Chemokines are instrumental in macrophage- and T cell-dependent diseases. The chemokine CCL2 promotes kidney disease in two models of immune-mediated nephritis (MRL-Fas(lpr) mice and the nephrotoxic serum nephritis model), but evidence suggests that multiple chemokines are involved. For identification of additional therapeutic targets for immune-mediated nephritis, chemokine ligands and recepto...

C-X-C motif chemokine ligand (CXCL) 9 and CXCL10 play key roles in the initiation and development of acute transplant rejection. Previously, higher levels of RANTES expression and secretion were demonstrated in retransplantation or T-cell memory-transfer models. In the present study, the effect of the chemokines, CXCL9 and CXCL10, were investigated in a mouse retransplantation model. BALB/c mic...

BACKGROUND AND PURPOSE The chemokine receptor CXCR3 directs migration of T-cells in response to the ligands CXCL9/Mig, CXCL10/IP-10 and CXCL11/I-TAC. Both ligands and receptors are implicated in the pathogenesis of inflammatory disorders, including atherosclerosis and rheumatoid arthritis. Here, we describe the molecular mechanism by which two synthetic small molecule agonists activate CXCR3. ...

BACKGROUND Alopecia Areata (AA) is a non-scarring, autoimmune disorder which causes hair loss. Inflammatory reactions are involved in hair loss of the scalp and/or body. The involvement of chemokine receptors in the pathogenesis of AA is well defined among which, CXCL1 acts on neutrophils and CXCL9, CXCL10 and CXCL12 serve as T lymphocytes recruiters. OBJECTIVE To study the serum levels of EL...

The accumulation of T cells in the synovial membrane is the crucial step in the pathophysiology of the inflammatory processes characterizing juvenile idiopathic arthritis (JIA). In this study, we evaluated the expression and the pathogenetic role in oligoarticular JIA of a CXC chemokine involved in the directional migration of activated T cells, i.e. IFNgamma-inducible protein 10 (CXCL10) and i...

Lung disease due to non-tuberculous mycobacteria (NTM) is a poorly understood condition that is difficult to treat. Treatment remains problematic as few tools are available to help clinicians monitor disease progression or predict treatment outcome. In this study, plasma levels of several inflammatory molecules and the frequency of circulating T cell subsets were measured in patients with NTM l...

BACKGROUND The goal of this study was to characterize urinary metabolomics for the noninvasive detection of cellular inflammation and to determine if adding urinary chemokine ligand 10 (CXCL10) improves the overall diagnostic discrimination. METHODS Urines (n = 137) were obtained before biopsy in 113 patients with no (n = 66), mild (borderline or subclinical; n = 58), or severe (clinical; n =...

In asthma, airway smooth muscle (ASM) CXCR3 ligand production may attract mast cells or T-lymphocytes to the ASM where they can modulate ASM functions. In ASM cells (ASMC) from people with or without asthma, we aimed to investigate JAK-STAT1, JNK and calcium involvement in CXCL10 and CXCL11 production stimulated by interferon-γ, interleukin-1β and tumour necrosis factor-α combined (cytomix). Co...

INTRODUCTION Our recent data showed that signal transducers and activators of transcription 1 (STAT1), adenosine deaminase acting on RNA (ADAR), C-C motif chemokine ligand 2 (CCL2), and C-X-C motif chemokine 10 (CXCL10) were significantly elevated in a systemic lupus erythematosus (SLE) cohort compared to healthy donors. High and low STAT1 subsets were identified in SLE patient visits. The pres...

BACKGROUND Visceral leishmaniasis (VL) caused by Leishmania infantum is characterised by the loss of the ability of the host to generate an effective immune response. Chemokines have a direct involvement in the pathogenesis of leishmaniasis, causing a rapid change in the expression of these molecules during infection by Leishmania. OBJECTIVES Herein, it was investigated the role of CXCL10 in ...
