    ..Polyoma is non-pathogenic in its immunocompetant natural host. Studying its pathogenesis in immunodeficient hosts can provide basic information which can help to understand processes induced by viruses in immunocompromised individuals. ..
  35. IMMUNOREGULATION IN AIDS
    Norman Letvin; Fiscal Year: 2007
    ..C. Fitness relative to wild type viruses. 3. Nondominant SHIV epitope-specific CTL populations. A. Breadth and magnitude. B. Functional repertoire. C. TCR repertoire. 4. Nondominant epitope-specific CTL and control of SIV replication. ..
  36. ENGINEERING SINGLE CHAIN ANTI T CELL RECEPTOR ANTIBODIES
    DAVID KRANZ; Fiscal Year: 2002
    ..This system involves the use of yeast that we have already engineered to display surface scFv-KJ16. Yeast that co-express scFv-KJ16 and scFv-4F10 will be tested for their ability to affect T cell activity in vitro. ..
  37. EVOLUTIONARY MODELS OF THE IMMUNE SYSTEM
    Melvin Cohn; Fiscal Year: 1993
    ..Third, the skeleton of a computerized interactive immune response has been formulated and needs to be refined to incorporate the detailed component outputs of the humoral and cell mediated immune response compartments...
  38. EVOLUTIONARY MODELS OF THE IMMUNE SYSTEM
    Melvin Cohn; Fiscal Year: 1999
    ..can be monitored. By specifying the events (e.g.; expansion of an entity, elimination of an entity), and probability of such changes based on a desired parameter, rudimentary aspects of the a model's predictions can be approximated. ..
  39. Polyomavirus Infection in Immunodedicient Mice
    Eva Szomolanyi Tsuda; Fiscal Year: 2006
    ..These basic questions are important for the design of vaccines with high efficacy. ..
