INTRODUCTION Rheumatoid arthritis (RA) is a chronic progressive, inflammatory and destructive autoimmune disease, characterised by synovial joint inflammation and bone erosion. To better understand the pathophysiology and underlying immune mechanisms of RA various models of arthritis have been developed in different inbred strains of mice. Establishment of(More)
T-cells play an important role in controlling viral infections inside the CNS. To study the role of the chemokine receptor CXCR3 in the migration and positioning of virus-specific effector T-cells within the brain, CXCR3-deficient mice were infected intracerebrally with lymphocytic choriomeningitis virus (LCMV). Analysis of the induction phase of the(More)
BACKGROUND Recently we and others have identified CD8 and CD4 T cell epitopes within the highly expressed M. tuberculosis protein TB10.4. This has enabled, for the first time, a comparative study of the dynamics and function of CD4 and CD8 T cells specific for epitopes within the same protein in various stages of TB infection. METHODS AND FINDINGS We(More)
Generally, interferon-gamma (IFN-gamma) is considered a critical regulator of T cell mediated inflammation. For this reason, we investigated the pathogenesis of lymphocytic choriomeningitis in mice with a targeted defect of the gene encoding this cytokine. Our results revealed that IFN-gamma is redundant in the afferent phase of the antiviral T cell(More)
The human herpesvirus 8-encoded protein vMIP-II is a potent in vitro antagonist of many chemokine receptors believed to be associated with attraction of T cells with a type 1 cytokine profile. For the present report we have studied the in vivo potential of this viral chemokine antagonist to inhibit virus-induced T-cell-mediated inflammation. This was done(More)
The authors compared the subjective reaction of 13 panic patients and eight control subjects to a 35% CO2 challenge, a treatment known to produce physical symptoms comparable to those of natural or lactate-induced panic, and to placebo treatment (inhalation of air). They found that patients had higher placebo scores than control subjects, patients tended to(More)
BACKGROUND The aims of the present study were to determine the relationship between bone destruction and bone formation in the delayed-type hypersensitivity arthritis (DTHA) model and to evaluate the effect of receptor activator of nuclear factor κB ligand (RANKL) blockade on severity of arthritis, bone destruction, and bone formation. METHODS DTHA was(More)
Rodent models of arthritis have been extensively used in the elucidation of rheumatoid arthritis (RA) pathogenesis and are instrumental in the development of therapeutic strategies. Here we utilise delayed-type hypersensitivity arthritis (DTHA), a model in C57BL/6 mice affecting one paw with synchronised onset, 100% penetrance and low variation. We(More)
