Hypoxia down-regulates MCP-1 expression: implications for macrophage distribution in tumors.

abstract：:Although HDPs were originally hypothesized to act as antimicrobial agents, they also have been shown to broadly modulate the immune response through the activation of different cell types. We recently developed a series of novel, synthetic peptides, termed IDRs, which are conceptually based on a natural HDP, bovine ba...
