PPT-HYPERSENSITIVITY DEFINATION

Normally immune is protective leading to only subclinical or localized response Sometimes the response becomes exaggerated causing extensive tissue damage Defined as Injurious consequences in the sensitised host following subsequent contact with specific antigens. A different paradigm has evolved in which cough is viewed as the primary condition characterised by afferent neuronal hypersensitivity and different aspects of this syndrome are manifest in the different phenotypes of cough There are several advanta immunology.
