Abstract

Gamma-interferon (IFN-gamma) has immunosuppressive and immunostimulatory effects. Net results in clinical disease are difficult to predict. We studied possible anti-allergic effects of IFN-gamma in a double blind study in 30 patients with bronchial asthma. We performed quantitative skin prick and bronchial allergen provocation tests using each patient's main allergen prior to and after 20 injections of either recombinant IFN-gamma (100 micrograms each) or placebo, measuring skin wheal area, specific airway resistance (SRaw) and the maximal expiratory flow at 50% of vital capacity (MEF50). IFN-gamma reduced skin wheal area significantly but had no effect on allergic bronchoconstriction.

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.

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.
