A distinct signature of interferon-stimulated genes linked to cross-protection against secondary viral infections in primary bronchial epithelial cells

Respiratory viral infections, such as those caused by rhinovirus, adenovirus, influenza, respiratory syncytial virus (RSV), and SARS-CoV-2, represent a major global health challenge. Despite extensive research, effective and specific antiviral treatments for these infections are still lacking, with patient care often limited to symptomatic relief. The SARS-CoV-2 pandemic, alongside the emergence of avian flu H1N1 and Nipah virus, has underscored the critical role of the respiratory tract as a critical viral target. Respiratory viral infections exhibit marked variability in infectivity and disease severity across different age groups. Epidemiological and cell-based evidence highlights distinc
