Disruption of T cell activation signals induce autoimmune neuropathy in the NOD mouse. Autoimmune neuropathy can be induced in the NOD mouse after modulation of one of the three T cell activation signals. More specifically, mutations in AIRE transcription factor expression in medullary thymic epithelial cells (mTECs) indirectly impact signal 1. In addition, disruptions in co-stimulation signals, such as ICOS/ICOSL and CD28/CD80-86 (signal 2), or neutralization of IL-2 (signal 3) induce autoimmune neuropathy in the NOD mouse.
