Abstract

Close
- Laminin is a well-defined component of the airway basement membrane (BM). Efficient binding of laminin via multiple interactions is important for nontypeable Haemophilusinfluenzae (NTHi) colonization in the airway mucosa. Here we identified elongation factor thermo-unstable (EF-Tu), L-lactate dehydrogenase (LDH), Protein D and peptidoglycan-associated lipoprotein P6 as novel laminin-binding proteins (Lbps) of NTHi. In parallel with other well-studied Lbps (P4, PE, PF and Hap), EF-Tu, LDH, PD and P6 exhibited interactions with laminin, and mediated NTHi laminin-dependent adherence to pulmonary epithelial cell lines. Importantly, the NTHi laminin interactome consisting of the well-studied and novel Lbps recognized laminin LG domains from the subunit α chains of laminin-111 and -332, of which the latter isoform is the main laminin in the airway BM. The NTHi interactome mainly targeted multiple heparin-binding domains of laminin. In conclusion, the NTHi interactome exhibited a high plasticity of interactions with different laminin isoforms via multiple heparin-binding sites.
