    Abstract : The intestine, with its large mucosal surface area, digests and absorbs food nutrients and maintains a beneficial microbial flora in the colon. Local protective immune responses against intestinal pathogens ensure the survival of the individual. These immune reactions are both specific and non-specific in nature. READ MORE

    Abstract : Cancer development depends on cells aquiring a skillset of limitless growth and finally invasive properties to allow for metastasis, as summarised by the six hallmarks of cancer. Recently four more hallmarks have been added: genomic instability, deregulating cellular metabolism, tumour-promoting inflammation and avoiding immune destruction. READ MORE

  5. 3. Biliary epithelial cells, the immune system and PSC pathogenesis

    Author : Lena Berglin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Primary sclerosing cholangitis (PSC) is a chronic, inflammatory liver disease that leads to destruction of the bile duct system.
