Introduction to allergic diseases

Critical Reviews in Food Science and Nutrition

Abstract

Allergic diseases result from IgE-mediated immune responses to foreign protein (allergens). The majority of such reactions are IgE-mediated (type I) reactions. Individuals who develop such reactions are allergic. Those predisposed on a genetic basis to synthesize IgE to environmental allergens are atopic. Most allergic reactions are precipitated when a specific allergen aggregates several IgE molecules attached to IgE receptors on the surfaces of mast cells and basophils. Chemical mediators are released which lead to the immediate signs and symptoms associated with allergic diseases including hives, asthma, and anaphylaxis. More prolonged reactions follow if significant numbers of other cells including eosinophils, macrophages, and lymphocytes are drawn into sites of mast cell activation. Therefore, allergic diseases result from a complex interplay of immune cells, foreign proteins, and tissue inflammation.

Anaphylaxis

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Basophils

Basophils are myeloid cells with a high affinity IgE receptor and is involved in inflammatory responses during allergy. Discover the latest research on Basophils here.
