In the PE patients, the mRNA expression of CD14, a mononuclear cell surface antigen, was markedly up-regulated and that of CD74, a macrophage activating factor, was also significantly up-regulated. In addition, the mRNA expressions related to Fc fragment of surface receptors (FCGR2A, FCGR2B, FCGR2C, ITGAL and SCARB1) were largely increased significantly ( Figure 2 ).
