The present invention relates to a screening method for a therapeutic agent for pulmonary damage induced by the administration of high-concentration oxygen, and more specifically, to a screening method for a candidate material for a therapeutic agent for bronchopulmonary dysplasia (BPD) induced by the administration of high-concentration oxygen. The present inventors have discovered that FPR1 is over-expressed in lung tissues exposed to high-concentration oxygen, and as a result of focusing on the correlation between the expression of FPR1 and the development of BPD, have confirmed that BPD can be suppressed by inhibiting the expression or activity of FPR1. In view of this fact, a prophylactic or therapeutic material for BPD may be discovered in a rapid and accurate manner by checking whether the expression or activity level of FPR1 is inhibited, and thus, the screening method of the present invention may be beneficially used to effectively select and develop therapeutic agents for BPD.

Screening method for therapeutic substance for preventing or treating bronchopulmonary dysplasia (BPD)

A composition for alleviating, preventing, or treating hyperoxia-induced lung injury, the composition including the WKYMVm peptide as an active ingredient is described. The composition has an effect of increasing FPR2 activation and ERK phosphorylation, and also has an effect of improving alveolarization and angiogenesis in hyperoxia-induced lung injury models, and thus the composition is anticipated to be usefully used for the alleviation, prevention, or treatment of hyperoxia-induced lung injury, particularly bronchopulmonary dysplasia.
