Decrease of natural antiphosphorylethanolamine antibodies by injection of C-reactive protein.

abstract：:Two crucial mediators of monocyte activation by lipopolysaccharide (LPS) are the acute phase plasma factor, lipopolysaccharide binding protein (LBP) and cell-surface-expressed CD14. Whether macrophage (M phi) recognized and respond to LPS in a similar manner is unknown. Here we show that human monocyte-derived M phi r...
