  "account": "Parkinson's disease is increasingly linked to vascular dysfunction, but the role of vascular pathology in disease progression is not well understood. Researchers created a 3D model of brain tissue that included engineered neurospheroids and a self-assembled vascular network to better capture the neurovascular interface. By introducing preformed fibrils of α-synuclein into the engineered blood vessels, they were able to study the vascular contribution to Parkinson's disease pathology. The results showed that exposing the vascular network to α-synuclein fibrils led to endothelial barrier disruption, vascular leakage, inflammation, and vascular regression. Importantly, this vascular damage also triggered intraneuronal aggregation of α-synuclein within the neurospheroids, indicating that vascular dysfunction may help expose neural tissue to pathogenic α-synuclein. This new modeling approach provides a versatile platform for investigating how vascular issues can contribute to the progression of neurodegenerative diseases like Parkinson's.",
  "summary": "Neurodegenerative diseases are increasingly associated with vascular dysfunction beyond progressive neuronal degeneration, yet how vascular pathology contributes to disease progression remains poorly understood, largely due to the lack of a neurodegenerative disease model capable of capturing neuronal pathology alongside associated vascular dysfunction. Here, we developed a microengineered 3D…",
