Features and Uniqueness
  • McH/lpr-RA1 mice are recombinant congenic mice descended from MRL/lpr and C3H/lpr mice and develop arthritis, vasculitis, and sialadenitis with high frequency and severity, with severe pannus formation similar to rheumatoid arthritis, polyarteritis nodosa, and Sjogren's syndrome. On the other hand, McH/lpr-RA1 mice do not develop systemic lymphadenopathy and severe nephritis as seen in MRL/lpr mice, so they are easy to breed and maintain and can be used for long-term drug administration experiments.
Practical Application

Development of diagnostic and therapeutic agents for collagen 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, etc. Industry-academia collaboration with pharmaceutical companies, test reagent companies, etc. is possible.
