Severe RSV infection during neonatal development significantly alters lung structure and the pulmonary immune micro-environment.

Neonatal RSV exposure results in long-term pulmonary inflammation and exacerbates allergic airways disease.

Neonatal RSV infection led to increased airway hyperreactivity in adult mice.
Inflammatory cytokines like TNF-α and IL-13 were elevated after neonatal RSV exposure.
Subepithelial fibrosis and chronic inflammation were observed in the lungs of infected mice.

If babies get a virus called RSV, it can make their lungs react badly to things like dust later when they grow up.

The study used a neonatal mouse model where mice were infected with RSV and later exposed to allergens to assess lung function and inflammation.

The study was conducted in a mouse model, which may not fully replicate human responses.

BALB/c mice, specifically seven-day-old pups.
