Abstract:
Respiratory viral infections are an important public health problem worldwide, with complex mechanisms of infection, and the key to infection lies in the specific binding between respiratory viruses and receptors. This article provides an overview of the progress in the study of receptors for respiratory viruses, such as coronavirus and influenza virus (IV), with a focus on the binding sites of receptors such as angiotensin-converting enzyme 2 (ACE2) and sialic acid (SA) to respiratory viruses and the role of receptor diversity in respiratory viral infections. An in-depth study of the binding sites between viruses and receptors will help to understand the molecular mechanism of respiratory viral infections and provide a theoretical basis for disease prevention and control and the development of new therapeutic targets.
