PURPOSE OF THIS RFA
This initiative will encourage studies to examine the structure,
biology, genetics, physiology and biochemistry of the oral mucosa and
to compare these features with other mucosal surfaces, especially
vaginal and rectal mucosa, in regard to susceptibility or resistance to
human immunodeficiency virus (HIV) infection and replication.
RESEARCH OBJECTIVES
Background
Compared with the risks of becoming infected with HIV through
unprotected rectal/vaginal intercourse, professional needle-stick
injury, or IV drug injection, the relative risk of adults becoming
infected through the oral route appears to be relatively low.
Understanding this resistance in the oral cavity may suggest novel
methods to prevent or diminish HIV infection at other mucosal sites.
The oral mucosa differs from other mucosal surfaces in that it is
generally thicker, composed of both keratinizing and non-keratinizing
stratified squamous epithelial cells, and bathed in saliva. Oral
epithelial cells are rich sources of microbicidal agents and innate
host immune factors. Yet how the oral mucosa resists HIV infection
while serving as a portal for many other types of viruses such as
Epstein-Barr virus or human papillomavirus is undetermined and requires
further research
Thus far, only a few studies suggest that oral epithelial cells may be
infected with and harbor HIV. HIV provirus has been found in the
epithelial tissues of HIV-infected individuals, although any evidence
of a productive infection is limited. HIV may gain access to target
cells via epithelial cell transcytosis or through direct infection from
the apical mucosal surface. HIV infection of subsets of epithelial
cells, inhibition of spread of infectious virions throughout the
epithelium and prevention of a productive HIV infection remain to be
determined. Research is also needed regarding the interaction of
mucosal cells with lymphocytes in the production of a local immune
response against HIV.
Emphasis must be placed on defining the potential barrier function of
the oral mucosa, identifying properties of this mucosal surface that
differ from those of the vagina and rectum, and determine if
differences in mucosal properties are related to enhanced or diminished
infection by HIV. Data from these studies are expected to elucidate
mechanisms of enhancing the protection of mucosal tissues against HIV
infection.
The oral mucosal surface is highly amenable to research; it is a
readily accessible tissue and established sampling and experimental
techniques are currently available. Although the NIDCR supports
research on the production of mucosal innate immune factors,
interactions with salivary components, and infection by viruses such as
EBV, few studies are examining the importance of these tissues in the
potential prevention of HIV infection and AIDS-related oral
manifestations. In particular, more research is needed on the
uniqueness of the oral mucosa, compared to other mucosal surfaces such
as vaginal or rectal tissues, in HIV infection. We anticipate that this
initiative will stimulate additional research in defining the
immunological, genetic, physiological and biochemical aspects of the
oral epithelium that confer susceptibility or resistance to HIV
infections.
Scope
The objective of this RFA is to stimulate research on the mechanisms
responsible for oral mucosal resistance to HIV infection.
Examples of responsive projects include, but are not limited to:
o Compare the structural and biological properties of oral-pharyngeal
mucosa with vaginal and rectal mucosa;
o Compare the anti-HIV capacity of oral mucosa from infants and adults;
o Determine if the oral mucosa possesses novel barrier functions to
retroviruses as compared to other viral pathogens and define these
functions;
o Investigate whether the oral mucosa permits entry, transcytosis,
harboring and shedding of HIV;
o Characterize and compare the genetic and protein profiles of oral
epithelial cells from healthy versus AIDS patients;
o Characterize and compare the cellular and molecular components,
physiology and function of oral epithelial cells from healthy
individuals and AIDS patients;
o Investigate and compare innate and acquired immunology of oral,
vaginal, and rectal mucosal epithelial surfaces as it relates to HIV
infection;
o Identify salivary components that interact with HIV and possibly
control susceptibility of oral epithelium to HIV infection;
o Elucidate the actions of antiretroviral drugs on oral mucosa or
microbicidal activities in the oral cavity and ancillary organs, i.e.
salivary glands, tonsils, etc., as well as in other mucosal sites; and,
o Determine the impact of co-infections, inflammatory diseases, and
tissue injury on mucosal susceptibility.
MECHANISM OF SUPPORT
This RFA will use NIH R01 and R21 award mechanisms. As an applicant
you will be solely responsible for planning, directing, and executing
the proposed project. This RFA is a one-time solicitation. Future
unsolicited, competing-continuation applications based on this project
will compete with all investigator-initiated applications and will be
reviewed according to the customary peer review procedures. The
earliest anticipated award date is April 2004. Applications that are
not funded in the competition described in this RFA may be resubmitted
as NEW investigator-initiated applications using the standard receipt
dates for NEW applications described in the instructions to the PHS 398
application.
