Brief description Epithelial cell surface mucins are large complex proteins found on the surface of all mucosal epithelial tissues, for example in the respiratory, gastrointestinal, reproductive and urinary tracts. We have recently identified three of the seven genes currently known to produce this type of molecule. We propose that mucins have a very important role in maintaining the barrier between potentially infectious microorganisms often present in epithelial tracts and the internal organs. We also believe that these molecules trigger epithelial cell defensive responses to the presence of microorganisms. The proposed research aims to prove these propositions and to elucidate the molecular mechanisms underlying function of cell surface mucins. Understanding the function of cell surface mucins could lead to the development of new drugs to treat epithelial inflammation such as that seen in inflammatory bowel diseases and respiratory diseases such as asthma and cystic fibrosis.
