Multiple pathways leading from the T-cell antigen receptor to the actin cytoskeleton network.
Dynamic rearrangements of the actin cytoskeleton, following T-cell antigen receptor (TCR) engagement, provide the structural matrix and flexibility to enable intracellular signal transduction, cellular and subcellular remodeling, and driving effector functions. Recently developed cutting-edge imaging technologies have facilitated the study of TCR signaling and its role in actin-dependent processes. In this review, we describe how TCR signaling cascades induce the activation of actin regulatory proteins and the formation of actin networks, and how actin dynamics is important for T-cell homeostasis, activation, migration, and other effector functions.
