论坛导读:脑淀粉样血管病(Cerebral amyloid angiopathy, CAA)在老年人的大脑中是一种常见的以β淀粉样蛋白(Amyloid β,Aβ)沉积于颅内微血管(软脑膜动脉、皮质小动脉、毛细血管)为特点的神经系统变性疾病。CAA是一组异质性较高的疾病,目前其发...

Amyloid Plaques in Alzheimer's Disease Understanding Cerebral Amyloid Angiopathy Lesson Summary Frequently Asked Questions What removes amyloid plaque? In a healthy brain, the glial cells and the astrocytes are responsible for cleaning up the buildup of proteins around the neurons; however, they fail...
Amyloid angiopathy can also lead to a large area of bleeding in the brain, which can be life-threatening.3 Diagnosis The most reliable method used to diagnose amyloid angiopathy is a brain biopsy, which is not a practical procedure. A brain biopsy is a surgical procedure that carries a risk...
Masafumi Ihara3 & Hideo Saji1 Cerebral amyloid angiopathy (CAA), characterized by the deposition of amyloid aggregates in the walls of cerebral vasculature, is a major factor in intracerebral hemorrhage and vascular cognitive impairment and is also associated closely with Alzheimer's disease (AD...
We found that bone marrow cells (BMCs) transplanted from APPswe/PS1dE9 transgenic mice into wild-type (Wt) mice at 3 months of age continuously expressed human Aβ in the blood, and caused AD phenotypes including Aβ plaques, cerebral amyloid angiopathy (CAA), tau hyperphosphorylation, ...
Alzheimer's disease (AD) is characterized by the accumulation of amyloid-β (Aβ) as senile plaques and cerebral amyloid angiopathy, and hyperphosphorylated tau (hp-tau) as neurofibrillary tangles in the brain. The AD-related pathology has been reported in several non-human animals, and most ...

Central nervous system dysfunction is common in longstanding hereditary transthyretin amyloidosis (ATTRv) caused by the V30M (p.V50M) mutation. Neuropathology studies show leptomeningeal amyloid deposition and cerebral amyloid angiopathy (CAA). Brain MRI is widely used in the assessment of Aβ associat...
