relying on static HDL-C concentration. The announcement specifically highlighted interest in innovative methods to assess functional endpoints such as in vivo reverse cholesterol transport (RCT), as well as HDL's anti-oxidant, anti-inflammatory, and anti-thrombotic activities. In practical terms, the program was seeking tools and approaches that could be used consistently across studies and laboratories, supporting comparability, reproducibility, and eventual clinical translation.

In addition to assay and biomarker development, the FOA also welcomed projects designed to identify novel genes, molecular pathways, and mechanistic targets that influence HDL function. This includes research that digs into how HDL particles achieve their protective effects, what molecular components or pathways enhance or impair those effects, and how those insights could be leveraged to define new therapeutic strategies. The scope therefore covered both methodology (how to measure HDL function well) and discovery science (what controls HDL function and how it can be modified). The opportunity also explicitly encouraged projects exploring HDL functional pathways and the discovery of new genes and therapeutics related to HDL function, signaling that applications could reasonably range from assay engineering and validation studies to mechanistic studies that connect HDL function with disease processes and intervention targets.

Administratively, this was a discretionary grant opportunity using the NIH R01 mechanism, categorized under health research with the CFDA listing 93.837 (Cardiovascular Diseases Research). It did not require cost sharing or matching funds. The FOA was posted on October 25, 2010, and had an original and current closing date of May 7, 2011, after which it was archived on June 7, 2011. While the opportunity itself is no longer open, the description reflects the priorities at the time: improving rigor and standardization in HDL functional measurements and enabling more actionable biological conclusions about HDL in cardiovascular disease.

Eligibility was broad and included many common NIH-eligible applicant types across government, academia, nonprofit, and industry. Eligible applicants included state, county, city, and special district governments; public and state-controlled and private institutions of higher education; independent school districts; public housing authorities/Indian housing authorities; small businesses; for-profit organizations other than small businesses; and nonprofits with or without 501(c)(3) status (with distinctions noted in the FOA). The FOA also specified additional eligible applicant categories such as historically Black colleges and universities (HBCUs), Hispanic-serving institutions, Alaska Native and Native Hawaiian-serving institutions, tribally controlled colleges and universities (TCCUs), faith-based or community-based organizations, U.S. territories or possessions, regional organizations, and non-U.S. entities (foreign organizations). This wide eligibility set underscored the expectation that progress in HDL functional assays and discovery could come from multiple sectors, including academic laboratories, clinical research groups, and technology-driven assay developers.

FAQs: Toward An Improved Understanding of HDL Function, NHLBI (R01) - PA-11-012

What is the grant opportunity "Toward An Improved Understanding of HDL Function, NHLBI (R01)"?

This was a National Institutes of Health (NIH) funding opportunity issued by the National Heart, Lung, and Blood Institute (NHLBI) to support R01 research projects focused on understanding what HDL does in the body (HDL function), rather than relying only on HDL cholesterol (HDL-C) levels.

What was the main purpose of this funding call?

The central purpose was to move beyond simple measurements of HDL quantity (HDL-C concentration) because HDL-C alone had not been sufficient to explain cardiovascular risk or therapeutic benefit. The FOA prioritized developing stronger, standardized ways to measure HDL function and connect those functional readouts to biology, genes, and potential interventions.

What funding mechanism did this opportunity use?

This opportunity used the NIH R01 research project grant mechanism.

What kinds of projects were encouraged under this FOA?

The FOA encouraged R01 applications that developed, validated, and standardized laboratory assays and biomarkers capable of reliably measuring different functional properties of HDL in biologically meaningful ways. It also welcomed studies identifying genes, molecular pathways, and mechanistic targets that influence HDL function.

Why did the FOA emphasize HDL function instead of HDL-C levels?

The FOA was based on the idea that measuring HDL quantity alone (HDL-C) does not adequately capture HDL's protective roles or predict cardiovascular outcomes consistently. The goal was to develop functional measurements that better reflect how HDL behaves biologically and how it may be affected by genes or interventions.

What specific HDL functional endpoints were highlighted as areas of interest?

The announcement highlighted interest in innovative methods to assess endpoints such as in vivo reverse cholesterol transport (RCT), as well as HDL's anti-oxidant, anti-inflammatory, and anti-thrombotic activities.

Did the FOA focus only on assay development?

No. In addition to assay and biomarker development, the FOA welcomed discovery-focused projects aimed at identifying novel genes, molecular pathways, and mechanistic targets that influence HDL function and could point toward new therapeutic strategies.

What was meant by "standardization" and why was it important?

Standardization referred to developing assays and approaches that could be used consistently across studies and laboratories. This was important to support comparability and reproducibility of findings and to help enable eventual clinical translation.

What types of institutions were eligible to apply?

Eligibility was broad and included many NIH-eligible applicant types across government, academia, nonprofit, and industry. Examples listed in the FOA included state, county, city, and special district governments; public and state-controlled and private institutions of higher education; independent school districts; public housing authorities/Indian housing authorities; small businesses; for-profit organizations other than small businesses; and nonprofits with or without 501(c)(3) status (with distinctions noted in the FOA).

Were minority-serving institutions and community-based organizations eligible?

Yes. The FOA listed additional eligible applicant categories such as historically Black colleges and universities (HBCUs), Hispanic-serving institutions, Alaska Native and Native Hawaiian-serving institutions, tribally controlled colleges and universities (TCCUs), and faith-based or community-based organizations.

Could non-U.S. organizations apply?

Yes. The FOA included non-U.S. entities (foreign organizations) among the eligible applicant categories.

Was cost sharing or matching required?

No. The opportunity did not require cost sharing or matching funds.

What program area and CFDA listing applied to this FOA?

It was categorized under health research and referenced CFDA 93.837 (Cardiovascular Diseases Research).

When was the FOA posted and when did it close?

The FOA was posted on October 25, 2010. The original and current closing date was May 7, 2011. It was archived on June 7, 2011.

Is this funding opportunity still open?

No. The closing date passed in 2011 and the FOA has been archived.

What did NHLBI appear to be trying to enable long-term through this program?

Based on the FOA description, the program aimed to improve rigor and standardization in HDL functional measurements and support more actionable biological conclusions about HDL in cardiovascular disease, including insights that could guide new therapeutic strategies.