This RFA uses just-in-time concepts. It also uses the modular as well
as the non-modular budgeting formats (see
http://grants.nih.gov/grants/funding/modular/modular.htm).
Specifically, if you are submitting an application with direct costs in
each year of $250,000 or less, use the modular format. Otherwise
follow the instructions for non-modular research grant applications.
This program does not require cost sharing as defined in the current
NIH Grants Policy Statement at
http://grants.nih.gov/grants/policy/nihgps_2001/part_i_1.htm.
FUNDS AVAILABLE
The NIDCR intends to commit approximately $1.2 million total cost
(direct cost and applicable facilities and administrative F&A cost) in
FY2004 or FY2005 to fund four to six new and/or competitive
continuation grants in response to this RFA. An applicant may request a
project period of up to four (4) years and a budget for direct costs up
to $500,000 per year. Because the nature and scope of the proposed
research will vary from application to application, it is anticipated
that the size and duration of each award will also vary. Although the
financial plans of the NIDCR provide support for this program, awards
pursuant to this RFA are contingent upon the availability of funds and
the receipt of a sufficient number of meritorious applications.
ELIGIBLE INSTITUTIONS
You may submit (an) application(s) if your institution has any of the
following characteristics:
o For-profit or non-profit organizations
o Public or private institutions, such as universities, colleges,
hospitals, and laboratories
o Units of State and local governments
o Eligible agencies of the Federal government
o Domestic or foreign
o Faith-based or community-based organizations
INDIVIDUALS ELIGIBLE TO BECOME PRINCIPAL INVESTIGATORS
Any individual with the skills, knowledge, and resources necessary to
carry out the proposed research is invited to work with their
institution to develop an application for support. Individuals from
underrepresented racial and ethnic groups as well as individuals with
disabilities are always encouraged to apply for NIH programs.
SPECIAL REQUIREMENTS
Applicants should request funds for one trip per year for an annual
meeting to be held at NIH in Bethesda, MD. The purpose for these
meetings is to discuss scientific advances in our understanding of the
resistance of the oral mucosa to HIV infection and to discuss the
potential for collaborations, data sharing, data repositories and other
research opportunities.

SUBMITTING AN APPLICATION
Applications must be prepared using the PHS 398 research grant
application instructions and forms (rev. 5/2001). The PHS 398 is
available at http://grants.nih.gov/grants/funding/phs398/phs398.html in
an interactive format. For further assistance contact GrantsInfo,
Telephone (301) 435-0714, Email: GrantsInfo@nih.gov.
SUPPLEMENTAL INSTRUCTIONS FOR R21 APPLICATIONS:
All application instructions outlined in the PHS 398 application kit
are to be followed with the following modifications for R21 applications:
1. FACE PAGE, Item 6: Up to a total of two years of support may be
requested. Total direct costs for the two years may not exceed
$275,000.
2. RESEARCH PLAN: Items a-d may not exceed fifteen (15) pages,
including tables and figures. The following information should be
taken into account for items a, b and c:
o Item a, SPECIFIC AIMS--The instructions for this section suggest
that the applicant state "the hypotheses to be tested". Since some
applications submitted in response to this RFA may also be design- or
problem-driven (e.g., development of novel technologies), or need-
driven (initial research to develop a body of data upon which future
research will build), hypothesis testing per se may not be the driving
force in developing such a proposal and, therefore, may not be
applicable. The application should state the hypotheses, design,
problem and/or need which will drive the proposed research.
o Item b, BACKGROUND AND SIGNIFICANCE--In this section, it is
important to identify clearly how the application addresses the
specific objectives of this RFA and the purpose of the R21 mechanism.
Item c, PRELIMINARY STUDIES/PROGRESS REPORT—No preliminary data are
required for an R21 application.
3. APPENDIX. Up to five articles may be submitted as appendix
materials.
SPECIFIC INSTRUCTIONS FOR MODULAR GRANT APPLICATIONS: R01
applications requesting up to $250,000 per year in direct costs and all
R21 applications must be submitted in a modular grant format. The
modular grant format simplifies the preparation of the budget in these
applications by limiting the level of budgetary detail. Applicants
request direct costs in $25,000 modules. Section C of the research
grant application instructions for the PHS 398 (rev. 5/2001) at
http://grants.nih.gov/grants/funding/phs398/phs398.html includes step-
by-step guidance for preparing modular grants. Additional information
on modular grants is available at
http://grants.nih.gov/grants/funding/modular/modular.htm.
