AIM To study the involvement of the chemokine receptor CXCR3 and its ligands (CXCL9/Mig, CXCL10/IP-10, CXCL11/ITAC) in optic neuritis (ON). METHODS 30 patients with ON and 10 non-inflammatory neurological disease controls were included. The patients underwent a phlebotomy, lumbar puncture, and MRI scan. CXCR3 expression was studied on blood and cerebrospinal fluid (CSF) T cells by flow cytome...

BACKGROUND Human African trypanosomiasis or sleeping sickness, caused by the parasite Trypanosoma brucei, leads to neuroinflammation and characteristic sleep/wake alterations. The relationship between the onset of these alterations and the development of neuroinflammation is of high translational relevance, but remains unclear. This study investigates the expression of interferon (IFN)-γ and IF...

Coxsackievirus (CV)B3 is the primary cause of viral myocarditis. We previously observed CXC chemokine ligand 10 (CXCL10) upregulation in the myocardium early in infection. However, the impact of CXCL10 in CVB3-induced myocarditis is unknown. Using isolated primary mouse cardiomyocytes we demonstrated for the first time that cardiomyocytes can express CXCL10 on interferon-gamma stimulation. To e...

Chemokines are best recognized for their role within the innate immune system as chemotactic cytokines, signaling and recruiting host immune cells to sites of infection. Certain chemokines, such as CXCL10, have been found to play an additional role in innate immunity, mediating CXCR3-independent killing of a diverse array of pathogenic microorganisms. While this is still not clearly understood,...

INTRODUCTION The present study examines the levels of recently reported biomarkers, adenosine deaminase acting on RNA (ADAR), C-C motif chemokine ligand 2 (CCL2), C-X-C motif chemokine 10 (CXCL10), signal transducers and activators of transcription 1 (STAT1), and miR-146a in systemic lupus erythematosus (SLE) patients over multiple visits. METHODS Peripheral blood leukocytes were collected fr...

The role of chemokines in virus-induced acute hepatic failure is not well defined. In this study, we investigated the role of CXC chemokine receptor 3 (CXCR3) and its ligands chemokine Mig/CXCL9 (monokine induced by IFN-gamma) and IP-10/CXCL10 (interferon-gamma-inducible protein 10) in the recruitment of intrahepatic lymphocytes and subsequent acute hepatic failure. Balb/cJ mice (6 to 8 weeks, ...

In this study, we investigated the role of extracellular nucleotides in chemokine (KC, MIP-2, MCP-1, and CXCL10) expression and secretion by murine primary intestinal epithelial cells (IECs) with a focus on P2Y6 receptors. qRT-PCR experiments showed that P2Y6 was the dominant nucleotide receptor expressed in mouse IEC. In addition, the P2Y6 ligand UDP induced expression and secretion of CXCL10....

PURPOSE To observe the short-term dynamic change in serum CXC chemokine ligand-10 (CXCL10) levels in patients with Graves' disease (GD) before and after iodine therapy and to analyze the relationship between CXCL10 levels and clinical disease indices. METHODS ELISA was used to determine serum levels of CXCL10 in 43 patients with GD shortly before radioiodine therapy and on days six, 14, and 6...

Studies from a number of laboratories suggest that modulation of cytokine expression plays an integral role in the immunomodulatory activity of opioids. Previously, our laboratory reported that activation of the mu-opioid receptor induced the expression of CCL2, CCL5, and CXCL10, as well as CCR5 and CXCR4. Previous work has also suggested the possibility that TGF-beta may participate in the opi...
