Role of aquaporins in upper airway humidification. (A, left) Representative time course of humidity (top), air flow (middle), and airway pressure (bottom) in a wild-type mouse. (right) Same study done on an AQP3/AQP4 double knockout mouse. (B) Averaged relative humidity (mean ± SEM, n = 5 mice) in wild-type mice, and AQP3/AQP4 and AQP1/AQP5 double knockout mice as a function of minute ventilation.
