The role of integrins in human cytomegalovirus (HCMV)-infected monocytes.

ABSTRACT: We have established that human cytomegalovirus (HCMV) infection modulates the biology of target primary blood monocytes, allowing HCMV to use monocytes as 'vehicles' for its systemic spread. HCMV infection of monocytes results in rapid induction of PI(3)K and NF-kB activity. Integrins, which are upstream of the PI(3)K and NF-kB pathways, were shown to be involved in HCMV binding to and entry into fibroblasts, suggesting that receptor-ligand-mediated signaling following viral binding to integrins on monocytes could trigger the functional changes seen in infected monocytes. We now show that integrin engagement and the activation of the integrin/Src-signaling pathway is essential for the induction of HCMV-infected monocyte motility. To investigate how integrin engagement by HCMV triggers
