  • Cellular and molecular mediators of intestinal fibrosis 

    Lawrance, Ian; Rogler, Gerhard; Bamias, Giorgos; Breynaert, Chrstine; Florholmen, Jon; Pellino, Gianluca; Reif, Shimon; Speca, Silvia; Latella, Giovanni (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-02)
    Intestinal fibrosis is a major complication of the inflammatory bowel diseases (IBD) and although inflammation is necessary for its development, it would appear that it plays a minor role in its progression as anti-inflammatory treatments in IBD do not prevent fibrosis once it has started. The processes that regulate fibrosis would thus appear to be distinct from those regulating inflammation and, ...
