Abstract

We tested the effects of disodium cromoglycate (DSCG) on antigen-induced IL-2 responsiveness in lymphocytes from patients with atopic dermatitis and/or bronchial asthma. Patient lymphocytes pretreated with 5 x 10(3) micrograms/ml DSCG for 24 or 48 hours failed to induce the responsiveness to IL-2 on stimulation with Dermatophagoides farinae (Df) or ovalbumin (OVA) antigen. DSCG-treated adherent cells were blocked to present the antigen to nonadherent responding cells for induction of IL-2 responsiveness. In contrast, DSCG-treated non-adherent cells, recombined with antigen-activated adherent cells, acquired IL-2 responsiveness. However, Con A-activated lymphocytes from the same patients were not affected by the same treatment. The results indicate that DSCG is capable of suppressing antigen-induced IL-2 responsiveness but not the response induced by mitogen such as Con A.

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.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
