Below is a video and synopsis of the talk “Role Of T-Regulatory Cells In Immune Modulation” by Dr. Maria Roncarolo at the Vera Moulton Wall Center for Pulmonary Vascular Disease: Summary Standard treatment of immune mediated diseases involves anti-inflammatory and immunosuppressive drugs. By doing this, you downregulate the physiological mechanism to counteract inflammation and adaptive immune responses to self-antigens. Almost all immunosuppressive drugs block T-regulatory cell induction and function. Tolerance is not a lack of immune response, it is just a different type of immune response that the immune system puts in place when we want to tolerize an antigen (self
