Role of microglia in neuroinflammation after traumatic brain injury and its significance in nerve regeneration / 中华神经医学杂志

The secondary damage after traumatic brain injury (TBI) involves a variety of pathological processes, and the inflammatory response in the nervous system is an important factor which affects nerve repair and regeneration. As the innate immune cell in the nervous system, microglia (MG) plays an important role in the entire neuroinflammatory environment by regulating the activation state of MG and changing the inflammatory response in the direction of promoting nerve repair and regeneration, which has great potential in treatment of TBI. This article reviews the inflammatory response of the nervous system after TBI and the reactivity of MG, as well as their significance in nerve repair and regeneration.
