Hypersensitivities (type I, II, III, IV, V)

Type 1: Plain old allergy (asthma, anaphylaxis, atopy) Type 2: Antibody-dependent, cytotoxic (think of autoimmune hemolytic anemia) Type 3: Immune complex disease (like a lot of the autoimmune conditions: rheumatoid, lupus) Type 4: Delayed/Cell-Mediated (mediated by T cells, T cells are slower to react than antibodies, so this reaction takes a couple days) Type 5: Receptor-mediated autoimmune disease (Graves, myasthenia gravis)
