In this article, we present our previous research, which highlighted adenosine triphosphate(ATP) as the cause of neuropathic pain during the acute phase of neuromyelitis optica spectrum disorder(NMOSD). In NMOSD pathology, damageassociated molecular patterns(DAMPs), including ATP, are released from damaged astrocytes, triggering the activation of innate immune cells. ATP is a central mediator of acute pain in NMOSD.
