Objective To investigate the effects of B-type natriuretic peptides (BNP) on expression of monocyte chemoattractant protein-1(MCP-1) in rat peritoneal macrophages and to identify the inflammation-mediated effects of BNP in macrophages. Methods Peritoneal macrophages of primary culture were treated with BNP
BNP+HS-142-1
or BNP+TNF-α+HS-142-1. The protein expression of MCP-1 was measured by Western blot. Results BNP enhanced the MCP-1 protein expression in macrophages
and this effect could be abrogated by HS-142-1. In addition
BNP could inhibit TNF-α induced MCP-1 expression. Conclusion BNP can induce the MCP-1 protein expression in macrophages
suggesting BNP has a pro-inflammatory effect. However
BNP also can inhibit TNF-α induced MCP-1. These findings suggest that the effect of inflammation-mediated by BNP is biphasic though the mechanism is still unclear.
