Cerebral Amyloid Angiopathy: Emerging Evidence for Novel Pathophysiology and PathogenesisCerebral amyloid angiopathy (CAA) is cerebrovascular amyloid deposition being classified into several types according to the amyloid protein involved. Of these, sporadic amyloid 尾-protein (A尾)-type CAA is most ...
Aβ特定残基的突变可能是导致CAA的遗传因素,同时Aβ沉积也在阿尔茨海默症(AD)发病过程中起着重要作用,二者存在“剪不断理还乱”的重叠关系。 CAA的Boston诊断标准2.0版 The Boston criteria version 2.0 for cerebral amyloid angiopathy: ...
Cerebral amyloid angiopathy (CAA) is a common disease in older adults that contributes to dementia1–3. In CAA, amyloid beta (Aβ) is deposited along either capillaries (type 1) or vessel walls (type 2)4, with the underlying pathophysiology incompletely

Cerebral amyloid angiopathy (CAA) is a common, yet frequently overlooked, pathology associated with AD. CAA manifests with deposition amyloid-beta (Aβ) within the smooth muscle layer of cerebral arteries and arterioles. The role of Aβ in AD and CAA pathophysiology has long been controversial....

(before accumulation of Aβ in and around vascular cells—cerebral amyloid angiopathy—leads to pericyte loss), as is also seen in live imaging of CBF in AD patients [107]. In contrast, in patients lacking Aβ and tau deposition, capillaries showed a larger diameter near the pericyte soma,...
In this manuscript, we provide a comprehensive review of existing animal models for CAA, which can aid in understanding the pathophysiology of CAA and explore the response to potential therapies. 展开 关键词: Animal models Amyloid-β Cerebral amyloid angiopathy Transgenic mice ...
(DPA), while blood markers of systemic inflammation appear to be associated with cerebral amyloid angiopathy (CAA). Here, we discuss recent findings in the pathophysiology of inflammaging and their effects on the development of age-related CSVD. Furthermore, we speculate the inflammaging as a ...
Senile plaques (SP) and amyloid angiopathy (AA) were detected in 36 (55%) and 19 (29%) patients, respectively. Also, cerebral amyloid deposits from the brains of seven patients with dementia and five patients without were studied in serial sections stained with Bodian, modified Bielschowsky, ...
