Dynamics of antigen-specific regulatory T-cells in the context of autoimmunity.

Naturally occurring regulatory T-cells (nT-reg) are crucial in preventing generalized autoimmunity. However, antigen-specific T-reg responses during organ-specific autoimmunity have not been characterized until recently when novel tools including MHC class II-tetramers and Foxp3gfp "knock-in" reporter mice (Foxp3gfp.KI) became available. In this review, we… (More)
