Type I (Immediate) hypersensitivity reactions are characterized by the rapid release of preformed mediators such as histamine from mast cells and basophils. This type of reaction is triggered by the binding of allergen-specific IgE antibodies to their receptors on these cells, leading to the activation of the immune response. Common examples of Type I hypersensitivity reactions include allergic rhinitis, asthma, and anaphylaxis.

Type II hypersensitivity reactions, also known as antibody-mediated reactions, involve the binding of antibodies to antigens on the surface of cells or tissues, leading to cell destruction or dysfunction.

    <h3>Type III Hypersensitivity</h3>
    <p>Type III hypersensitivity reactions result from the formation of immune complexes between antigens and antibodies, leading to complement activation and inflammation. This can cause tissue damage in organs like the kidneys (glomerulonephritis) and joints (rheumatoid arthritis).</p>
    
    <h3>Type IV Hypersensitivity</h3>
    <p>Type IV hypersensitivity reactions, also known as delayed-type hypersensitivity reactions, are mediated by T cells rather than antibodies. Upon exposure to an antigen, sensitized T cells release cytokines that recruit and activate macrophages, leading to tissue damage. Examples include contact dermatitis and tuberculin skin tests.</p>