R21 Applications: Applicants may request direct costs in $25,000
modules up to a total of 11 modules ($275,000) over a two year period.
USING THE RFA LABEL: The RFA label available in the PHS 398 (rev.
5/2001) application form must be affixed to the bottom of the face page
of the application. Type the RFA number on the label. Failure to use
this label could result in delayed processing of the application such
that it may not reach the review committee in time for review. In
addition, the RFA title and number must be typed on line 2 of the face
page of the application form and the YES box must be marked. The RFA
label is also available at:
http://grants.nih.gov/grants/funding/phs398/label-bk.pdf.
SENDING AN APPLICATION TO THE NIH: Submit a signed original of the
application, including the Checklist, and three signed, photocopies, in
one package to:
Center For Scientific Review
National Institutes Of Health
6701 Rockledge Drive, Room 1040, MSC 7710
Bethesda, MD 20892-7710
Bethesda, MD 20817 (for express/courier service)
At the time of submission, two additional copies of the application
must be sent to:
H. George Hausch, Ph.D.
Division of Extramural Activities
National Institute of Dental and Craniofacial Research
National Institutes of Health
Building 45, Room 4AN-44F, MSC 6402
Bethesda, MD 20892-6402
APPLICATION PROCESSING: Applications must be received by the
application receipt date listed in the heading of this RFA. If an
application is received after that date, it will be returned to the
applicant without review.
Although there is no immediate acknowledgement of the receipt of an
application, applicants are generally notified of the review and
funding assignment within 8 weeks.
The Center for Scientific Review (CSR) will not accept any application
in response to this RFA that is essentially the same as one currently
pending initial review, unless the applicant withdraws the pending
application. However, when a previously unfunded application,
originally submitted as an investigator-initiated application, is to be
submitted in response to an RFA, it is to be prepared as a NEW
application. That is the application for the RFA must not include an
Introduction describing the changes and improvements made, and the text
must not be marked to indicate the changes. While the investigator may
still benefit from the previous review, the RFA application is not to
state explicitly how.
PEER REVIEW PROCESS
Upon receipt, applications will be reviewed for completeness by the CSR
and responsiveness by the NIDCR. Incomplete and/or non-responsive
applications will be returned to the applicant without further
consideration. Applications that are complete and responsive to the
RFA will be evaluated for scientific and technical merit by an
appropriate peer review group convened by the NIDCR in accordance with
the review criteria stated below. As part of the initial merit review,
all applications will:
o Receive a written critique
o Undergo a process in which only those applications deemed to have the
highest scientific merit, generally the top half of the applications
under review, will be discussed and assigned a priority score
o Receive a second level review by the NIDCR National Advisory Council.
REVIEW CRITERIA
The goals of NIH-supported research are to advance our understanding of
biological systems, improve the control of disease, and enhance health.
In the written comments, reviewers will be asked to discuss the
following aspects of your application in order to judge the likelihood
that the proposed research will have a substantial impact on the
pursuit of these goals:
o Significance
o Approach
o Innovation
o Investigator
o Environment
The scientific review group will address and consider each of these
criteria in assigning your application's overall score, weighting them
as appropriate for each application. Your application does not need to
be strong in all categories to be judged likely to have major
scientific impact and thus deserve a high priority score. For example,
you may propose to carry out important work that by its nature is not
innovative but is essential to move a field forward.
(1) SIGNIFICANCE: Does your study address an important problem? If the
aims of your application are achieved, how do they advance scientific
knowledge? What will be the effect of these studies on the concepts or
methods that drive this field?
(2) APPROACH: Are the conceptual framework, design, methods, and
analyses adequately developed, well integrated, and appropriate to the
aims of the project? Do you acknowledge potential problem areas and
consider alternative tactics?
(3) INNOVATION: Does your project employ novel concepts, approaches or
methods? Are the aims original and innovative? Does your project
challenge existing paradigms or develop new methodologies or
technologies?
(4) INVESTIGATOR: Are you appropriately trained and well suited to
carry out this work? Is the work proposed appropriate to your
experience level as the principal investigator and to that of other
researchers (if any)?
