Worsening mucus production in mAlum offspring over course of secondary RSV exposure. At 8dpse, lungs were formalin-fixed, paraffin-embedded, and processed for PAS staining. Each panel represents an individual mouse from each offspring group (A, C). Lung sections were scored, and the proportion of airways scored as having no PAS staining (none), airways with 1-50% PAS staining (mild), and airways with 51-100% PAS staining (severe) was calculated (B, D). n=3 mice per group.
