Conclusions
This study provides the first evidence that (1) lysoPC activates PKD, (2) PKD2 has a novel role in p38 activation, and (3) the PKD2-activated p38 pathway is responsible for lysoPC-induced migration of THP-1 cells and human monocytes. Thus, PKD is a novel and functional intracellular regulator in both lysoPC signaling and monocyte migration. These results suggest a new role for PKD2 in the development of atherosclerosis and other inflammatory diseases.
Objective
Monocyte activation and migration are crucial events in the development of atherosclerosis and other inflammatory diseases. This study examined the role of protein kinase D (PKD) in monocyte migration. Method and
