Regulatory T cells (Tregs) are a unique subset of lymphocytes that play a vital role in regulating the immune system by suppressing unwanted immune responses and thus preventing autoimmune diseases and inappropriate inflammatory reactions. In preclinical and clinical trials, these cells have demonstrated the ability to prevent and treat graft vs. host disease, alleviate autoimmune symptoms, and promote transplant tolerance. In this review, we provide a background on Treg cells with a focus on important Treg cell markers and Treg subsets, and outline the methodology currently used for manufacturing adoptive regulatory T cell therapies (TRACT). Finally, we discuss the approaches and outcomes of several clinical trials in which Tregs have been adoptively transferred to patients.
