The monocyte chemotactic protein 3 (MCP-3) belongs to the MCP subgroup of the CC chemokines and promotes chemotaxis of immune cells. MCP-1 is believed to play an important role in monocyte infiltration into tumor tissues; however, the relationship between tumor-infiltrating macrophage/microglia (TIM/M) and the expression of chemokines has not been investigated in detail in human glioma samples;...

Monocyte chemotactic protein (MCP)-1 and MCP-2, two closely related CC chemokines, are important mediators of monocyte and lymphocyte migration. These chemokines are secreted by various normal cell types, including fibroblasts, epithelial cells, and leukocytes, as well as by tumor cells. After stimulation with different cytokines and cytokine inducers the MCP-2 production levels are always lowe...

A novel human CC chemokine complementary DNA was identified in a library constructed from human fetal RNA, cloned into a baculovirus vector, and expressed in Sf9 insect cells. The mature recombinant protein that was released had the NH2-terminal sequence pyro-QPDALNVPSTC...and consisted of 75 amino acids. Minor amounts of two variants of 77 and 82 residues (NH2 termini: LAQPDA...and FNPQGLAQPDA...

Monocyte chemoattractant protein (MCP)-1 plays a critical role in innate immunity by directing the migration of monocytes into inflammatory sites. Recent data indicated a function for this chemokine in adaptive immunity as a regulator of T cell commitment to T helper cell type 2 (Th2) effector function. Studies in a Th1-dependent animal model, experimental autoimmune encephalomyelitis (EAE), sh...

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...
