Syndapin-2 mediated transcytosis of amyloid-beta across the blood brain barrier

# metadata.dc.description.abstract[].value
A deficient transport of amyloid-beta across the blood-brain barrier, and its diminished clearance from the brain, contribute to neurodegenerative and vascular pathologies, such as Alzheimer's disease and cerebral amyloid angiopathy, respectively. At the blood-brain barrier, amyloid-beta efflux transport is associated with the low-density lipoprotein receptor-related protein 1. However, the precise mechanisms governing amyloid-beta transport across the blood-brain barrier, in health and disease, remain to be fully understood. Recent evidence indicates that the low-density lipoprotein receptor-related protein 1 transcytosis occurs through a tuhulation-mediated mechanism stabilized by syndapin-2. Here, we show that syndapin-2 is associated with amyloid-beta clearance via low-density lipoprotein receptor-related protein 1 across the blood-brain barrier. We further demonstrate that risk factors for Alzheimer's disease, amyloid-beta expression and ageing, are associated with a decline in the native expression of syndapin-2 within the brain endothelium. Our data reveals that syndapin-2-mediated pathway, and its balance with the endosomal sorting, are important for amyloid-beta clearance proposing a measure to evaluate Alzheimer's disease and ageing, as well as a target for counteracting amyloid-beta build-up. Moreover, we provide evidence for the impact of the avidity of amyloid-beta assemblies in their trafficking across the brain endothelium and in low-density lipoprotein receptor-related protein 1 expression levels, which may affect the overall clearance of amyloid-beta across the blood-brain barrier.
