MCP-1/CCL2 plays an important role in the initiation and progression of cancer. Since tumor cells produce MCP-1, they are considered to be the main source of this chemokine. Here, we examined whether MCP-1 produced by non-tumor cells affects the growth and lung metastasis of 4T1 breast cancer cells by transplanting them into the mammary pad of WT or MCP-1(-/-) mice. Primary tumors at the inject...

chemokines and their receptors  play an important  role in the  late inflammatory stage of asthma. in this study, we aimed to investigate polymorphisms of mcp-1 (ccl2), ccr2 and ccr5 which can affect qualitatively and/or quantitatively their production and thus influence both susceptibility and severity of asthma and its clinical and biological features. mcp-1   (a/g   -2518),  ccr2   (+/64i), ...

BACKGROUND AND PURPOSE Recent studies have suggested that chronic inflammation actively participates in cerebral aneurysm (CA) formation. Macrophages accumulate in CA walls and express proinflammatory genes promoting CA progression, but the molecular mechanisms of monocyte/macrophage recruitment into CA walls remain to be elucidated. METHODS Monocyte chemoattractant protein-1 (MCP-1) expressi...

PURPOSE We studied serum monocyte chemotactic protein-1 (MCP-1) levels in breast cancer patients in relationship to their clinicopathologic variables and immune response to a /neu E75 vaccine. EXPERIMENTAL DESIGN We measured MCP-1 levels in 32 /neu(+) breast cancer patients before and after vaccination with a /neu E75 peptide + granulocyte macrophage colony-stimulating factor vaccine. Clinica...

The interaction of the polycationic rabbit alveolar macrophage cationic proteins MCP-1 and MCP-2 (or their identical neutrophil equivalents NP-1 and NP-2) with the surface of Pseudomonas aeruginosa was investigated. Both proteins bound avidly to purified lipopolysaccharide, as judged by their ability to competitively displace the probe dansyl polymyxin with 50% inhibition (I50) values of 2 to 3...

Monocyte chemoattractant protein-1 (MCP-1) and transforming growth factor (TGF)-beta1 are critical mediators of renal injury by promoting excessive inflammation and extracellular matrix deposition, thereby contributing to progressive renal disease. In renal disease models, MCP-1 stimulates the production of TGF-beta1. However, a potential role for TGF-beta1 in the regulation of MCP-1 production...

BACKGROUND/AIMS Chemokines are a family of low molecular weight cytokines that attract and activate leucocytes. The CC chemokines act on eosinophils, basophils, monocytes, and lymphocytes, suggesting that they play an important part in allergic diseases. The aims of this study were to investigate the expression of the CC chemokines, RANTES, eotaxin, monocyte chemotactic protein (MCP) 1, MCP-2, ...

Chemotactic cytokines of the CC subfamily (CC chemokines) are considered as major mediators of allergic inflammation owing their actions on basophil and eosinophil leukocytes. The monocyte chemotactic protein (MCP) 1 is a potent inducer of mediator release from basophils but is inactive on eosinophils. To obtain information on the structural determinants of the activities of MCP-1, we have synt...

Monocyte migration and activation are regulated by monocyte chemoattractant protein-1 (MCP-1). Prior studies have shown MCP-1 expression is modulated by a variety of ligands that act through extracellular receptors. In the current study, we show 9-cis retinoic acid (RA), a ligand for the nuclear hormone receptor retinoid X receptor (RXR) and retinoic acid receptor (RAR), markedly induces the ex...

Data on estimating the vertical dimension of occlusion（VDO）for fabricating a complete denture based tongue pressure, which is related to masticatory and swallowing functions, are scarce. This study aimed examine changes in pressure raising or lowering VDO from most comfortable position（MCP）. Ten edentulous, including Eichner C3, patients with existing dentures（six men four women; mean age, 78.6...
