Lipocalin-2 from both myeloid cells and the epithelium combats Klebsiella pneumoniae lung infection in mice

To the editor: Lipocalin-2 is a eukaryotic siderophore-binding protein that prevents the growth and spread of microorganisms that require siderophore-mediated uptake of soluble iron.[1][1] Consequently, lipocalin-2 knockout mice ( Lcn2 −/− mice) are more susceptible to infection with the
