IFITM1 and bronchopulmonary dysplasia: In addition, antimicrobial lactoferrin (LTF), neutrophilic myeloperoxidase (MPO), anti-streptococcus AGER and cathepsin D (CTSD), interferon alpha 1 (IFNA1), interferon induced transmembrane proteins (IFITM1, IFITM3), and the negative regulator of interferon response (NPIR) are likely to be important players in innate immune modulation of BPD pathogenesis.
