  1. 1. Colonic mucus structure and processing

    Författare :Elisabeth E. L. Nyström; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucus; CLCA1; Goblet cell; Spdef;

    Sammanfattning : The mucus layer covering the colonic epithelium creates a crucial first line of defense against the gut residing bacteria. Several lines of evidence suggest that a functional mucus layer is essential for health. For example, it is. suggested that ulcerative colitis is correlated with mucus layer defects. LÄS MER

  2. 2. Mucus and mucins during gastrointestinal infections

    Författare :Nazanin Navabi; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :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

  3. 3. The MUC2 mucin -A network in the intestinal protective mucus

    Författare :Malin E V Johansson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :mucus; Muc2; trimer; proteomics; intestine; colitis; DSS;

    Sammanfattning : The intestine is covered by mucus that is the first line of defence of the epithelium. The main structural component of the intestinal mucus is the MUC2 mucin. This is a large glycoprotein with two long and heavily O-glycosylated mucin domains. LÄS MER

  4. 4. Gastrointestinal mucosal protective mechanisms : Mudolatory effects of Heliobacter pyroli on the gastric mucus gel barrier and mucosal blood flow in vivo

    Författare :Christer Atuma; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; mucus gel layer; mucosal blood flow; mucus thickness; chronic infection; rat; platelet activating factor; mast cell; nitric oxide; nitric oxide synthase; ketotifen; intra-vital microscopy; microelectrode; laser-Doppler flowmetry; L- NNA; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : The gastrointestinal mucus gel layer and blood flow are two important mechanisms for protection at the pre-epithelial and sub-epithelial levels, respectively. Helicobacter pylori might circumvent these mechanisms and elicit a chronic inflammatory response with consequent ulcers in the stomach and duodenum. LÄS MER

  5. 5. Mucus associated proteins and their functional role in the distal intestine

    Författare :Joakim H. Bergström; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intestine; mucus; bacteria; MUC2; AGR2; FCGBP; ZG16;

    Sammanfattning : The mammalian intestine, especially the large intestine, harbors complex societies of beneficial bacteria coexisting with the host. This is a mutualistic relationship, where the host provides nutrients and a favorable environment while the bacteria in return ferment indigestible polysaccharides to short chain fatty acids. LÄS MER
