Nonobese Diabetic Mice (NOD mice) that do not develop diabetes may be bred t o produce F1 offspring that develop a condition that closely mimics rheumatoid arthritis (RA) in humans. The RA-like disease in the F1 mice, designated NOD - RA mice, is similar to human RA in clinical, radiological, histological and serological characteristics. The parents (F0) and their progeny (F1) are not diabetic and never develop hyperglycemia, and the parental mice (F0) do not themselves exhibit any symptoms of the RA-like condition that afflicts some of their progeny. The incidence, penetrance, gender domination, progression, an d lifelong exacerbation of symptoms after pregnancy shown in the RA-like condition afflicting NOD-RA mice are all comparable to phenomena observed in the human disease. The NOD-RA mice provide a new spontaneous model of human RA that will be useful for studying rheumatoid arthristis and testing new drugs and reagents for treating or diagnosing the disease.
