Phenotypic and functional properties of gammadelta T cells, which play an important role in mucocutaneous immunity, were examined to elucidate whether immunological abnormality in Behcet's disease may be related to a specific T cell population. We found that CD45RA+ Vgamma9+ Vdelta2+ gammadelta T cells, which constitute a minor population of gammadelta T(More)
The efficacy and safety of oral cyclosporin 10 mg/kg per day in Behçet's disease were compared in a randomised double-masked study with those of colchicine, 1 mg orally per day, and were also investigated in a long-term open study. The double-masked study showed that cyclosporin was effective in treating not only the ocular manifestations of Behçet's(More)
OBJECTIVE Behçet's disease (BD) with uveoretinitis is a chronic refractory disease accompanied by ocular attacks. As the decrease in visual acuity due to ocular attack is seriously life-threatening, development of a new drug is anticipated. Since tumor necrosis factor-a (TNF-a) is involved in the symptoms of BD, particularly the activity of ocular symptoms,(More)
Eighty-one Behcet's disease patients have been studied for HLA association by HLA-DRB1, -DQA1, -DQB1 and -DPB1 genotyping with the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique and for NcoI RFLP in the tumor-necrosis factor (TNF beta) gene by Southern hybridization in addition to serological typing. In serological(More)
The notion that autoimmune mechanisms play a role in the pathogenesis of certain uveitic conditions in humans is supported by the observation that lymphocytes from such patients respond in culture against retinal specific antigens which are uveitogenic in animals. A large proportion of uveitis patients with Behçet's disease are reported to respond well to S(More)
Behçet's disease is known to be associated with HLA-B51. To address the possibility that a non-human leukocyte antigen (HLA) gene closely linked to the HLA-B gene, such as tumor necrosis factor (TNF)-alpha, TNF-beta, or ECl (the locus that determines the susceptibility to alloreactive natural killer [NK] cells), is involved in the susceptibility to Behçet's(More)
BACKGROUND Behçet's disease (BD) is a recurrent inflammatory disease involving chronic recurrent oral aphthous ulcers (aphthae), uveitis, skin lesions and genital ulcers. We prospectively investigated the efficacy of rebamipide, a gastroprotective drug, against oral aphthous ulcers in BD patients. METHODS In a multicentre, double-blind, placebo-controlled(More)
