We read the excellent presentation by Rodriguez-Argente and coauthors and wish to add some thoughts to the discussion1 . The lactoperoxidase (LPO) system is actually the first line of mammalian, immunological defense against airborne bacterial and viral infections, including influenza and the respiratory syncytial virus (RSV)2,3 . This is not well known and some textbooks of immunology don't even mention this system.
