IMMUNE MECHANISMS OF HUMAN DISEASE May include abstracts focusing on: Studies of the Healthy Human Immune System Translational Research on Human Immune Responses in Disease including Autoimmunity, Inf reactions. Let’s start. The immune system is a system of biological structures and processes within an organism that protects against disease.. . To function properly, an immune system must detect a wide variety of agents, from viruses to parasitic worms, and distinguish them from the organism’s own healthy tissue. . Types of Antigen. Complete Antigen: Substances which can induce antibody formation by themselves. . Haptens: substances which are unable to induce antibody formation on its own but can become immunogenic, i.e., capable of inducing antibodies, when covalently linked to proteins known as carrier proteins..
