PURPOSE Acute anterior uveitis (AAU) is the most common form of uveitis. Up to 50% of patients with AAU are HLA-B27 positive. Since HLA B27 itself plays only a minor role in the overall genetic background, other genetic variants are likely to contribute to the susceptibility to AAU. The chemokine (C-C motif) ligand 2 (CCL2) gene, coding for monocyte chemoattractant protein-1 (MCP-1), a chemotac...
OBJECTIVES A nonagonist monocyte chemotactic protein-1 (MCP-1/CCL2) mutant (PA508) with increased affinity for glycosaminoglycans and thus competing with CCL2 was evaluated as a candidate for preventing neointima formation or myocardial ischemia/reperfusion injury. BACKGROUND Myocardial infarction (MI) remains a major cause of death worldwide despite improved interventional and therapeutic op...
CCL2 (MCP-1, monocyte chemoattractant protein 1) and CCL3 (MIP-1alpha, macrophage inflammatory protein 1alpha) are required for macrophage infiltration in adipose tissue. Insulin increases CCL2 expression in adipose tissue and in serum more in insulin-resistant obese than in insulin-sensitive lean mice, but whether this is true in humans is unknown. We compared basal expression and insulin regu...
Monocytes, macrophages, dendritic cells and microglia play critical roles in the local immune response to acute and chronic tissue injury and have been implicated in the pathogenesis of age-related macular degeneration. Defects in Ccl2-Ccr2 and Cx3cl1-Cx3cr1 chemokine signalling cause enhanced accumulation of bloated subretinal microglia/macrophages in senescent mice and this phenomenon is repo...
976 INSIGHTS | The Journal of Experimental Medicine Macrophages are critically important for the regulation of tumor growth and metastases. They contribute to tumor angiogenesis, tumor cell extravasation, and survival at the sites of metastases. Now, Kitamura et al., using mouse models of breast cancer, have uncovered a major role for a CCL2-induced chemokine cascade that supports macrophage re...
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...
Background & Aims : Henoch–Schönlein purpura (HSP) is an autoinflammatory disease and systemic small vessel vasculitis that more frequently occurs in children. It is characterized by skin lesion such as Petechia and purpura, gasterointestinal involvement including abdominal pain and gastrointestinal bleeding and arthiritis. Studies have shown that HSP could be due to different infections an...
Muscle injury triggers inflammation in which infiltrating mononuclear phagocytes are crucial for tissue regeneration. The interaction of the CCL2/CCR2 and CX3CL1/CX3CR1 chemokine axis that guides phagocyte infiltration is incompletely understood. Here, we show that CX3CR1 deficiency promotes muscle repair and rescues Ccl2(-/-) mice from impaired muscle regeneration as a result of altered macrop...
Some studies have linked the presence of chemokines to the early stages of Alzheimer's disease (AD). Then, the identification of these mediators may contribute to diagnosis. Our objective was to evaluate the levels of beta-amyloid (BA), tau, phospho-tau (p-tau) and chemokines (CCL2, CXCL8 and CXCL10) in the cerebrospinal fluid (CSF) of patients with AD and healthy controls. The correlation of t...
Our studies focus on the pathways that restrict homing of specific subsets of immune cells, and thereby fine-tune the immune response at specific lymphoid and peripheral tissues. Here, we report that CCL2 (at picomolar [pM] levels) renders both murine and human T cells defective in their ability to develop CCR7-triggered activation of LFA-1- and LFA-1-mediated adhesion strengthening to endothel...
