OBJECTIVE To determine whether changes in serum KL-6 levels reflect the activity of pulmonary fibrosis (PF) in patients with systemic sclerosis (SSc). METHODS KL-6 levels were determined by ELISA in 39 SSc patients. In a retrospective longitudinal study, 250 serum samples were analyzed during a follow-up period of 0.3-6.1 years. RESULTS KL-6 levels at(More)
B cells mediate multiple functions that influence immune and inflammatory responses. In this study, T cell-mediated inflammation was exaggerated in CD19-deficient (Cd19(-/-)) mice and wild-type mice depleted of CD20(+) B cells, whereas inflammation was substantially reduced in mice with hyperactive B cells as a result of CD19 overexpression (hCD19Tg). These(More)
EAE is a mouse T cell-mediated autoimmune disease of the CNS used to model the human condition MS. The contributions of B cells to EAE initiation and progression are unclear. In this study, we have shown that EAE disease initiation and progression are differentially influenced by the depletion of B cells from mice with otherwise intact immune systems. CD20(More)
OBJECTIVE To determine whether serum interleukin 4 (IL-4), IL-10, and IL-13 levels in patients with systemic sclerosis (SSc) are elevated and whether they correlate with the clinical or serologic features of this disease. METHODS Serum samples from patients with limited cutaneous SSc (ISSc) (n = 45), diffuse cutaneous SSc (dSSc) (n = 28), and control(More)
OBJECTIVE To identify the 140-kd autoantigen recognized by anti-155/140 autoantibodies that are associated with adult cancer-associated dermatomyositis (DM) and juvenile DM and to determine the clinical relevance of anti-155/140 antibodies in a large cohort. METHODS Sera from 456 DM patients were assessed for the presence of anti-155/140 antibodies by(More)
OBJECTIVE To clarify the association of clinical and prognostic features with dermatomyositis (DM)-specific autoantibodies (Abs) in adult Japanese patients with DM. DESIGN Retrospective study. SETTING Kanazawa University Graduate School of Medical Science Department of Dermatology and collaborating medical centers. Patients A total of 376 consecutive(More)
OBJECTIVE To identify similarities and differences in the clinical features of adult Japanese patients with individual anti-aminoacyl-tRNA synthetase antibodies (anti-ARS Abs). METHODS This was a retrospective analysis of 166 adult Japanese patients with anti-ARS Abs detected by immunoprecipitation assays. These patients had visited Kanazawa University(More)
Endometrial stromal differentiation (decidualization) is essential for implantation of the developing blastocyst. To investigate the process of progesterone (P)-induced decidualization of human endometrial stromal cells (ESC), a complementary DNA library enriched with P-induced genes was constructed from cultured human ESC by subtractive hybridization and(More)
BACKGROUND Butyrate, a fermentation product of intestinal bacteria, modifies chromatin structure through histone acetylation, thereby altering gene transcription. IL-8 and MCP-1 are chemokines, expressed by intestinal epithelial cells, which attract neutrophils and monocytes, respectively. We hypothesized that butyrate may alter IL-8 and MCP-1 expression by(More)
Understanding the molecular mechanisms through which CD22 regulates B lymphocyte homeostasis, signal transduction, and tolerance is critical to defining normal B cell function and understanding the role of CD22 in autoimmunity. Therefore, CD22 function was examined in vivo and in vitro using B cells from CD22-deficient (CD22(-/-)) mice. Backcrossing of(More)
