Uropods, in immunology, refer to the hind part of polarized leukocytes, mostly involved in cell-to-cell interaction, cell activation and apoptosis. Leukocyte polarization is an important requirement for migration, activation and apoptosis.

Coordinated RhoA signaling at the leading edge and uropod is required for T cell transendothelial migration.
Lipid rafts mediate biosynthetic transport to the T lymphocyte uropod subdomain and are necessary for uropod integrity and function.
