N2 - Monocyte chemoattractant protein-1 (MCP-1), purified from glioma cell line (U-105MG) culture fluid, attracts monocytes but not neutrophils. Macrophage accumulation is one of the pathological features of meningioma. To investigate the mechanism of macrophage infiltration into meningioma, the expression and localization of MCP-1 in 16 cases of meningioma were studied using Northern blot analysis and immunohistochemistry. Seven of 16 meningiomas expressed MCP-1 messenger ribonucleic acid and protein, and some degree of macrophage infiltration was seen in all 16 meningiomas. There was a relationship between MCP-1 expression and the degree of macrophage infiltration; MCP-1 was strongly expressed in meningiomas with a high degree of macrophage infiltration. Sometimes the meningioma was accompanied by perifocal edema; a correlation between macrophage infiltration into brain tumors and perifocal edema has already been reported. It was found that the degree of MCP-1 expression is not correlated with the extent of perifocal edema. The authors' findings suggest that MCP-1 plays an important role in macrophage infiltration into meningioma.
