An aminoacyl-tRNA synthetase-associated factor, p43, was recently shown to be secreted to induce a proinflammatory response. Because a proinflammatory response involves the cell-cell adhesion between endothelial and immune cells, we first examined the mechanism of p43-induced cell-cell adhesion of myelomonocytic leukemia cells. Intercellular adhesion molecule-1 (ICAM-1) was up-regulated by p43 and mediated p43-induced cell-cell adhesion via the interaction with LFA-1 or Mac-1. We also investigated p43-stimulated signaling pathways involved in the homotypic THP-1 cell adhesion. Because the specific inhibitors for PI3-K (phosphatidylinositol 3-kinase), ERK (extracellular signal-regulating kinase), and p38 MAPK (mitogen-activated protein kinase) blocked p43-stimulated ICAM-1 expression and homotypic THP-1 cell adhesion, these kinases were responsible for p43-induced cell-cell adhesion. p43-Dependent activation of ERK was inhibited by PI3-K inhibitors, and the activation of p38 MAPK was not. Thus, the results of this work suggest that p43 should induce cell-cell adhesion via the PI3-K/ERK- and p38 MAPK-dependent up-regulation of ICAM-1.
