Kimura, J, Takada, H, Nomura, A, Ohno, T, Mizuno, Y, Saito, M, ...

To clarify the functional state of T cells in Kawasaki disease, we analysed mRNA expression levels of Th1/Th2 cytokines (IFN-γ and IL-4) along with Th1/Th2-inducing transcription factors, T-bet and...

Microarray analysis of human milk cells: persistent high expression of osteopontin during the lactation period

NAGATOMO, T, OHGA, S, TAKADA, H, NOMURA, A, HIKINO, S, IMURA, M, ...

To continue the search for immunological roles of breast milk, cDNA microarray analysis on cytokines and growth factors was performed for human milk cells. Among the 240 cytokine-related genes,...

Distinct gene expression patterns of peripheral blood cells in hyper–IgE syndrome

Tanaka, T, Takada, H, Nomura, A, Ohga, S, Shibata, R, Hara, T

Hyper-immunoglobulin E (IgE) syndrome (HIES) is one of the primary immunodeficiency syndromes. Although the cytokine dysregulation is suggested to play a role in its pathophysiology, the causative...

Novel roles of osteopontin and CXC chemokine ligand 7 in the defence against mycobacterial infection

Khajoee, V, Saito, M, Takada, H, Nomura, A, Kusuhara, K, Yoshida, S-I, ...

Granulocyte-macrophage colony-stimulating factor (GM-CSF)-induced human monocyte-derived macrophage (GM-Mφ) or macrophage CSF (M-CSF)-induced human monocyte-derived Mφ (M-Mφ) are distinct in terms...

Maturational alterations of peripheral T cell subsets and cytokine gene expression in 22q11.2 deletion syndrome

Kanaya, Y, Ohga, S, Ikeda, K, Furuno, K, Ohno, T, Takada, H, ...

Chromosome 22q11.2 deletion syndrome is a common disorder characterized by thymic hypoplasia, conotruncal cardiac defect and hypoparathyroidism. Patients have a risk of infections and autoimmunity...

"Pseudo" hypertrophic neuropathy of childhood.

Baba, M, Takada, H, Miura, H, Okushima, T, Matsunaga, M

A 9 year old boy had chronic progressive motor-sensory neuropathy that started in early infancy. He had enlarged nerves and pes cavus deformity. Motor conduction studies showed very dispersed,...

Identification of novel MUNC13-4 mutations in familial haemophagocytic lymphohistiocytosis and functional analysis of MUNC13-4-deficient cytotoxic T lymphocytes

Yamamoto, K, Ishii, E, Sako, M, Ohga, S, Furuno, K, Suzuki, N, ...

Background: Familial haemophagocytic lymphohistiocytosis (FHL) has an autosomal recessive mode of inheritance and consists of at least three subtypes. FHL2 subtype with perforin (PRF1) mutation...

Acute cerebellar ataxia with human parvovirus B19 infection

Shimizu, Y., Ueno, T., Komatsu, H., Takada, H., Nunoue, T.

A 2 year old boy developed acute cerebellar ataxia in association with erythema infectiosum. During the disease, genomic DNA and antibodies against human parvovirus B19 were detected in serum but not...

Lipopolysaccharide-dependent down-regulation of CD27 expression on T cells activated with superantigen

Kai, K, Rikiishi, H, Sugawara, S, Takahashi, M, Takada, H, Kumagai, K

To investigate the mechanisms underlying T-cell responses during superantigen (SAg) stimulation, we analysed the effects of SAg on CD27 expression with or without lipopolysaccharide (LPS) as a novel...