(5) ENVIRONMENT: Does the scientific environment in which your work
will be done contribute to the probability of success? Do the proposed
experiments take advantage of unique features of the scientific
environment or employ useful collaborative arrangements? Is there
evidence of institutional support?
ADDITIONAL REVIEW CRITERIA: In addition to the above criteria, your
application will also be reviewed with respect to the following:
PROTECTION OF HUMAN SUBJECTS FROM RESEARCH RISK: The involvement of
human subjects and protections from research risk relating to their
participation in the proposed research will be assessed. (See criteria
included in the section on Federal Citations, below).
INCLUSION OF WOMEN, MINORITIES AND CHILDREN IN RESEARCH: The adequacy
of plans to include subjects from both genders, all racial and ethnic
groups (and subgroups), and children as appropriate for the scientific
goals of the research. Plans for the recruitment and retention of
subjects will also be evaluated. (See Inclusion Criteria in the
sections on Federal Citations, below).
CARE AND USE OF VERTEBRATE ANIMALS IN RESEARCH: If vertebrate animals
are to be used in the project, the five items described under Section f
of the PHS 398 research grant application instructions (rev. 5/2001)
will be assessed.
ADDITIONAL CONSIDERATIONS
o DATA SHARING: The adequacy of the proposed plan to share data.
o BUDGET: The reasonableness of the proposed budget and the requested
period of support in relation to the proposed research.
o R21 APPLICATIONS: The potential for ground-breaking, precedent-
setting research, with particular emphasis on novel and innovative
approaches; and the potential to stimulate new concepts or approaches
regarding important biomedical/behavioral problems, or provide a
technique/system of wide applicability.

Letter of Intent Receipt Date: August 19, 2003
Application Receipt Date: September 17, 2003
Peer Review Date: October-November 2003
Council Review: January 2004
Earliest Anticipated Start Date: April 2004
AWARD CRITERIA
Award criteria that will be used to make award decisions include:
o Scientific merit (as determined by peer review)
o Availability of funds
o Programmatic priorities
REQUIRED FEDERAL CITATIONS
HUMAN SUBJECTS PROTECTION: Federal regulations (45CFR46) require that
applications and proposals involving human subjects must be evaluated
with reference to the risks to the subjects, the adequacy of protection
against these risks, the potential benefits of the research to the
subjects and others, and the importance of the knowledge gained or to
be gained.
MONITORING PLAN AND DATA SAFETY AND MONITORING BOARD: Research
components involving Phase I and II clinical trials must include
provisions for assessment of patient eligibility and status, rigorous
data management, quality assurance, and auditing procedures. In
addition, it is NIH policy that all clinical trials require data and
safety monitoring, with the method and degree of monitoring being
commensurate with the risks (NIH Policy for Data Safety and Monitoring,
NIH Guide for Grants and Contracts, June 12, 1998:
http://grants.nih.gov/grants/guide/notice-files/not98-084.html).
INCLUSION OF WOMEN AND MINORITIES IN CLINICAL RESEARCH: It is the
policy of the NIH that women and members of minority groups and their
sub-populations must be included in all NIH-supported clinical research
projects unless a clear and compelling justification is provided
indicating that inclusion is inappropriate with respect to the health of
the subjects or the purpose of the research. This policy results from
the NIH Revitalization Act of 1993 (Section 492B of Public Law 103-43).
All investigators proposing clinical research should read the AMENDMENT
"NIH Guidelines for Inclusion of Women and Minorities as Subjects in
Clinical Research - Amended, October, 2001," published in the NIH Guide
for Grants and Contracts on October 9, 2001
(http://grants.nih.gov/grants/guide/notice-files/NOT-OD-02-001.html);
a complete copy of the updated Guidelines are available at http://
grants.nih.gov/grants/funding/women_min/guidelines_amended_10_2001.htm.
The amended policy incorporates: the use of an NIH definition
of clinical research; updated racial and ethnic categories in
compliance with the new OMB standards; clarification of language
governing NIH-defined Phase III clinical trials consistent with the new
PHS Form 398; and updated roles and responsibilities of NIH staff and
the extramural community. The policy continues to require for all NIH-
defined Phase III clinical trials that: a) all applications or
proposals and/or protocols must provide a description of plans to
conduct analyses, as appropriate, to address differences by sex/gender
and/or racial/ethnic groups, including subgroups if applicable; and b)
investigators must report annual accrual and progress in conducting
analyses, as appropriate, by sex/gender and/or racial/ethnic group
differences.
