The biological activities of chemokine (C-C motif) ligand 2 (CCL2) are mediated via C-C receptor-2 (CCR2). Increased CCL2 level is associated with metastasis many cancers. In our study, we investigated the role CCL2/CCR2 axis in development spontaneous intestinal tumorigenesis using ApcMin/+ mouse model. Ablation CCR2 mice significantly increased overall survival and reduced tumor burden. Immun...

OBJECTIVE To evaluate serum levels of CXCL10 and CCL2 in a large series of PsA patients, and to relate chemokines levels to the clinical phenotype of these patients. METHODS Serum levels of CXCL10 and CCL2 were measured in 68 PsA patients, and in gender- and age-matched (1:1) controls drawn from the general population. RESULTS PsA patients showed significantly (p<0.001) higher mean CXCL10 s...

OBJECTIVE The role of inflammation in structural and symptomatic osteoarthritis (OA) remains unclear. One key mediator of inflammation is the chemokine CCL2, primarily responsible for attracting monocytes to sites of injury. We investigated the role of CCL2 and its receptor CCR2 in experimental OA. DESIGN OA was induced in 10 weeks old male wild type (WT), Ccl2-/- and Ccr2-/- mice, by destabi...

Expression of CCL2 (CC chemokine ligand 2) (or monocyte chemoattractant protein-1) regulates inflammatory cell infiltration in the liver and adipose tissue, favouring steatosis. However, its role in the pathogenesis of steatohepatitis is still uncertain. In the present study, we investigated the development of non-alcoholic steatohepatitis induced by an MCD diet (methionine/choline-deficient di...

Phosphorylation of G protein-coupled receptors and the subsequent recruitment of beta-arrestin play an important role in desensitization of receptor-mediated responses, including degranulation in leukocytes. In this study, we report that receptor phosphorylation also provides a stimulatory signal for CCR ligand 2 (CCL2) production. C3a stimulated degranulation in a basophilic leukemia RBL-2H3 c...

Emerging research has identified that neuroimmune factors are produced by cells of the central nervous system (CNS) and play critical roles as regulators of CNS function, directors of neurodevelopment and responders to pathological processes. A wide range of neuroimmune factors are produced by CNS cells, primarily the glial cells, but the role of specific neuroimmune factors and their glial cel...

Abstract Background Pain is reported as the leading cause of disability in common forms inflammatory arthritis conditions. Acting a key player nociceptive processing, neuroinflammation, and neuron-glia communication, chemokine CCL2/CCR2 axis holds great promise for controlling chronic painful arthritis. Here, we investigated how system dorsal root ganglion (DRG) contributes to peripheral pain s...

The therapeutic efficacy of anthracyclines relies, at least partially, on the induction of a dendritic cell- and T-lymphocyte-dependent anticancer immune response. Here, we show that anthracycline-based chemotherapy promotes the recruitment of functional CD11b(+)CD11c(+)Ly6C(high)Ly6G(-)MHCII(+) dendritic cell-like antigen-presenting cells (APC) into the tumor bed, but not into lymphoid organs....

CCL2 is a chemokine involved in brain inflammation, but the way in which it contributes to the entrance of lymphocytes in the parenchyma is unclear. Imaging of the cell type responsible for this task and details on how the process takes place in vivo remain elusive. Herein, we analyze the cell type that overexpresses CCL2 in multiple scenarios of T-cell infiltration in the brain and in three di...
