Mucosal-associated invariant T (MAIT) cells have been reported to play an antimicrobial role in infectious diseases. However, little is known about age- and gender-related changes in circulating MAIT cell level and function in healthy population. The purposes of this study were to examine the level and cytokine production of circulating MAIT cells and their(More)
OBJECTIVE This study was designed to examine the frequency of natural killer T (NKT) cells and the response to α-galactosylceramide (α-GalCer) in SLE patients and to investigate the clinical relevance of NKT cell levels. METHODS Patients with SLE (n = 128) and age- and sex-matched healthy controls (HCs) (n = 92) were enrolled in the study. NKT cell and(More)
OBJECTIVES To examine two single-nucleotide polymorphisms (SNPs) for their association with knee osteoarthritis (OA) susceptibility in Korean cohort. METHODS Two thousand four hundred and sixty-two subjects aged 50 years and older were assessed for OA at the knee, were genotyped with two SNPs (GDF5; rs143383 and ADAM12; rs3740199). Radiographs were read(More)
Mucosal-associated invariant T (MAIT) cells contribute to protection against certain microorganism infections and play an important role in mucosal immunity. However, the role of MAIT cells remains enigmatic in autoimmune diseases. In this study, we examined the level and function of MAIT cells in patients with rheumatic diseases. MAIT cell, cytokine, and(More)
Natural killer T (NKT) cells have been reported to play crucial roles in a variety of diseases, including infectious diseases, autoimmunity, and cancers. Previous studies have reported wide age- and/or sex-related variations in circulating NKT cell levels in healthy subjects, but reported results are discrepant. In this study, the authors examined NKT cell(More)
Natural killer T (NKT) cells are known to play a protective role in the immune responses of mice against a variety of infectious pathogens. However, little is known about the detailed information of NKT cells in patients with Mycobacterium tuberculosis infection. The aims of this study were to examine NKT cell levels and functions in patients with active M.(More)
INTRODUCTION The purpose of this study was to analyze the cellular expressions of pro-resorptive cytokines in gouty tophus tissues, to determine the capacity of monosodium urate monohydrate (MSU) crystals to induce these cytokines, and to understand the mechanisms of bone destruction in chronic gout. METHODS Fourteen fixed, paraffin-embedded, uninfected(More)
The aim of this study was to examine a single-nucleotide polymorphism (SNP) rs7639618 of double von Willebrand factor (DVWA) gene for the association with osteoarthritis (OA) susceptibility in Korean cohort. The study was a part of the Korean cohort study. Two thousand four hundred sixty-two subjects aged 50 years and older who were derived from the cohort(More)
OBJECTIVE To examine the levels and functions of natural killer (NK) and natural killer T (NKT) cells, investigate relationships between NK and NKT cells, and determine the clinical relevance of NKT cell levels in patients with adult-onset Still's disease (AOSD). METHODS Patients with active untreated AOSD (n = 20) and age- and sex-matched healthy(More)
Rheumatoid arthritis (RA) and antisynthetase syndrome (ASS) are distinct clinical syndromes, and their co-occurrence is rarely encountered. The authors report the case of a 56-year-old female patient with RA of 3 years duration who suddenly developed ASS, and include a review of the literature. The patient was diagnosed with ASS based on; positivity for(More)