INCLUSION OF CHILDREN AS PARTICIPANTS IN RESEARCH INVOLVING HUMAN
SUBJECTS: The NIH maintains a policy that children (i.e., individuals
under the age of 21) must be included in all human subjects research,
conducted or supported by the NIH, unless there are scientific and
ethical reasons not to include them. This policy applies to all initial
(Type 1) applications submitted for receipt dates after October 1, 1998.
All investigators proposing research involving human subjects should
read the "NIH Policy and Guidelines" on the inclusion of children as
participants in research involving human subjects that is available at
http://grants.nih.gov/grants/funding/children/children.htm.
REQUIRED EDUCATION ON THE PROTECTION OF HUMAN SUBJECT PARTICIPANTS:
NIH policy requires education on the protection of human subject
participants for all investigators submitting NIH proposals for
research involving human subjects. You will find this policy
announcement in the NIH Guide for Grants and Contracts Announcement,
dated June 5, 2000, at
http://grants.nih.gov/grants/guide/notice-files/NOT-OD-00-039.html.
HUMAN EMBRYONIC STEM CELLS (hESC): Criteria for federal funding of
research on hESCs can be found at
http://grants.nih.gov/grants/stem_cells.htm and at
http://grants.nih.gov/grants/guide/notice-files/NOT-OD-02-005.html.
Only research using hESC lines that are registered in the NIH Human
Embryonic Stem Cell Registry will be eligible for Federal funding (see
http://escr.nih.gov). It is the responsibility of the applicant to
provide the official NIH identifier(s)for the hESC line(s)to be used in
the proposed research. Applications that do not provide this
information will be returned without review.
PUBLIC ACCESS TO RESEARCH DATA THROUGH THE FREEDOM OF INFORMATION ACT:
The Office of Management and Budget (OMB) Circular A-110 has been
revised to provide public access to research data through the Freedom of
Information Act (FOIA) under some circumstances. Data that are (1)
first produced in a project that is supported in whole or in part with
Federal funds and (2) cited publicly and officially by a Federal agency
in support of an action that has the force and effect of law (i.e., a
regulation) may be accessed through FOIA. It is important for
applicants to understand the basic scope of this amendment. NIH has
provided guidance at
http://grants.nih.gov/grants/policy/a110/a110_guidance_dec1999.htm.
Applicants may wish to place data collected under this PA in a public
archive, which can provide protections for the data and manage the
distribution for an indefinite period of time. If so, the application
should include a description of the archiving plan in the study design
and include information about this in the budget justification section
of the application. In addition, applicants should think about how to
structure informed consent statements and other human subjects
procedures given the potential for wider use of data collected under
this award.
URLs IN NIH GRANT APPLICATIONS OR APPENDICES: All applications and
proposals for NIH funding must be self-contained within specified page
limitations. Unless otherwise specified in an NIH solicitation, Internet
addresses (URLs) should not be used to provide information necessary to
the review because reviewers are under no obligation to view the
Internet sites. Furthermore, we caution reviewers that their anonymity
may be compromised when they directly access an Internet site.
HEALTHY PEOPLE 2010: The Public Health Service (PHS) is committed to
achieving the health promotion and disease prevention objectives of
"Healthy People 2010," a PHS-led national activity for setting priority
areas. This RFA is related to one or more of the priority areas.
Potential applicants may obtain a copy of "Healthy People 2010" at
http://www.health.gov/healthypeople.
AUTHORITY AND REGULATIONS: This program is described in the Catalog of
Federal Domestic Assistance at http://www.cfda.gov/ and is not subject
to the intergovernmental review requirements of Executive Order 12372
or Health Systems Agency review. Awards are made under the
authorization of Sections 301 and 405 of the Public Health Service Act
as amended (42 USC 241 and 284) and under Federal Regulations 42 CFR 52
and 45 CFR Parts 74 and 92). All awards are subject to the terms and
conditions, cost principles, and other considerations described in the
NIH Grants Policy Statement. The NIH Grants Policy Statement can be
found at http://grants.nih.gov/grants/policy/policy.htm.
The PHS strongly encourages all grant recipients to provide a smoke-
free workplace and discourage the use of all tobacco products. In
addition, Public Law 103-227, the Pro-Children Act of 1994, prohibits
smoking in certain facilities (or in some cases, any portion of a
facility) in which regular or routine education, library, day care,
health care, or early childhood development services are provided to
children. This is consistent with the PHS mission to protect and
advance the physical and mental health of the American people.
