Basophil histamine release by nuclear components in chronic bronchitis and bronchial asthma of intrinsic type

Abstract

The involvement of an allergic reaction directed against nuclear components and aggregated IgG was examined by basophil histamine release technique in chronic bronchitis (CB) in the intrinsic type of bronchial asthma (IA). In the group of 21 CB patients, seven responded to RNA, DNA or histone and three responded to aggregated IgG. In the other group of seven IA patients one responded to RNA and histone. In comparison with healthy blood donors the prevalence of smooth muscle antibodies was increased in CB patients and antinuclear antibodies were increased in both groups of patients. The findings suggest an involvement of an allergic reaction directed against RNA, DNA, histone, and aggregated IgG in some patients with CB and IA. This may play some role in the reversible airway obstruction of these diseases.

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.

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.

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.

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.
