Abstract
The increased migration of peripheral blood mononuclear cells (PBMNCs) across a fibronectin (FN) matrix in response to the chemokines RANTES, MIP- 1α and MCP-1 is antagonized by interferon beta-1b (IFN β-1b): MCP-1 treatment of PBMNCs elevates their mRNA level and secretion of a matrix degrading enzyme, matrix metalloproteinase (MMP)-9, which is abrogated by IFN β-1b. The clinical benefits of IFN β-1b treatment in multiple sclerosis patients may in part be a result of this drug's ability to decrease the migration of PBMNCs in spite of a chemotactic gradient. Furthermore, the elevation of MMP-9 production by PBMNCs may be an important mechanism of action of chemokines.
