Phenotypic and Functional Properties of Tumor-Infiltrating Regulatory T Cells
Regulatory T (Treg) cells maintain immune homeostasis by suppressing excessive immune responses.Treg cells induce tolerance against self- and foreign antigens, thus preventing autoimmunity, allergy, graft rejection, and fetus rejection during pregnancy.However, Treg cells also infiltrate into tumors and inhibit antitumor immune responses, thus inhi
