Caspase-8: clipping off RIG-I signaling.

abstract：:Cdc42 and WASP are critical regulators of actin polymerization whose function during T cell signaling is poorly understood. Using a novel reagent that specifically detects Cdc42-GTP in fixed cells, we found that activated Cdc42 localizes to the T cell:APC contact site in an antigen-dependent manner. TCR signaling alon...

Although Nod2 and the related sensor, Nod1, direct ATG16L1 to initiate anti-bacterial autophagy, whether ATG16L1 affects Nod-driven inflammation has not been examined. Here, we uncover an unanticipated autophagy-i...
