Hyper-immunoglobulin E syndrome (HIES) is a compound primary immunodeficiency characterized by a highly elevated serum IgE, recurrent staphylococcal skin abscesses and cyst-forming pneumonia, with disproportionately milder inflammatory responses, referred to as cold abscesses, and skeletal abnormalities. Although some cases of familial HIES with autosomal(More)
Individuals with autism spectrum disorder (ASD) have severe difficulties in social interaction and communication, as well as restricted and/or stereotyped patterns of behavior. Previous studies have suggested that abnormal neural connectivity might be associated with higher information processing dysfunction involving social impairment. However, the white(More)
Febrile seizures (FSs) are the commonest form of convulsions. A genetic predisposition to FSs is known, based on family studies, twin studies, and complex segregation analysis. Simple FSs may be more homogenous in their clinical manifestations, and show better agreement with the multifactorial inheritance theory than the complex type. Interleukin-1 (IL-1)(More)
Hyper-IgE syndrome (HIES) is a primary immunodeficiency characterized by atopic manifestations and susceptibility to infections with extracellular pathogens, typically Staphylococcus aureus, which preferentially affect the skin and lung. Previous studies reported the defective differentiation of T helper 17 (Th17) cells in HIES patients caused by(More)
Hyper-IgE syndrome (HIES) is a primary immunodeficiency characterized by recurrent staphylococcal infections and atopic dermatitis associated with elevated serum IgE levels. Although defective differentiation of IL-17-producing CD4(+) T cells (Th17) partly accounts for the susceptibility to staphylococcal skin abscesses and pneumonia, the pathogenesis of(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)
Human interleukin (IL) 1 receptor-associated kinase 4 (IRAK-4) deficiency is a recently discovered primary immunodeficiency that impairs Toll/IL-1R immunity, except for the Toll-like receptor (TLR) 3- and TLR4-interferon (IFN)-alpha/beta pathways. The clinical and immunological phenotype remains largely unknown. We diagnosed up to 28 patients with IRAK-4(More)
Acute disseminated encephalomyelitis (ADEM) has recently been studied in several countries owing to the development and wide spread use of imaging technology, but few epidemiological studies of childhood ADEM have been undertaken in Asian countries. To perform a comprehensive survey of ADEM and related diseases in Japanese children, we conducted a(More)
OBJECTIVE A genetic predisposition to febrile seizures (FS) has long been recognized. The inheritance appears to be polygenic in small families or sporadic cases of FS encountered in daily clinical practice. To determine whether candidate genes are responsible for the susceptibility to FS, we have performed genetic association studies in FS patients and(More)
Cytokines have been shown to influence susceptibility to febrile seizures and epilepsy. In this study, the role of interleukin-1beta (IL-1beta) was examined in developing rats. IL-1beta and interleukin-1 receptor antagonist (IL-1ra) were administered to developing rats, and seizures were induced by moist warm air. Twenty male Lewis rats (21-23 days old)(More)
