NIH Research
  • Solving the puzzle of complex diseases, from
    obesity to cancer, will require a holistic
    understanding of the interplay between factors
    such as genetics, diet, infectious agents,
    environment, behavior, and social structures.
  • Zerhouni SCIENCE VOL 302 October 3, 2003

5
NIH Directions
  • Focus on interdisciplinary teams to solve large
    scientific problems
  • Provide a seed mechanism for high-risk research
  • Create programs to forge public-private
    partnerships
  • NIH Institutes focus on
  • Genomics and gene-environment interactions
  • Sharing of data public data resources

6
NIMH and Mood Disorders
  • Mood disorders (depression and bipolar disorder)
    are highly heritable
  • Non-genetic factors, particularly stress are
    significant in triggering episodes of mood
    disorders
  • Breaking Ground, Breaking Through The Strategic
    Plan for Mood Disorders Research, National
    Institutes of Mental Health, July 2002

7
Influence of Life Stress on Depression (Caspi,
et. al, 2003)
  • Prospective-longitudinal cohort study of stress
    and depression
  • Functional polymorphism in the promoter region of
    the serotonin transporter (5-HTT) gene
  • Individuals with the short allele of the 5-HTT
    promoter polymorphism exhibited more depressive
    symptoms, diagnosable depression, and suicidality
    in response to stress
  • Caspi, A, et. al (2003) Influence of Life Stress
    on Depression, Science, Vol. 301, July 18, 2003

Partnerships for Genomics and Molecular
Epidemiology (PGME)
  • Goal Build a research program that would allow
    us to conduct complex research that illuminates
    the interaction between genetics and the
    environment
  • Took a building block approach
  • Development of internal capabilities and
    experience
  • Partnering with universities and other
    organizations that have complementary capabilities

9
Partnerships for Genomics and Molecular
Epidemiology (PGME)

  • Clinical expertise immunology, vaccine response,
    drug and alcohol abuse, heart disease, pre-term
    labor, microbial systems, pulmonology, etc., high
    performance computing, software development
  • Duke, UNC, NC State, East Carolina, IBM, SAS,
    Alpha-Gamma Inc, Virginia Commonwealth
    University, and from India Institute of
    Statistical Sciences, National Institute of
    Cholera and Enteric Diseases NICED and
    Institute of Molecular Medicine

18
NIAID Program on Immunity to Vaccines/Infections
  • The objective is to understand role of
    polymorphisms in genes of innate and adaptive
    immunity in modulating the response to vaccines
    for two gastrointestinal tract infections
    typhoid and cholera.
  • RTI International
  • Institute of Molecular Medicine
  • National Institute of Cholera and Enteric
    Diseases
  • Duke University

19
Immunity to Vaccines/Infections
  • Collect blood and saliva from 1000 participants
    for each vaccine in Kolkata, India, at days 0, 3,
    and 28
  • Perform vaccine related immunological assays on
    all biospecimens and classify subjects as non-,
    poor-, and good responders using ELISA and
    vibrocidal antibody assays
  • Discover and validate SNP polymorphisms and
    screen all participants DNA for SNPs to 14
    innate immunity genes and genome scans for
    adaptive immunity genes

20
Immunity to Vaccines/Infections
  • Protein/peptide expression of 11 protein
    mediators of innate/adaptive immunity and 22
    proteins involved in cell stimulation and signal
    transduction. Using LC/MS, immunoassay, and flow
    cytometry
  • Also using 2-D gel MS/MS on 100-200 proteins,
    protein isoforms and protein fragments to
    determine more generalized effects of immune
    activation, signal transduction and general
    response to vaccination,
  • Analysis if association between vaccine response
    and SNPs, haplotypes, or protein expression

21
Immunity to Vaccines/Infections
  • Data will be included in a NIAID sponsored data
    system that will integrate data from 5 other
    similar trials
  • Bioinformatics Integration Support System (BISS)

22
Opportunities Abound
  • NC has many resources that can be used to develop
    partnerships
  • Appreciate work that Donna Spoon and others have
    done to create opportunities for sharing
    information and developing partnerships
