Word/Terms List Allergens Atopy Erythroblastosis fetalis Reagin Rhogam Serum sickness Tuberculin skin test

Slide 3 -

Hypersensitivity and Allergy Hypersensitivity-An exaggerated immune response that may cause damage to the host. The trigger is often an innocuous antigen Allergy-A hypersensitive response to an environmental antigen. Often presents as “hay fever”, asthma, dermatitis or anaphylaxis.

Slide 4 -

Four types of Hypersensitivity Type I IgE-mediated e.g.most common allergies Type II IgG-mediated e.g.ABO transfusion reaction

Slide 5 -

Four types of Hypersensitivity Type III Immune-complex mediated e.g.serum sickness Type IV T cell-mediated; delayed type e.g.tuberculin reaction

Type I Hypersensitivity Allergens Proteins Low molecular weight, soluble Atopy-Predisposition to type I hypersensitivity Higher levels of circulating IgE Greater numbers of eosinophils

Slide 8 -

Type I Hypersensitivity Mechanism Allergen is recognized by naïve B cell B cell stimulated by T helper cell through IL4 IgE specific for allergen is recognized by mast cell Cross linkage of IgE on mast cells Mast cell degranulates

Mast Cell Degranulation Leukotrienes Smooth muscle contraction; vascular permeability Platelet activating factor Activates platelets Histamine Vascular permeability; smooth muscle contraction Cytokines IL4- Stimulates T helper response IL3- Activates eosinophils TNF- Promotes inflammation Chemokines MIP- Attracts macrophages

Mast Cell Receptors Fc epsilon RI Ig superfamily Alpha, beta and gamma chains Alpha chain Two Ig like domains; extracellular Gamma chain Homodimer; two intracytoplasmic tails ITAMs Cross linkages activates PTKs Cell signaling leads to degranulation

Prausnitz-Kustner Reaction Described in 1921 Injected allergen caused specific local reaction (Wheal and flare) Called reagins Later identified in 1960’s to be new class of antibody Rabbit Ab against serum from ragweed sensitive individuals could neutralize allergic reaction

Type II Hypersensitivity Drug induced hemolytic anemia Some antibiotics can be antigenic Bind nonspecifically to RBC surface proteins Ab fixes C and lyses RBCs

Slide 23 -

Type III Hypersensitivity Soluble antigens complexed with Ab Deposit in tissue or on walls of blood vessels C activation Mast cell binds Fc; degranulates Fc gamma RIII receptors Neutrophils drawn to area; release of lytic enzymes cause type III reaction

Slide 24 -

Type III Hypersensitivity Serum Sickness Response to foreign protein in serum,e.g horse serum (tetanus antitoxin) Deposition of immune complexes systemically Systemic reactions Fever, vasculitis, arthritis, nephritis
