Description
The NIAID is actively seeking input from the scientific community to assess (1) scientific interest in maintaining certain unique rabbit strains for research purposes, and (2) interest from research or commercial groups in serving as a central facility to continue the breeding and distribution of these strains.
A unique pedigreed rabbit colony was developed and supported for many years at the NIAID, and a relational database containing more than 45 years of breeding records and other information about the animals in the colony was developed and maintained continuously to date. This rabbit colony will be discontinued unless alternative methods are identified to maintain the resource. At a minimum, 60-90 rabbits must be maintained and routinely bred to continue the three specific allotype lines described below, and at the same time prevent inbreeding at other genetic loci. Thus, appropriate veterinary and animal husbandry expertise is needed, as well as genetic typing capability and experience with animal tracking, shipping, and distribution. Basic housing and veterinary care currently require approximately $200,000 per year.
These rabbits have been uniquely valuable for studies on the genetics of the immune system, the regulation of B cell development and differentiation, antibody repertoire development, mucosal immunology, HIV-1 and other infectious diseases, and antibody-mediated autoimmune diseases. They are defined for immunoglobulin allotypes, which are allelic variants of antibody heavy and light chains. Three valuable strains are included in the colony and are designated as b9/b9, ali/ali, and the parental wild type 2R1/2R1. The b9/b9 rabbits were shown to be optimal for production of chimeric rabbit:human monoclonal antibodies with high affinities and specificity for antigen. The mutant ali/ali animals have a deletion in a key variable region gene in the immunoglobulin heavy chain locus that is present in the related wild type 2R1/2R1. These animals may differ in susceptibility to infectious disease because the mutant ali/ali has abnormally delayed development of humoral immunity; B lymphocyte development is delayed and depends heavily on gene conversion. These rabbits also provide a rich source of activation-induced deaminase enzyme and are a potential source for cofactor discovery.
Clearly, rabbits are useful models in a wide variety of additional research areas including cardiovascular, ocular, and neurological diseases. Therefore, antibody allotype markers, or the specific properties of these particular rabbit strains, may be advantageous for study in these areas as well. Furthermore, rabbit genomic information is now available: the rabbit genome has been sequenced at light 2X coverage, the trace archive of the whole genome shotgun sequence is available, and deep sequencing is underway at the Broad Institute. These advances may lead to increased utilization of rabbits in future research.
