  1. 6. Mucus and mucins during gastrointestinal infections

    Författare :Nazanin Navabi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mucin; gastrointestinal cell lines; mucus layer; secreted mucin; cell surface mucin; H. pylori; C. rodentium; ETEC; mucin secretion; goblet cells;

    Sammanfattning : The gastrointestinal tract is protected by a continuously secreted mucus layer formed by mucin glycoproteins. The mucus layer and mucins change dynamically during infection. The main focus of this thesis was to investigate the changes in mucin and the mucus layer in the gastrointestinal tract during infection with the gastrointestinal pathogens C. LÄS MER
