外文摘要：Traumatic brain injury,chronic traumatic encephalopathy,and Alzheimer's disease are three distinct neurological disorders that share common pathophysiological mechanisms involving neuroinflammation.One sequela of neuroinflammation includes the pathologic hyperphosphorylation of tau protein,an endogenous microtubule-associated protein that protects the integrity of neuronal cytoskeletons.Tau hyperphosphorylation results in protein misfolding and subsequent accumulation of tau tangles forming neurotoxic aggregates.These misfolded proteins are characteristic of traumatic brain injury,chronic traumatic encephalopathy,and Alzheimer's disease and can lead to downstream neuroinflammatory processes,including assembly and activation of the inflammasome complex.Inflammasomes refer to a family of multimeric protein units that,upon activation,release a cascade of signaling molecules resulting in caspase-induced cell death and inflammation mediated by the release of interleukin-1β cytokine.One specific inflammasome,the NOD-like receptor protein 3,has been proposed to be a key regulator of tau phosphorylation where it has been shown that prolonged NOD-like receptor protein 3 activation acts as a causal factor in pathological tau accumulation and spreading.This review begins by describing the epidemiology and pathophysiology of traumatic brain injury,chronic traumatic encephalopathy,and Alzheimer's disease.Next,we highlight neuroinflammation as an overriding theme and discuss the role of the NOD-like receptor protein 3 inflammasome in the formation of tau deposits and how such tauopathic entities spread throughout the brain.We then propose a novel framework linking traumatic brain injury,chronic traumatic encephalopathy,and Alzheimer's disease as inflammasome-dependent pathologies that exist along a temporal continuum.Finally,we discuss potential therapeutic targets that may intercept this pathway and ultimately minimize long-term neurological decline.
