Co-stimulatory molecules of CD28, cytotoxic T lymphocyte-associated antigen-4 (CTLA-4), and the newly identified inducible co-stimulator (ICOS) are expressed on cell surfaces and provide regulatory signals for T-cell activation. Their genes are candidate susceptibility genes for type 1 diabetes because they co-localize to Chromosome 2q33 with the IDDM12(More)
Atopic asthma occurs in genetically susceptible individuals in the presence of environmental factors. Recently, the costimulation signal from CD80-CD86 to CD28/CTLA-4 has been suggested to play an important role in the development of atopic asthma. In the present study, we analyzed three polymorphic regions within the CTLA-4 gene, an A/G substitution in(More)
BACKGROUND Although the exact pathogenesis of subacute sclerosing panencephalitis (SSPE) remains to be determined, both viral and host factors seem to be involved. OBJECTIVE To identify host genetic factors involved in the development of SSPE. METHODS We investigated the association of polymorphisms in the T helper (Th)1 and Th2 cytokine, and related(More)
BACKGROUND IFN-gamma and related molecules play important roles in the differentiation and function of TH2 cells. OBJECTIVE We sought to determine whether IFNG and related genes contribute to any susceptibility to atopic asthma, a representative TH2-dominant disorder. METHODS We investigated the association of IFNG (CA repeat polymorphism within the(More)
Measles virus (MV) binding sites of the CD46 gene were sequenced in patients with subacute sclerosing panencephalitis (SSPE) and in controls. There were 3 novel polymorphisms, including C/T at nucleotide position 38 (C/T38), G/A at position 176 (G/A176), and C/T at position 453 (C/T453), at allele frequencies of.97:.03, .99:.01, and.97:.03, respectively.(More)
Tumour necrosis factor receptor-associated periodic syndrome (TRAPS) is a dominantly inherited disorder characterised by recurrent episodes of sustained fever. Here we report a case of TRAPS with a novel TNFRSF1A mutation, C70S, in a Japanese family. The mutation disrupts one of the three disulphide bonds in cysteine-rich domain 2 of TNF receptor 1, similar(More)
PURPOSE A patient with aggressive chronic active Epstein-Barr virus (CAEBV) infection is described whose disease activity subsided after interferon (IFN)-alpha therapy. PATIENT AND METHODS The patient had intermittent fever, cytopenia, liver dysfunction, hepatosplenomegaly, abnormal titers of EBV-associated antibodies, and positive EBV genomes. RESULTS(More)
Interleukin (IL)-4 and IL-13 play key roles in the development of atopic asthma. The IL-13 receptor (R) alpha' chain is a component of both IL-4R and IL-13R complexes. By screening the whole coding region of the IL-13Ralpha' gene for polymorphisms, we identified a new polymorphism at nucleotide position 1050 from the ATG start codon. The allelic frequency(More)
An 8 year old boy with ring chromosome 21 who was susceptible to sinorespiratory infections due to hypogammaglobulinaemia is reported. He presented with the characteristic features of monosomy 21 syndrome, such as psychomotor retardation, hypertonia, large saccular ears, prominent nasal bridge, micrognathia, thrombocytopenia, and patent ductus arteriosus.(More)
Pyogenic splenic abscess is a rare intraperitoneal infection caused by a variety of bacteria, with S. aureus and streptococci most commonly isolated. Splenectomy is indicated when it is resistant to antimicrobial therapy. We report on a pyogenic splenic abscess requiring repeated aspiration in an infant who was serologically diagnosed as having cat scratch(More)
