Bronchopulmonary dysplasia impairs L-type amino acid transporter-1 expression in human and baboon lung.

Bronchopulmonary dysplasia (BPD) is an inflammatory lung disorder common in premature infants who undergo mechanical ventilation with supplemental oxygen. Inhaled nitric oxide (iNO) has been used to prevent experimental and clinical BPD. Earlier studies showed that NO effects in alveolar epithelial cells (AEC) are mediated by S-nitrosothiol uptake via L-type amino acid transporter-1 (LAT1).
