RT Journal Article T1 Enhancing Regulatory T Cells to Treat Inflammatory and Autoimmune Diseases A1 Fiyouzi Alipour, Tara A1 Peláez Prestel, Héctor Fernando A1 Reyes Manzanas, Raquel A1 Lafuente Duarte, María Esther A1 Reche Gallardo, Pedro Antonio A2 Renaudineau, Yves AB Regulatory T cells (Tregs) control immune responses and are essential to maintain immune homeostasis and self-tolerance. Hence, it is no coincidence that autoimmune and chronic inflammatory disorders are associated with defects in Tregs. These diseases have currently no cure and are treated with palliative drugs such as immunosuppressant and immunomodulatory agents. Thereby, there is a great interest in developing medical interventions against these diseases based on enhancing Treg cell function and numbers. Here, we give an overview of Treg cell ontogeny and function, paying particular attention to mucosal Tregs. We review some notable approaches to enhance immunomodulation by Tregs with therapeutic purposes including adoptive Treg cell transfer therapy and discuss relevant clinical trials for inflammatory bowel disease. We next introduce ways to expand mucosal Tregs in vivo using microbiota and dietary products that have been the focus of clinical trials in various autoimmune and chronic-inflammatory diseases.
