PMID- 12838504 OWN - NLM STAT- MEDLINE DCOM- 20031118 LR - 20190508 IS - 0894-1491 (Print) IS - 0894-1491 (Linking) VI - 43 IP - 2 DP - 2003 Aug TI - Tumor necrosis factor is required for RANTES-induced astrocyte monocyte chemoattractant protein-1 production. PG - 119-27 AB - Astrocytes respond to stimulation with the chemokine RANTES (regulated on activation, normal T cell expressed) by production of a series of cytokines and chemokines, including tumor necrosis factor-alpha (TNF-alpha) and monocyte chemoattractant protein-1 (MCP-1). In the present study we demonstrate that RANTES induces TNF, which in turn stimulates subsequent production of MCP-1. TNF-R1 (p55) serves as the principal receptor responsible for MCP-1 synthesis. The results define an astrocyte proinflammatory cascade that amplifies synthesis of proinflammatory mediators. The implications of these findings to inflammatory diseases of the central nervous system are discussed. CI - Copyright 2003 Wiley-Liss, Inc.
