title: Identifying the degree of major histocompatibility complex matching in genetically unrelated dogs with the use of microsatellite markers.
abstract: BACKGROUND
  The dog has served as an important experimental model for biomedical research such as transplantation and developing immunosuppressive agents. Although major histocompatibility complex (MHC) in dogs is a dominant factor of graft rejection, it has not been well investigated in dogs compared with human. For that reason, imprecise cross-matching or time-consuming sequence-based typing methods have generally been used to choose specific donor and recipient pairs. Investigation of matching distribution of MHC in dogs with the use of simple and accurate methods would be beneficial for biomedical researchers. The aim of this study was to identify the diversity of dog leukocyte antigen (DLA) types in genetically unrelated dogs by means of microsatellite markers.
  
  
  METHODS
  Thirty-three Beagle and Shih-Tzu dogs, which were negative in cross-matching, were chosen. The genomic DNA was isolated from peripheral blood leukocytes, and highly polymorphic short tandem repeats located in MHC class I and II were amplified with the use of specific primers.
  
  
  RESULTS
  Among all of the dogs, MHC matching groups, including class I full match-class II full match (M-M), class I full match-class II haplo match (M-H), class I haplo match-class II full match (H-M), class I haplo match-class II haplo match (H-H) groups, were ∼1.55%, 0.39%, 1.94%, and 6.59%, respectively. MHC class I nonmatch-class II nonmatch (U-U) groups were 58.14% of the total dogs.
  
  
  CONCLUSIONS
  Because differences of histocompatibility between donor and recipient leads to various allograft rejections, knowledge of the distribution of MHC matching in unrelated dogs would be helpful in designing studies and to get more accurate results from experiments using dog transplantation models.
