Flashcards
Autoimmunity
Autoimmunity
Immune responses that target self-antigens, leading to tissue damage and disease.
Immediate Hypersensitivity
Immediate Hypersensitivity
Immune responses that involve the binding of IgE antibodies to mast cells, triggering the release of inflammatory mediators and rapid reactions.
Type II Hypersensitivity
Type II Hypersensitivity
A type of hypersensitivity reaction characterized by antibody-mediated destruction of cells or tissues.

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.
