Salvianolic acid A suppresses CCL-20 expression in TNF-α-treated macrophages and ApoE-deficient mice.

Objectives: The CC chemokine ligand-20 (CCL-20)/macrophage inflammatory protein-3α has been seen as one of the most important chemokines and played a key role in atherogenesis, but the mechanism that underlies the regulation of CCL-20 has not been established clearly yet. The aim of this study was to investigate the influence of salvianolic acid A (SAA) on the expression of CCL-20 in macrophages and ApoE-deficient (ApoE) mice.

Methods: The expression of CCL-20 was detected both at protein and messenger RNA levels in RAW264.
