Children have a higher chance of morbidity and mortality from respiratory viral infections. Severe respiratory viral infections like Respiratory Syncytial Virus (RSV) and Parainfluenza viruses can lead to the development of asthma in patients. Clinical researchers at Nationwide Children’s Hospital found that neuregulin-1 (Nrg-1) may be an effective and protective treatment for patients diagnosed with severe respiratory viral infections. Their successful models with mice showed that Nrg-1 may prevent post-viral airway disease and reduce mortality if further studied and applied to human patients in the future.
