Among the nebulized IL‐37‐treated group mice, moderate interstitial pneumonitis was observed in three out of five cases, whereas mild interstitial pneumonitis occurred in two cases, indicating reduced lung inflammation and alleviation of inflammatory cell infiltration due to the inhibitory effect of nebulized IL‐37 administration on inflammation caused by BA.5 infection (Figure 4F). The gene discussed is IL37; the disease is Interstitial pneumonitis.
