Progress on the mechanism of alveolar macrophages in children with respiratory tract virus infection
Virus is one of the common causes of respiratory tract infection in children.Viral infection involves the action of multiple immune cells and inflammatory mediators,understanding the immune mechanism of virus-host interaction during respiratory infection may be helpful for etiological diagnosis of viral infections.As the main immune cells of the lungs,alveolar macrophages on the mucosal surface of the respiratory tract play an important role in maintaining pulmonary immune homeostasis(immune monitoring,initiation and regulation of inflammatory response,killing pathogens)due to their unique position.This article will briefly review the immune regulation mechanism of alveolar macrophages in the occurrence and development of respiratory tract viral infection in children,in order to provide reference for the prevention and treatment of viral infection.
