CELL BIOLOGY: Kinasing and Clipping Down the NF-B Trail
Nicolai S. C. van Oers and Zhijian J. Chen
Activation of T cells is a key requirement for a successful innate or adaptive immune response to pathogenic insult. T cell stimulation results in activation of the master transcription factor NF-B by a complicated signaling pathway that is only partially understood. In their Perspective, van Oers and Chen discuss new findings that implicate the kinase PDK1 (Lee et al.) and a caspase (Su et al.) as crucial players in the T cell signaling pathway that activates NF-B.
