Study Notes
Immune Reactions and Hypersensitivity
- Type IV immune reaction is responsible for tissue injury and disease.
- Autoimmune responses are directed against self-antigens.
- Immunoglobulin E (IgE) is the main immunoglobulin involved in immediate hypersensitivity reactions.
- Type II hypersensitivity is characterized by antibodies directed against cell or tissue antigens.
- Immune complex diseases are disorders that result from the formation of immune complexes between antibodies and soluble antigens in the blood.
- Type IV hypersensitivity is characterized by reactions of T lymphocytes specific for self-antigens or microbes in tissues.

Description
Test your knowledge of hypersensitivity reactions and their role in immune responses. Learn about the immune system's dual nature of defending against infections while also causing tissue injury and disease. Explore the concept of protective immunity and detectable immune responses to antigens.
