Loss of SDF-1 receptor expression during positive selection in the thymus.

abstract：:Evidence from several different experimental systems suggests that regulatory cells specific for self-antigens exist in the normal immune repertoire, and that these cells are necessary for maintenance of self-tolerance and prevention of autoimmune disease. We attempted to demonstrate the existence of regulatory cells ...
