Role of Basophils in Human Allergic Disease
Abstract:
The role of mast cells and basophils in human allergic disease is suggested by several lines of evidence. These high-affinity IgE-receptor bearing cells have been implicated in asthma, allergic rhinitis, and atopic dermatitis. Experimental investigations of antigen-induced inflammation in vivo have revealed both immediate reactions and so-called late-phase reactions in all organs studied. It is our hypothesis that the immediate hypersensitivity reaction is driven by mast cells while the late-phase reaction, which occurs hours later, is driven, in part, by basophil mediators.

Allergic Reactions
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Allergic Drug Reactions
Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
