Gene delivery of interleukin 2 treats neuro-inflammation in traumatic brain injury

Using a gene-delivery system, we show that ectopic expression of interleukin 2 (IL-2) within reactive astrocytes stimulates brain-specific expansion of resident regulatory T cells. Such gene delivery protects against neuroinflammation in several mouse models of disease and injury, with potential implications for patients with traumatic brain injuries.
