LPS enhances expression of CD204 through the MAPK/ERK pathway in murine bone marrow macrophages

These results suggest that LPS may increase Ac-LDL uptake and enhance CD204 expression through MAPK/ERK activation and CD36 expression through an ERK-independent pathway. Since MEK inhibitors block CD204 expression in mouse BM macrophages only under LPS treatment but not under normal conditions, a MEK inhibitor might be a good candidate compound for the treatment of LPS-induced atherosclerosis.
