FAQs: NIH PAS-08-178 (R01) - Model Systems for HIV/Lentivirus-Related Nervous System Injury (NeuroAIDS)

What is this funding opportunity?

This is an NIH Funding Opportunity Announcement (FOA) identified as PAS-08-178. It supports NIH Research Project Grant (R01) applications for research projects that build, improve, and validate model systems used to study how HIV and related lentiviruses damage the nervous system (often discussed in the context of NeuroAIDS).

What is the main goal of PAS-08-178?

The core goal is to strengthen and expand the experimental tools (model systems) that scientists use to investigate neurologic complications of AIDS/NeuroAIDS, including understanding mechanisms of nervous system injury and accelerating development and testing of therapeutic strategies.

What types of research are encouraged under this FOA?

The FOA emphasizes development, refinement, and validation of model platforms that reproduce key features of HIV-associated neuropathogenesis. This includes models that better reflect infection processes, immune responses, inflammation, neurodegeneration, and functional neurologic outcomes seen in people living with HIV/AIDS.

What kinds of model systems are within scope?

The scientific scope includes both in vivo animal models and ex vivo cell culture systems, as long as the work is focused on building, improving, or validating systems that reproduce important aspects of HIV-associated nervous system disease biology.

Are animal models specifically important to this FOA?

Yes. The FOA highlights progress in SIV-based research as an example of how powerful well-designed animal models can be for uncovering mechanisms of nervous system injury during lentiviral infection. These models are positioned as essential for both understanding HIV biology in the brain and for developing/testing therapies.

Does the FOA focus only on SIV-based models?

No. SIV-based research is emphasized as a strong example, but the FOA is broadly aimed at any rigorous model development effort that can advance the field, including in vivo and ex vivo systems.

Can projects include drug use or alcohol use as co-factors?

Yes. The FOA explicitly notes interest in models that clarify how neurologic complications may differ in the presence or history of drug use or alcohol use, and it encourages incorporating these co-factors (drugs of abuse and/or alcohol) to reflect clinically relevant scenarios.

What NIH grant mechanism is used for this opportunity?

This FOA uses the NIH Research Project Grant (R01) mechanism, which is generally used for mature, hypothesis-driven projects with substantial scope and a strong preliminary rationale.

Is there a companion opportunity for earlier-stage or higher-risk ideas?

Yes. The FOA is paired with a companion announcement with the same scientific focus that uses the R21 Exploratory/Developmental mechanism (PAS-08-179), which is generally more appropriate for earlier-stage, higher-risk model development concepts.

What if my project is smaller or more limited in scope?

The announcement points applicants with smaller, more limited model development projects toward the NIH R03 Small Research Grant mechanism via a separate program announcement, offering another entry point based on scale and readiness.

Which NIH Institutes are involved in funding this FOA?

Funding is shared across several NIH Institutes with overlapping interests in NeuroAIDS and comorbid substance use, including NINDS, NIDA, NIMH, and participation from NIAAA (subject to merit and funds availability).

How much funding is expected to be available?

NINDS indicates an intent to commit up to $1.5 million in total costs across three years for applications responding to this FOA and its companion FOA. In addition, NIDA and NIMH plan to contribute additional support each year ($500,000 and $400,000 per year, respectively) to these FOAs. NIAAA does not specify a set-aside amount.

Does NIAAA provide a dedicated set-aside for alcohol-related projects?

No. NIAAA participation is described as depending on scientific merit and availability of funds, meaning alcohol-related components may be competitive but there is not a guaranteed dedicated funding pool stated in the information provided.

Who is eligible to apply?

Eligibility is broad and includes: public and private institutions of higher education; nonprofit organizations (with or without 501(c)(3) status); for-profit organizations (other than small businesses); small businesses; and many government entities (state, county, city/township, special district, and independent school districts), as well as public housing authorities/Indian housing authorities.

Are tribal entities and minority-serving institutions eligible?

Yes. The FOA explicitly includes federally recognized and other tribal governments, tribally controlled colleges and universities, HBCUs, Hispanic-serving institutions, Alaska Native and Native Hawaiian-serving institutions, and other community-based and faith-based organizations as eligible applicants.

Are U.S. territories or regional organizations eligible?

Yes. The eligible applicant types include U.S. territories or possessions and regional organizations.

Can foreign (non-U.S.) entities apply?

Yes. The eligibility list explicitly includes non-U.S. (foreign) entities.

Are federal agencies eligible to apply?

Yes. The FOA includes eligible federal agencies among the applicant types.

Is cost sharing or matching required?

No. The FOA states there is no cost sharing or matching requirement, which aligns with typical NIH research grants.

What is the application timeframe for this FOA?

The opportunity was posted on June 18, 2008, with a closing date of May 7, 2011. It was archived on June 7, 2011.

What does it mean that this is a discretionary grant opportunity?

The information provided describes it as a discretionary grant opportunity issued by the National Institutes of Health, meaning awards are made based on NIH processes and priorities rather than an entitlement formula.

What topic areas does this FOA connect to across NIH programs?

The FOA is associated with multiple CFDA programs reflecting participating institutes and topic areas, including neuroscience/neurological disorders, mental health, drug abuse, and alcohol research.

Where can applicants find the official announcement?

The FOA includes a link to the full NIH guide notice. The information also notes that applicants who have trouble accessing the electronic announcement can contact the NIH Office of Extramural Research (OER) webmaster for technical assistance.

What should a strong application emphasize, based on the scope described?

Based on the information provided, a strong application would focus on rigorous development, improvement, or validation of in vivo or ex vivo models that mirror key biologic and functional features of HIV-associated neurologic disease, and may incorporate clinically relevant co-factors like drugs of abuse and/or alcohol to clarify differences in neurologic outcomes and mechanisms.
