Of note, Lf has been proven to act as a scavenger against iron overload and inflammation in lung epithelium of mice infected by Pseudomonas aeruginosa [64,65], and bLf was found to rebalance lung iron-handling proteins and to decrease broncho-alveolar iron overload, one of the main actor in infection progression and exacerbation [65]. Here, LTF is linked to infection.
