PURPOSE OF REVIEW The identification of regulatory T cells (Tregs) as regulators of immunological self-tolerance has stimulated tremendous interest in the field. Over the past 12 months, new studies have added greatly to our understanding of the role of Tregs in autoimmune disease, details of which are presented here. RECENT FINDINGS In this review, the(More)
Regulatory T cells (Tregs) are a subset of T cells which are involved in peripheral immune tolerance. Their role in autoimmune disease which occurs through a breakdown of tolerance is of particular interest in trying to ascertain the mechanism(s) of disease progression. It is hoped that by understanding the role of Tregs in autoimmunity a reliable therapy(More)
The identification of causal genes from genome-wide association studies (GWAS) is the next important step for the translation of genetic findings into biologically meaningful mechanisms of disease and potential therapeutic targets. Using novel chromatin interaction detection techniques and allele specific assays in T and B cell lines, we provide compelling(More)
Promising immunotherapeutic tools for T cell-mediated pathologies are alternatively activated dendritic cells (aaDC), which exert their effect through the regulation and tolerization of T cells. As naïve and memory T cells have different susceptibilities to tolerogenic signals, it is important to understand the modulatory effects of aaDC on these T cell(More)
OBJECTIVES Tolerogenic dendritic cells (tolDCs) constitute a promising experimental treatment for targeting autoreactive T cells in autoimmune diseases, including rheumatoid arthritis (RA). The authors' goal is to bring tolDC therapy for RA to the clinic. Here the authors address key translational issues related to the manufacturing of tolDCs from RA(More)
OBJECTIVES A previously identified signal transduction and activator of transcription-3 (STAT3) target-enriched gene signature in circulating CD4+ T cells of patients with early rheumatoid arthritis (RA) was prominent in autoantibody-negative individuals. Here, interleukin (IL)-6-mediated STAT signalling was investigated in circulating lymphocytes of an(More)
We show that the strength of T-cell stimulation determines the capability of human CD4(+) T cells to become interleukin-17 (IL-17) producers. CD4(+) T cells received either high- (THi) or low (TLo)-strength stimulation via anti-CD3/CD28 beads or dendritic cells pulsed with superantigen in the presence of pro-Th17 cytokines IL-1β, transforming growth factor(More)
Interleukin (IL)-17 is pivotal in orchestrating the activity of neutrophils. Neutrophilic inflammation is the dominant pathology in cystic fibrosis (CF) lung disease. We investigated IL-17 protein expression in the lower airway in CF, its cellular immunolocalisation and the effects of IL-17 on CF primary bronchial epithelial cells. Immunohistochemistry was(More)
Autoimmune pathologies are caused by a breakdown in self-tolerance. Tolerogenic dendritic cells (tolDC) are a promising immunotherapeutic tool for restoring self-tolerance in an antigen-specific manner. Studies about tolDC have focused largely on generating stable maturation-resistant DC, but few have fully addressed questions about the antigen-presenting(More)
Selected characteristics of the social environment are tested as predictors of children's risk for obesity. Data were collected during the summer of 1991 at the University of South Alabama Springhill Paediatric Clinic (Mobile, AL, USA). Data were collected on 77 children, aged 2.5-5 years, and their primary caretaker. Obesity risk was measured by the(More)
