The immunological synapse and Rho GTPases

Curr Top Microbiol Immunol. 2005;291:61-90. doi: 10.1007/3-540-27511-8_5.

Abstract

Rho GTPases are molecular switches controlling a broad range of cellular processes including lymphocyte activation. Not surprisingly, Rho GTPases are now recognized as pivotal regulators of antigen-specific T cell activation by APCs and immunological synapse formation. This review summarizes recent advances in our understanding of how Rho GTPase-dependent pathways control T lymphocyte motility, polarization and activation.
