title: [Effect of the mitogen-activated kinase inhibitors on monocyte protein-1-stimulated chemotaxis of cells].
abstract: Monocyte chemoattractant protein (MCP-1) is a major chemoattractant for monocytes and T-lymphocytes although it can cause migration of the HUVECs. We used monocytic cell line THP-1, monocytes of human peripheral blood, and HUVECs to study MCP-1 receptor-mediated cell migration. We showed that THP-1 and the monocytes chemotaxis was decreased in presence of specific inhibitors of p 38 MAP-kinase. Furthermore, it was almost completely diminished by inhibitor of tyrosine kinases. In contrast, MCP-1-stimulated migration of HUVECs was abrogated by specific inhibitor of ERK1/2 MAP-kinases and, to a lesser extent, by blocking tyrosine kinases. These results suggest that intracellular signal pathways activated by MCP-1 in monocytes and HUVECs, are distinct.
