Opportunity Summary:

The grant opportunity titled "Mouse Models Containing Human Alleles: Novel Tools to Study Brain Function (R21/R33)" (Funding Opportunity Number PAR-08-158) is an NIH funding announcement designed to push forward the creation of new mouse models that carry human genes or human genetic elements. The central idea is to support research tools that more closely mirror human biology in order to clarify how specific genes and gene regulatory components shape brain function. These models are meant to help researchers move beyond broad associations and instead test how particular human gene variants, as well as gene dosage changes (such as deletions, duplications, or altered copy number), actually affect physiology and behavior in ways that may contribute to mental disorders, substance use disorders and addiction, neurodegenerative conditions associated with aging, and alcohol use disorder, including related comorbid conditions.

This program is sponsored by multiple NIH Institutes that share an interest in brain- and behavior-related disease mechanisms: the National Institute of Mental Health (NIMH), the National Institute on Aging (NIA), the National Institute on Alcohol Abuse and Alcoholism (NIAAA), and the National Institute on Drug Abuse (NIDA). That combination signals that the mouse models proposed under this FOA should be broadly useful across psychiatric, addiction, and aging-related neurobiology, and that they should be built and characterized in a way that makes them informative for mechanistic studies rather than being purely descriptive.

Funding is provided through the NIH Exploratory/Developmental Phased Innovation mechanism (R21/R33). This is a two-stage structure where applicants submit one application that includes both phases, but the work is intentionally staged. The first stage (R21) supports early development and feasibility work, such as generating the model, demonstrating that the human allele or human genetic element is correctly introduced and expressed, and establishing initial validation data. The second stage (R33) is intended for the next step of the project once the R21 milestones are met, supporting expanded characterization and deeper analysis of the model, such as more comprehensive molecular, cellular, physiological, and potentially behavioral profiling relevant to brain function and disease mechanisms. Practically, the phased structure is meant to reduce risk for both the applicant and NIH by funding ambitious model development while still requiring clear progress before moving into the more advanced phase.

The FOA emphasizes both development and characterization, which matters because NIH is not only paying for a new strain to be created, but also for evidence that the model works as intended and is informative. In this context, "humanized" mouse models can include mice engineered to carry human coding variants, human regulatory DNA elements that control when and where genes are expressed, or other human genetic components that may influence gene function in the brain. The specific motivation is that many risk signals in human studies involve subtle sequence variation or dosage changes, and mouse models that incorporate those human elements can provide a controlled way to test causal effects and map biological pathways.

The award details in the source information describe it as a discretionary grant program in the health category (CFDA 93.242, Mental Health Research Grants) with no cost-sharing or matching requirement. The listed award ceiling is $150,000, and awards depend on the availability of funds and the quality and volume of applications received, which is standard language indicating there is no guaranteed number of awards. The announcement was posted April 24, 2008, created December 5, 2008, and had an original and current closing date of January 28, 2011, with an archive date of February 28, 2011, meaning it is a historical funding opportunity rather than an active one today.

Eligibility is broad and includes many types of institutions and organizations. Eligible applicants include public and private institutions of higher education, nonprofit organizations (including those with and without 501(c)(3) status), for-profit organizations (other than small businesses as well as small businesses), and a range of government entities such as state, county, city/township, special district governments, and independent school districts. The eligibility list also explicitly includes tribal organizations (federally recognized and other than federally recognized), tribally controlled colleges and universities, U.S. territories or possessions, public housing authorities/Indian housing authorities, and regional organizations. Importantly, the FOA also allows non-U.S. entities (foreign organizations) and federal agencies as eligible applicants, and it calls out categories such as HBCUs, Hispanic-serving institutions, and Alaska Native and Native Hawaiian-serving institutions, reinforcing that a wide range of research organizations could apply.

Frequently Asked Questions (FAQs)

What is the title and funding opportunity number for this grant?

The opportunity is titled "Mouse Models Containing Human Alleles: Novel Tools to Study Brain Function (R21/R33)" and the Funding Opportunity Number is PAR-08-158.

What is the main purpose of PAR-08-158?

This NIH funding announcement is intended to advance the development of new mouse models that carry human genes or human genetic elements. The aim is to create research tools that better reflect human biology so researchers can test how specific human gene variants, regulatory components, and gene dosage changes influence brain function and related disease mechanisms.

What kinds of scientific questions are these mouse models intended to address?

The models are meant to help move beyond broad genetic associations by enabling controlled tests of causality. In particular, they are positioned to examine how specific human alleles, regulatory DNA elements, or dosage changes (for example deletions, duplications, or altered copy number) affect molecular, cellular, physiological, and potentially behavioral outcomes relevant to brain function.

What disease areas are highlighted in the announcement?

The announcement highlights relevance to mental disorders, substance use disorders and addiction, neurodegenerative conditions associated with aging, and alcohol use disorder, including related comorbid conditions.

Which NIH Institutes sponsor this program?

The program is sponsored by multiple NIH Institutes: the National Institute of Mental Health (NIMH), the National Institute on Aging (NIA), the National Institute on Alcohol Abuse and Alcoholism (NIAAA), and the National Institute on Drug Abuse (NIDA).

What does the R21/R33 mechanism mean for applicants?

This opportunity uses the NIH Exploratory/Developmental Phased Innovation mechanism (R21/R33). Applicants submit one application that includes two phases. The first phase (R21) supports early development and feasibility work, while the second phase (R33) supports expanded characterization and deeper analysis after R21 milestones are met.

What activities are typically supported in the R21 phase under this FOA?

Based on the description provided, the R21 phase supports early development and feasibility activities such as generating the mouse model, confirming that the human allele or human genetic element is correctly introduced and expressed, and producing initial validation data.

What activities are typically supported in the R33 phase under this FOA?

Based on the description provided, the R33 phase is intended for the next stage once R21 milestones are achieved, supporting expanded characterization of the model. This can include more comprehensive molecular, cellular, physiological, and potentially behavioral profiling relevant to brain function and disease mechanisms.

Why does the FOA emphasize both development and characterization?

The announcement emphasizes that NIH is not only supporting the creation of a new strain, but also supporting evidence that the model is correctly built, works as intended, and is informative for mechanistic studies rather than being purely descriptive.

What does "humanized" mean in the context of this opportunity?

In this context, "humanized" mouse models can include mice engineered to carry human coding variants, human regulatory DNA elements that control when and where genes are expressed, or other human genetic components that may influence gene function in the brain.

What is meant by gene dosage changes in this announcement?

The information provided references gene dosage changes such as deletions, duplications, or altered copy number. The intent is to enable studies of how these dosage differences may affect physiology and behavior in ways relevant to brain function and disease mechanisms.
