We have isolated a virus, which causes a mortal disease in cultured ornamental Koi and Common carps (Cyprinus carpio) in many countries worldwide. This unclassified virus, which causes nephritis and gill necrosis, and so has been given the name carp nephritis and gill necrosis virus (CNGV), has a morphology resembling the herpes virus, but bears a genomic(More)
Amyloid beta protein (Abeta) levels are elevated in the brain of Alzheimer's disease patients. Anti-Abeta antibodies can reverse the histologic and cognitive impairments in mice which overexpress Abeta. Passive immunization appears safer than vaccination and treatment of patients will likely require human rather than xenogenic antibodies. Effective(More)
Epstein-Barr virus (EBV) transforms human peripheral B cells into lymphoblastoid cell lines (LCLs), allowing the production of specific antibody-secreting cell lines. We and others have previously found that in contrast to peripheral blood B cells, EBV-transformed lymphoblastoid cell lines express the activation-induced cytidine deaminase (AID) gene. The(More)
Surface IgA-positive human lymphocytes were selected, separated, and immortalized with Epstein-Barr virus (EBV). Selection was carried out by rosetting the cells with ox erythrocytes, coated with rabbit anti-human IgA immunoglobulin, followed by separation on Ficoll-Isopaque. Stable monoclonal lines were established by cloning in agarose. This shows that(More)
CyHV-3 (Cyprinid herpesvirus-3) is a large DNA virus that causes a fatal disease in koi and common carp. Infection with wild type or attenuated virus induces an immune response that renders the fish resistant to further virus challenges. The kinetics and affinity of the antibody response in immune fish depend on the temperature of the water.(More)
While the presence of naturally occurring antibodies (Abs) against amyloid-beta in AD patients and healthy subjects have been repeatedly reported, no data on the presence of naturally occurring Abs against tau protein, in its unphosphorylated as well as its pathologically phosphorylated state, has been reported so far. We describe here the detection of(More)
Rheumatoid factors are the characteristic autoantibodies of rheumatoid arthritis, which bind to the Fc regions of IgG molecules. Here we report the crystal structure of the Fab fragment of a patient-derived IgM rheumatoid factor (RF-AN) complexed with human IgG4 Fc, at 3.2 A resolution. This is the first structure of an autoantibody-autoantigen complex. The(More)
A lethal disease of koi and common carp (species Cyprinus carpio) has afflicted many fish farms worldwide since 1998, causing severe financial losses. Morbidity and mortality are restricted to common carp and koi and appear in spring and autumn, when water temperatures are 18 to 28 degrees C. We have isolated the virus causing the disease from sick fish,(More)
Increasing antibiotic resistance and a rising patient population at risk for infection due to impaired immunity underscore the importance of vaccination against pneumococci. However, available capsular polysaccharide vaccines are often poorly immunogenic in patients at risk for pneumococcal disease. The goal of this study was to explore the potential of(More)
The tumour-associated antigen (TAA) GA733-2 is overexpressed by >90% of human colorectal carcinomas (CRC). The antigen has previously been shown to be recognised by B and T cells. The aim of the present study was to define B cell epitopes of GA733-2. Fifteen percent of CRC patients with no previous immunotherapy have recently been shown to elicit an(More)
