First-aid for defective mucus

In our mouths, stomachs and eyes, mucus forms a protective layer that prevents friction and keeps foreign bodies out. The main components of mucus are mucins, which bind water molecules. However, if these mucins are damaged, they can lose this ability. A team of researchers, headed by Professor Oliver Lieleg at the Technical University of Munich (TUM), has now found a way to repair defective mucins. Proper lubrication is crucial to keep not only machines but also humans functioning smoothly. The mucus membranes in our mouths, eyes, stomachs and genital area help keep friction to a minimum and also protect us against environmental hazards such as chemicals and pathogens. Professor Oliver Lieleg and his working group at the Institute of Medical Technology (IMETUM) at TUM are investigating exactly how these mechanisms work.
