Roles of microglia in SAE and sepsis-associated chronic pain. During sepsis, microglia can be activated by inflammatory mediators, adjacent cells and neurotransmitters. Then, activated microglia integrate neuroinflammation and cause neuronal dysfunctions via secreted inflammatory mediators or glutamate to lead to SAE and chronic pain. Glutamate may form a positive feedback mechanism in microglia activation.
