  2. Immunoglobulin E - Wikipedia

    en.wikipedia.org/wiki/Immunoglobulin_E

    IgE primes the IgE-mediated allergic response by binding to Fc receptors found on the surface of mast cells and basophils. Fc receptors are also found on eosinophils, monocytes, macrophages and platelets in humans. There are two types of Fcε receptors: [citation needed] FcεRI (type I Fcε receptor), the high-affinity IgE receptor

  4. Immunoglobulin heavy chain - Wikipedia

    en.wikipedia.org/wiki/Immunoglobulin_heavy_chain

    Each heavy chain has two regions: a constant region (which is the same for all immunoglobulins of the same class but differs between classes).. Heavy chains γ, α and δ have a constant region composed of three tandem (in a line next to each other) immunoglobulin domains but also have a hinge region for added flexibility.

  5. Isotype (immunology) - Wikipedia

    en.wikipedia.org/wiki/Isotype_(immunology)

    The IgG, IgE and IgA antibody isotypes are generated following class-switching during germinal centre reaction and provide different effector functions in response to specific antigens. IgG is the most abundant antibody class in the serum and it is divided into 4 subclasses based on differences in the structure of the constant region genes and ...

  6. Radioallergosorbent test - Wikipedia

    en.wikipedia.org/wiki/Radioallergosorbent_test

    The RAST is a radioimmunoassay test to detect specific IgE antibodies to suspected or known allergens for the purpose of guiding a diagnosis about allergy. [10] [11] IgE is the antibody associated with Type I allergic response: for example, if a person exhibits a high level of IgE directed against pollen, the test may indicate the person is allergic to pollen (or pollen-like) proteins.

  7. Atopy - Wikipedia

    en.wikipedia.org/wiki/Atopy

    These IgE antibodies bind to the surface of mast cells via high-affinity IgE receptors, a step that is not itself associated with a clinical response. [13] However, upon re-exposure, the allergen binds to membrane-bound IgE which activates the mast cells, releasing a variety of mediators. [ 13 ]

    The U.S. Food and Drug Administration (FDA) now classifies eggs as a “healthy, nutrient-dense" food, according to a new proposed rule. Registered dietitians react to the change.
