At the site of infection, there is a release of the chemical histamine from the mast cells and a constriction of the bronchioles in the airway tract causing difficulty in breathing. The immune system's cell-mediated response includes the activation of the B-cells and the T-cells as soon as an allergen or a foreign pathogen enters the immune system. After activation of the B cells and the T-cells, there is a secretion of cytokines by them causing the development of a hypersensitive immune response system. T cells consist of 2 classes of cells called cytotoxic T cells and helper T cells which become active to fight against foreign pathogens that may enter the body after breaching the defense mechanism of the body.
