Synaptic asymmetry to go

摘要

Cell polarity is critical for T lymphocyte movement during their hunt for antigen-bearing cells and for infected target cells. In this issue of Cell, Yeh et al. (2008) now reveal a direct link between T cell polarity and the production of proinflammatory cytokines in mice lacking the class I MHC-restricted T cell-associated molecule (Crtam).
