Cell-mediated hypersensitivity to mite antigens in atopic dermatitis

Archives of Dermatology
W L EllistonC C Huntley


Cell-mediated hypersensitivity (CMH) to house dust mite antigens, as determined by increased DNA synthesis after coculture of mononuclear cells with Dermatophagoides farinae extract, was demonstrated in 11 of 16 children with atopic dermatitis (AD) as compared with two of 14 control subjects. Patient and control responses peaked at the same antigen dose (12.4 micrograms of mite protein per 10(5) cells). Patient responses were significantly greater at all mite protein concentrations. The increased DNA synthesis of stimulated cells was demonstrated to be a T-cell response in the one patient in whom T-cell-enriched cultures were studied. There was no relationship between CMH and lgE-mediated hypersensitivity to D farinae in the patient group. It is suggested that AD is associated with CMH reactions to allergens and that antigen competition may be involved in the reduced CMH responses to mitogens and antigens noted by other investigators.

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.

Allergies & Environmental Factors

Environmental factors are strongly associated with the prevalence of allergies and are an increasing health concern worldwide. Discover the latest research on Allergies and Environmental Factors here.
