IL-2 Regulation of Effector and Memory CD8 T cell Differentiation– A balancing act
- 1Department of Pediatrics, School of Medicine, University of Washington, United States
Interleukin-2 (IL-2) regulates key aspects of CD8 T cell biology – signaling through distinct pathways IL-2 triggers critical metabolic and transcriptional changes that lead to a spectrum of physiological outcomes such as cell survival, proliferation and effector differentiation. In addition to driving effector differentiation, IL-2 signals are also critical for formation of long-lived CD8 T cell memory. This review discusses a model of rheostatic control of CD8 T cell effector and memory differentiation by IL-2, wherein the timing, duration, dose and source of IL-2 signals are considered in fine-tuning the balance of key transcriptional regulators of cell fate.
