Microglia have been implicated in neuropathic pain. They become activated in response to nerve injury, as demonstrated by several animal models. [30] Activated microglia release substances that excite pain-sensitive neurons, including prostaglandins and reactive oxygen species, through the purinergic signaling mechanisms.
Microglia are a type of glial cell located throughout the brain and spinal cord of the central nervous system (CNS). [1] Microglia account for about 10–15% of cells found within the brain. [2] As the resident macrophage cells, they act as the first and main form of active immune defense in the CNS. [3]
Microglia are the second most prominent cell type present within the glial scar. They are the nervous system analog of immune system macrophages.Microglia rapidly activate near the injury and secrete several cytokines, bioactive lipids, coagulation factors, reactive oxygen intermediates, and neurotrophic factors.

In the healthy brain, cells secrete cytokines to produce a local inflammatory environment to recruit microglia and clear the infection or injury. However, in neuroinflammation, cells may have sustained release of cytokines and chemokines which may compromise the blood–brain barrier. [ 11 ]
In the healthy central nervous system, microglia processes constantly sample all aspects of their environment (neurons, macroglia and blood vessels). In a healthy brain, microglia direct the immune response to brain damage and play an important role in the inflammation that accompanies the damage.
