Abstract

The hypersensitivity of environmental chemicals and natural products has been reviewed. Among environmental chemicals, small molecular weight molecules work as hapten and cause immediate-type and delayed-type hypersensitivity. Among natural products, relatively lower molecular weight protein or glycoprotein (MW 10,000-70,000 kDa) work as allergen and cause mainly immediate-type hypersensitivity. In recent years, amino acid sequence of important natural allergens have been determined, and three-dimensional structure and IgE epitopes of some of these allergens have also been determined. The characteristics of both inhalation and food allergens have been summarized. As for food allergens, the stability of these proteins in simulated gastric fluid(SGF) was one of the most important characteristics. In the last parts, the approach to the assessment of allergenic potential of genetically modified foods has been summarized.

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.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.
