Previous results from this laboratory revealed the presence of high-affinity saturable binding sites for monocyte chemoattractant protein-1 (MCP-1) along human brain microvessels (Andjelkovic et al., 1999; Andjelkovic and Pachter, 2000), which suggested that CC chemokine receptor 2 (CCR2), the recognized receptor for this chemokine, was expressed by the brain microvascular endothelium. To test ...

The present study focused on the molecular signaling pathways of monocyte chemoattractant protein-1 (MCP-1) induction by interleukin-4 (IL-4) in human umbilical vein endothelial cells (HUVEC). RT-PCR showed that MCP-1 mRNA accumulation was markedly increased in IL-4-treated HUVEC in a time- and dose-dependent manner. Antioxidants, such as pyrrolidine dithiocarbamate (PDTC) and N-acetylcysteine ...

The monocyte chemotactic protein-1 (MCP-1) receptor (MCP-1R) is expressed on monocytes, a subpopulation of memory T lymphocytes, and basophils. Two alternatively spliced forms of MCP-1R, CCR2A and CCR2B, exist and differ only in their carboxyl-terminal tails. To determine whether CCR2A and CCR2B receptors function similarly, Jurkat T cells were stably transfected with plasmids encoding the huma...

Chemokines, including RANTES/CCL5 and MCP-1/CCL2, are highly expressed in the joints of patients with rheumatoid arthritis, and they promote leukocyte migration into the synovial tissue. This study was conducted to determine whether the inhibition of RANTES and MCP-1 therapeutically was capable of ameliorating rat of adjuvant-induced arthritis (AIA). Postonset treatment of AIA using a novel inh...

d'Anjou cv. pear fruit (Pyrus communis L.) exposed at harvest to 0, 0.42, 4.2, or 42 micromol m(-)(3) 1-methylcyclopropene (1-MCP) for 12 h at 20 degrees C were stored at 1 degrees C for up to 8 months. After storage, half of the fruit was continuously exposed to ethylene (0.45 or 4-18 mmol m(-)(3)) for 7 days at 20 degrees C. All fruit treated with 1-MCP had lower respiration and ethylene prod...

Abstract Background Metoclopramide (MCP) is a dopamine D 2 ‐receptor antagonist, mainly used to treat post‐operative or chemotherapy‐induced nausea. While it very effective in the cure of gastric symptoms, MCP can cause severe neurologic side effects. Furthermore, there growing evidence for arrhythmic effects resulting from inhibitory on cardiac sodium and potassium channels. Methods Results Th...

Monocyte chemotactic protein-1 (MCP-1), a specific chemoattractant for monocytes, has been thought to play an important role in the recruitment and accumulation of monocytes within the glomerulus seen in glomerular diseases. This study examined the role of tumor necrosis factor (TNF)-alpha-mediated cellular signal transduction pathways on mesangial cell MCP-1 gene expression and monocyte migrat...

Monocyte chemoattractant protein-1 (MCP-1)/monocyte chemotactic and activating factor (MCAF) has been suggested to promote atherogenesis. The effects of in vivo neutralization of MCP-1 in a rat model were examined in an effort to clarify the role of MCP-1 in the development of neointimal hyperplasia. Competitive polymerase chain reaction analysis revealed maximum MCP-1 mRNA expression at 4 hour...

Both monocyte chemoattractant protein-1 (MCP-1), a member of chemokine family, and angiotensinogen, a precursor of angiotensin (ANG) II, are produced by adipose tissue and increased in obese state. MCP-1 has been shown to decrease insulin-stimulated glucose uptake and several adipogenic genes expression in adipocytes in vitro, suggesting its pathophysiological significance in obesity. However, ...

PURPOSE To investigate the effect of monocyte chemoattractant protein-1 (MCP-1)/CC chemokine ligand 2 on aqueous humor outflow facility. METHODS Aqueous humor outflow facility was measured in enucleated porcine eyes in a constant pressure perfusion system with or without MCP-1 (1600 ng/mL). Expression of CCR2, an MCP-1 receptor, in Schlemm's canal endothelial (SCE) cells was examined by rever...
