Regulation of JAK|[ndash]|STAT signalling in the immune system

Ke Shuai & Bin Liu

The cytokine-activated Janus kinase (JAK)–signal transducer and activator of transcription (STAT) pathway has an important role in the control of immune responses. Dysregulation of JAK–STAT signalling is associated with various immune disorders. The signalling strength, kinetics and specificity of the JAK–STAT pathway are modulated at many levels by distinct regulatory proteins. Here, we review recent studies on the regulation of the JAK–STAT pathway that will enhance our ability to design rational therapeutic strategies for immune diseases.
