The Laminin Interactome: A Multifactorial Laminin-Binding Strategy by Nontypeable Haemophilus influenzae for Effective Adherence and Colonization.

ABSTRACT: Laminin is a well-defined component of the airway basement membrane (BM). Efficient binding of laminin via multiple interactions is important for nontypeable Haemophilus influenzae (NTHi) colonization in the airway mucosa. In this study, we identified elongation factor thermo-unstable (EF-Tu), l-lactate dehydrogenase (LDH), protein D (PD), and peptidoglycan-associated lipoprotein P6 as novel laminin-binding proteins (Lbps) of NTHi. In parallel with other well-studied Lbps (protein 4 [P4], protein E [PE], protein F [PF], and Haemophilus adhesion and penetration protein [Hap]), EF-Tu, LDH, PD, and P6 exhibited interactions with laminin, and mediated NTHi laminin-dependent adherence to pulmonary epithelial cell lines. More importantly, the NTHi laminin interactome consisting of the well-studi
