Project Description

A major obstacle to advances in veterinary immunology and disease control is the lack of sufficient immunological reagents specific for ruminants, swine, poultry, equine, and aquaculture species. Sets of reagents, that is monoclonal antibodies (mAb) and polyclonal antibodies, that identify the major leukocyte subpopulations (T and B lymphocytes, NK cells, macrophages, dendritic cells, neutrophils) are needed. In addition, it is crucial to have recombinant cytokines and chemokines as well as antibodies to them and their receptors to understand their contributions to inflammation and protective immunity.

Reagents to identify immunoglobulin (Ig) isotypes (classes) are needed since antibody isotypes differ from one another functionally and thus with regard to their effect on disease outcome. The reagents produced will include bioactive recombinant cytokines and chemokine proteins expressed using mammalian cells, Pichia pastoris or E. coli systems, as well as antibodies and mAb to them, their receptors, as well as mAb to Ig isotypes, T cell receptors (TCR), Toll like receptors (TLR), and other CD molecules.

These reagents will be used to: (1) evaluate changes during disease and following vaccination and
(2) give scientests the aility to manipulate these cell populations to evaluate their roles in protective immunity as well as in immunopathology.

Development of the above reagents will address the USDA-CSREES National Research Initiative goal of enhancing the safety of the Nation's agriculture and food supply by aiding in the development of vaccines. This presents a broad community plan to begin to systematically address the immunological reagent gap for the U.S. veterinary immunology research community including for the following groups: ruminants (concentrating on cattle primarily, but also evaluating sheep), swine, poultry (primarily chickens with some evaluation of reagents for turkeys), horses, and aquaculture species (concentrating on channel catfish and salmonoid trout, two of the principal economically important species). The goal is to develop 20 reagents per species group minimally, including antibodies that function in ELISA and ELISpot assays, for intracellular staining, for blocking function and signalling, and that are useful in flow cytometric applications, as well as in fixed tissue sections. Products developed in this proposal will benefit a large group of researchers, including veterinary immunologists, pathologists, and microbiologists.

The effort includes a large panel of collaborators, consultants, and advisory board members in addition to the Project Directors. Furthermore, the effort is being coordinated with other international efforts and the Advisory Board includes individuals involved in similar projects in U.K., France, The Netherlands, and Australia.
