Program for Autoimmune Disease Intervention
Our vision for this Program is to evaluate new and emerging markers of lymphocyte lineage and function, in combination with new and emerging markers of genetic propensity for autoimmune phenotypes, in patients at all stages of autoimmune disease—from predisposition through disease diagnosis and response to immunotherapy.

• We anticipate that a successful result from this Program will be the widespread use of such profiling tools for early diagnosis, selection of therapy, monitoring of therapy, and design of the next generation clinical trials for T1D, MS, and lupus.
