Fig 2. VD3 deficiency alone worsens airway function and injury similar to Af-CRS.

(A) Penh and (B) sRaw were measured by dual-chamber whole-body restrained plethysmography 24 hours after the last Af i.n. instillation. (C) Nasal lavage total protein was measured as an indicator of upper airway damage. *p<0.01 vs control. # p<0.05 vs Af-CRS. n = 5–6 mice/group.
