[Emphasis on the T regulatory cells in stabilizing immunology of the eye].

T regulatory cells (Tregs) have been recognized as the hotspot in recent immunology research. Because of the capability of immune suppression, they play an important role in regulating many immune associated diseases. It has been reported that they are involved in stabilizing local immune microenvironment of the eye and regulating many eye diseases such as corneal transplantation immune rejection, uveitis, allergic conjunctivitis, infectious keratitis and dry eye. Treatment with Tregs may provide novel method for immune related eye diseases.
