It has been proposed that the development of insulin-dependent diabetes is controlled by the T helper 1 (TH1) versus TH2 phenotype of autoreactive TH cells: TH1 cells would promote diabetes, whereas TH2 cells would actually protect from disease. This proposition was tested by establishing cultures of TH1 and TH2 cells that express an identical diabetogenic T cell receptor and comparing their ability to initiate disease in neonatal nonobese diabetic mice. TH1-like cells actively promoted diabetes; TH2-like cells invaded the islets but did not provoke disease--neither did they provide substantial protection.
Katz et al. (1995) studied this question.
