UNLABELLED Early detection of malignant biliary tract diseases, especially cholangiocarcinoma (CC) in patients with primary sclerosing cholangitis (PSC), is very difficult and often comes too late to give the patient a therapeutic benefit. We hypothesize that bile proteomic analysis distinguishes CC from nonmalignant lesions. We used capillary(More)
Nuclear migration depends on microtubules, the dynein motor complex, and regulatory components like LIS1 and NUDC. We sought to identify new binding partners of the fungal LIS1 homolog NUDF to clarify its function in dynein regulation. We therefore analyzed the association between NUDF and NUDC in Aspergillus nidulans. NUDF and NUDC directly interacted in(More)
Mast cells (MCs) that are well known for their important effector function in IgE-associated immune responses play a key role in innate immune defenses. In this study, we investigate the interaction between MCs and NK cells in vitro and in vivo. We show that mouse bone marrow-derived cultured MCs activated with LPS, polyinosinic-polycytidylic acid, or CpG(More)
BACKGROUND AND STUDY AIMS Immunoglobulin G4 (IgG4)-associated cholangitis (IAC) is difficult to diagnose because on cholangiography the associated biliary tract strictures cannot be differentiated from cholangiocarcinoma or primary sclerosing cholangitis (PSC). Serum IgG4 levels show a low sensitivity and specificity and are unreliable, particularly in(More)
Eosinophils have been implicated in the pathogenesis of inflammatory bowel disease (IBD). Immunohistopathological studies have revealed accumulation and activation of eosinophils in actively inflamed intestinal mucosa of Crohn's disease and ulcerative colitis patients. Elevated levels of chemokines relevant for eosinophil chemotaxis and mediator release(More)
