The pathogenesis of urticaria.

T M Keahey

    Dermatologic Clinics
    |January 1, 1985
    PubMed
    Summary
    This summary is machine-generated.

    Urticaria pathogenesis involves multiple mechanisms, not a single cause. Mast cells and inflammatory mediators are key players in urticarial reactions, driving the tissue response.

    Area of Science:

    • Immunology
    • Dermatology
    • Pathophysiology

    Background:

    • Urticaria pathogenesis is complex, involving various initiating factors.
    • Understanding effector pathways is crucial for comprehending urticarial reactions.

    Purpose of the Study:

    • To provide an overview of major effector pathways in urticarial reactions.
    • To emphasize the role of mast cells and inflammatory mediators.

    Main Methods:

    • Literature review and synthesis of current knowledge on urticaria pathogenesis.
    • Focus on pathobiologic events and cellular mechanisms.

    Main Results:

    • Urticarial reactions result from a complex interplay of multiple pathogenetic mechanisms.
    • Mast cells are central to the inflammatory cascade, releasing various mediators.

    Conclusions:

    • No single mechanism fully explains urticaria pathogenesis.
    • Mast cell activation and mediator release are critical in defining the urticarial tissue reaction.
