Genetic dissection of autoimmune type I diabetes in the BB rat

Research output: Contribution to journalArticle

Abstract

The BB rat is among the best models of insulin−dependent diabetes mellitus — with onset and pathogenesis closely resembling the human disease. One unusual feature is a severe T−cell lymphopenia, which appears to be inherited as a recessive trait controlled by a single gene, Lyp. Based on genetic analysis of several crosses, we show that development of diabetes involves at least three genes: Lyp, which is tightly linked to the neuropeptide Y (Npy) gene on chromosome 4, a gene linked to the major histocompatibility complex (MHC) on chromosome 20, and a third unmapped gene for which the Fischer rat strain carries an allele conferring resistance.
