Members of the human ABC transporter A subfamily have gained considerable attention based on the recent findings that ABCA1 and ABCR (ABCA4) cause familial HDL-deficiency syndromes and distinct forms of hereditary retinopathies, respectively. Here we report the complete cDNA and the genomic organization of ABCA2, another member of the human ABC A(More)
AIM To assess the outcome of patients, who underwent transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) and subsequently liver transplantation (OLT) irrespective of tumor size when no tumor progression was observed. METHODS Records, imaging studies and pathology of 84 patients with HCC were reviewed. Ten patients were not treated at(More)
Neutrophils are thought to rely solely on nonspecific immune mechanisms. Here we provide molecular biological, immunological, ultrastructural, and functional evidence for the presence of a T cell receptor (TCR)-based variable immunoreceptor in a 5-8% subpopulation of human neutrophils. We demonstrate that these peripheral blood neutrophils express variable(More)
BACKGROUND Primary graft dysfunction due to ischemia and reperfusion injury represents a major problem in liver transplantation. The related cell stress may induce apoptosis, which can be suppressed by bcl-2. The purpose of the study was to investigate the effect of adenoviral bcl-2 gene transfer on early graft function and survival in rat liver(More)
BACKGROUND T-cell tolerance of allergic cutaneous contact sensitivity (CS) induced in mice by high doses of reactive hapten is mediated by suppressor cells that release antigen-specific suppressive nanovesicles. OBJECTIVE We sought to determine the mechanism or mechanisms of immune suppression mediated by the nanovesicles. METHODS T-cell tolerance was(More)
AIM To evaluate survival in patients undergoing palliative resection versus non-resection surgery for primary colorectal cancer in a retrospective analysis. METHODS Demographics, TNM status, operating details and survival were reviewed for 67 patients undergoing surgery for incurable colorectal cancer. Palliative resection of the primary tumor was(More)
Inhibition or destruction of Kupffer cells (KC) may protect against ischemia-reperfusion (IR) induced primary graft nonfunction (PNF) in liver transplantation. Besides KC activation, PNF is characterized by microvascular perfusion failure, intrahepatic leukocyte accumulation, cell death and hepatocellular dysfunction. KCs can be inactivated by different(More)
Macrophages play a central role in host defense against mycobacterial infection and anti- TNF therapy is associated with granuloma disorganization and reactivation of tuberculosis in humans. Here, we provide evidence for the presence of a T cell receptor (TCR) αβ based recombinatorial immune receptor in subpopulations of human and mouse monocytes and(More)
To study the prevalence and prognostic importance of mutations in NADH dehydrogenase subunit 4 (ND4), a mitochondrial encoded transmembrane component of the electron transport chain respiratory Complex I, 452 AML patients were examined for ND4 mutations by direct sequencing. The prognostic impact of ND4 mutations was evaluated in the context of other(More)
Recent evidence indicates constitutive expression of a recombinatorial TCRαβ immune receptor in mammalian monocytes and macrophages. Here, we demonstrate in vitro that macrophage-TCRβ repertoires are modulated by atherogenic low density cholesterol (LDL) and high-density cholesterol (HDL). In vivo, analysis of freshly obtained artery specimens from patients(More)
