Relapsing-remitting multiple sclerosis (MS) 2 2 MS: multiple sclerosis. is characterized by phases of acute neuroinflammation followed by spontaneous remission. Termination of inflammation is accompanied by an influx of regulatory T cells (T regs ). 3 3 T regs : regulatory T cells. The molecular mechanisms responsible for directing T regs into the inflamed CNS tissue, however, are incompletely understood. In an MS mouse model we show that the stress kinase general control non-derepressible 2 (GCN2), 4 4 GCN2: general control non-derepressible 2. expressed in T cells, contributes to the resolution of autoimmune neuroinflammation. Failure to recover from acute inflammation was associated with reduced frequencies of CNS-infiltrating T regs . GCN2 deficient T regs displayed impaired migration to a CCL2 gradient. These data suggest an important contribution of the T cell stress response to the resolution of autoimmune neuroinflammation. [ABSTRACT FROM AUTHOR]
