Features and Uniqueness
  • Eleven strains of recombinant inbred (RI) mice derived from MRL/lpr and C3H/lpr mice were established. This RI is the only one in the world that randomly develops lesions such as nephritis, arthritis, sialadenitis, vasculitis, and production of autoantibodies in each strain. The genomes of the two strains of mice are randomly held in homozygous condition, and the phenotypes of each strain and the effects of administered drugs could be compared based on their genotype maps. It is possible to identify the regions of gene loci involved in the phenotype and drug sensitivity.
Practical Application

Development of diagnostic and therapeutic agents for autoimmune diseases. It can be applied to the elucidation of the mechanism of onset of immunological adverse events caused by immune checkpoint inhibitors and the development of drugs to prevent the onset of such events, and industry-academia collaboration with pharmaceutical companies, test reagent companies, etc. is possible.
