T144 0-184 Sentence denotes Several Gram-negative pathogens including members of the genera Neisseria and Moraxella have evolved two-component systems that can extract iron from the host LF and transferrin (157).
T145 185-258 Sentence denotes N. meningitidis is a principal cause of bacterial meningitis in children.
T146 259-505 Sentence denotes While the majority of pathogenic bacteria employ siderophores to chelate and scavenge iron (158), Neisseria has evolved a series of protein transporters that directly hijack iron sequestered in host transferrin, lactoferrin, and hemoglobin (159).
T147 506-808 Sentence denotes The system consists of a membrane-bound transporter that extracts and transports iron across the outer membrane (TbpA for transferrin and LbpA for lactoferrin), and a lipoprotein that delivers iron-loaded lactoferrin/transferrin to the transporter (TbpB for transferrin and LbpB for lactoferrin) (157).
T148 809-898 Sentence denotes LbpB binds the N-lobe of lactoferrin, whereas TbpB binds the C-lobe of transferrin (157).
T149 899-1111 Sentence denotes However, more than 90% of LF in human milk is in the form of apolactoferrin (160), which competes with siderophilic bacteria for ferric iron, and disrupts the proliferation of these microbial and other pathogens.
T150 1112-1198 Sentence denotes Similarly LF supplements may play an important role to counteract bacterial processes.
T151 1199-1315 Sentence denotes LF is consequently a significant element of host defense (19), and its levels may vary in health and during disease.
T152 1316-1398 Sentence denotes It is hence known to be a modulator of innate and adaptive immune responses (161).
