It is known that NB-UVB therapy can suppress a broad range of immune cells, but the additional effect of bathing in geothermal seawater still remains unclear. To study the influence of treatment on the expression of circulating immune cells contributing to the pathogenesis of psoriasis, six patients with psoriasis were treated with bathing in geothermal seawater two times daily combined with NB...

OBJECTIVE AS is a systemic inflammatory disease of the SpA family. Polymorphisms at loci including HLA-B27, IL-23R and ERAP-1 directly implicate immune mechanisms in AS pathogenesis. Previously, in an SpA model, we identified HLA-B27-mediated effects on dendritic cells that promoted disease-associated Th17 cells. Here we extend these studies to AS patients using deep immunophenotyping of candid...

The factors that promote the differentiation of pathogenic T cells in autoimmune diseases are poorly defined. Use of genetically modified mice has provided insight into molecules necessary for the development of autoimmunity, but the sum of the data has led to contradictory observations based on what is currently known about specific molecules in specific signaling pathways. To define the minim...

Innate lymphoid cells (ILCs) contribute to host defence and tissue repair but can induce immunopathology. Recent work has revealed tissue-specific roles for ILCs; however, the question of how a small population has large effects on immune homeostasis remains unclear. We identify two mechanisms that ILC3s utilise to exert their effects within intestinal tissue. ILC-driven colitis depends on prod...

PURPOSE OF REVIEW To determine the advances made in the genetics of scleroderma in candidate gene association studies. RECENT FINDINGS Over the past 18 months, a number of candidate gene studies using large case-control series in scleroderma have been reported. The studies have identified multiple genes involved in immune regulation including BANK1, C8orf13-BLK, IL-23R, IRF5, STAT4, TBX21, an...

OBJECTIVES To explore the source of the p19 subunit of interleukin-23 (IL-23) in joints with rheumatoid arthritis (RA), the effects of IL-1beta and tumour necrosis factor (TNF)-alpha on IL-23 gene expression in RA fibroblast-like synoviocytes and the effect of IL-23 on proinflammatory cytokines. METHODS Expression of IL-23 p19 in joints was examined by immunohistochemical analysis of patients...

AIMS Retinoic acid receptor-related orphan nuclear receptor γt (RORγt) is a transcriptional factor responsible for IL-17-producing T-cell differentiation. Although it was demonstrated that RORγt plays essential roles in the onset of autoimmune myocarditis, pathophysiological significance of RORγt in cardiac remodeling after myocardial infarction (MI) remains to be fully elucidated. METHODS AN...
