text: Migrating lymphocytes acquire a polarized phenotype with a leading and a trailing
edge, or uropod. Although in vitro experiments in cell lines or activated primary
cell cultures have established that Rho-p160 coiled-coil kinase (ROCK)-myosin
II-mediated uropod contractility is required for integrin de-adhesion on two-dimensional
surfaces and nuclear propulsion through narrow pores in three-dimensional matrices,
less is known about the role of these two events during the recirculation of primary,
nonactivated lymphocytes. Using pharmacological antagonists of ROCK and myosin
II, we report that inhibition of uropod contractility blocked integrin-independent
mouse T cell migration through narrow, but not large, pores in vitro. T cell crawling
on chemokine-coated endothelial cells under shear was severely impaired by ROCK
inhibition, whereas transendothelial migration was only reduced through endothelial
cells with high, but not low, barrier properties. Using three-dimensional thick-tissue
imaging and dynamic two-photon microscopy of T cell motility in lymphoid tissue,
we demonstrated a significant role for uropod contractility in intraluminal crawling
and transendothelial migration through lymph node, but not bone marrow, endothelial
cells. Finally, we demonstrated that ICAM-1, but not anatomical constraints or
integrin-independent interactions, reduced parenchymal motility of inhibitor-treated
T cells within the dense lymphoid microenvironment, thus assigning context-dependent
roles for uropod contraction during lymphocyte recirculation.
