内容記述 | Aging is intimately associated with deposition of abnormal proteins in the brain exemplified by amyloid-beta and tau, and excess accumulation of these aggregates eventually leads to the onset and progression of Alzheimer’s disease and other neurodegenerative dementias. Molecular links between protein deposition and neuronal deteriorations are yet to be clarified, while a consensus hypothetical view is that protein aggregation triggers chain reactions of key pathological processes including neuroinflammation and aberrant neurotransmissions, resulting in synaptic dysfunction and neuronal death. This pathogenetic signal cascade has been visualized in living human and animal brains using positron emission tomography (PET) and radiotracers targeting essential components in the key processes. By near-simultaneous observations of multiple key processes with PET, it has been recently revealed that downstream processes also mechanistically regulate upstream processes, implying a ‘backflow’ of the cascade. Indeed, causal relations could be found between any two of the key processes, thereby rationalizing a network concept rather than cascade-like one-way signaling. Hence, molecular and cellular etiology of age-related brain diseases could be analyzed as emergence of pathological but ordered network of key processes in the brain, instead of disruption of physiological and homeostatic orders. | |||||
