This document provides an overview of an immunology and immunoinformatics master's program. It summarizes the course outcomes, which include learning about the immune system components, HLA and immune responses, types of hypersensitivity and autoimmune disorders, and immunoinformatics applications. It then provides details on autoimmunity and autoimmune diseases, including the mechanisms of central and peripheral tolerance that normally prevent autoimmunity. It defines autoimmunity as the presence of autoantibodies without pathological changes, while autoimmune diseases involve tissue damage. Criteria for classifying diseases as autoimmune are outlined. Mechanisms of autoimmunity and characteristics of autoimmune diseases are briefly discussed. References used in the document are listed at the end.
