Dermatomyositis and polymyositis are disabling rheumatic diseases characterized by an appreciable number of T cells infiltrating muscle tissue. The precise phenotype, function and specificity of these cells remain elusive. In this study, we aimed to characterize T cells in muscle tissue and circulation and to investigate their association to clinical(More)
In this report, we investigated the effect of ODN containing immunostimulatory CG motifs as adjuvant with soluble antigen (SA) from Leishmania donovani. BALB/c mice were vaccinated with the soluble antigen with or without CpG-ODN as adjuvant and then challenged with L. donovani metacyclic promastigotes. CpG-ODN alone resulted in partial protection against(More)
OBJECTIVE Sporadic inclusion body myositis (IBM) is characterized by T cell infiltrates in muscle tissue, but their functional role is unclear. Systemic signs of inflammation are lacking, and the absence of beneficial effects following immunosuppression has challenged the notion of a role for the immune system. This study was undertaken to investigate the(More)
OBJECTIVE To investigate the involvement of the leukotriene B4 (LTB4) pathway in polymyositis (PM) and dermatomyositis (DM) and the effect of immunosuppressive treatment on the LTB4 pathway. METHODS 5-lipoxygenase (5-LO), 5-LO activating protein (FLAP) and LTB4 receptor-1 (BLT1) expression was analysed by immunohistochemistry in muscle tissue from(More)
BACKGROUND We have recently analyzed the profile of T-cell subtypes based on chemokine receptor expression in blood from untreated early rheumatoid arthritis (ueRA) patients compared to healthy controls (HC). Here, we compared the levels of the respective chemokines in blood plasma of ueRA patients with those of HC. We also studied the association of(More)
BACKGROUND T-cell infiltrates may persist in muscle tissue of polymyositis (PM) and dermatomyositis (DM) patients despite aggressive immunosuppressive treatment. Here, we investigated to what extent persistent T cells in affected muscle were FOXP3+, a marker for regulatory T cells (Tregs), or CD244+, a marker for CD28null T cells, and whether their presence(More)
The pathogenic role and frequency of T cell subtypes in early rheumatoid arthritis are still unclear. We therefore performed a comprehensive analysis of the circulating T cell subtype pattern in patients with untreated early rheumatoid arthritis compared to healthy control subjects. Peripheral blood mononuclear cells were obtained from 26 patients with(More)
OBJECTIVE Inflammatory T cell infiltrates in the skeletal muscle tissue of patients with polymyositis are dominated by CD28-negative effector (CD28(null) ) T cells of both the CD4 and CD8 lineage. These cells are potentially cytotoxic, and the aim of the present study was to develop a fully autologous cell culture system in which to investigate the(More)
