Moreover, recent studies revealed FPR-1 played a critical role in regulating lung inflammation and injuries in bronchopulmonary dysplasia and it also has been demonstrated that FPR-1 can reduce lung injury by mediating neutrophil recruitment in endotoxin-induced ALI (Grommes et al., 2014; Kim et al., 2018). Here, FPR1 is linked to bronchopulmonary dysplasia.
