Virus-Induced Airway Inflammation

Description

Virus-induced cytokine production and inflammatory cell activation are instrumental in the development of neurogenic inflammatory responses, and these combined factors increase bronchoconstriction in response to allergens or irritants. Viral infections can influence both the development and the severity of asthma. In early life, viral infections can either increase or, remarkably, decrease the risk of subsequent asthma. In children and adults with existing asthma, viral respiratory infections frequently cause acute airway obstruction and wheezing.

The airway epithelium is the first cellular component of the lung to be encountered by the particles and pathogens present in inhaled air. Hence it is the focal point in the pathogenesis of viral respiratory infections because it serves as the host cell for viral replication, and [...]
