Fig. 2From: An update on reactive astrocytes in chronic painChanges in the morphology and function of astrocytes after noxious stimulation and nerve injury. Based on phenotypic changes of astrocytes, astrocyte can be divided into reactive and scar-forming astrocyte, reactive astrocyte can be further classified by A1 and A2 astrocyte. Based on functional changes of astrocyte, astrocytopathy can be divided into astrocytes atrophy with loss of function, pathological remodelling of astrocytes and reactive astrogliosis based on functional cellular responsesBack to article page
