Single-nucleus RNA-seq of microvessel-enriched vascular cells and corresponding parenchyma from frontal cortex samples

ABSTRACT: Vascular cell types are under-represented in standard single-nucleus RNA-Seq studies of human frozen post-mortem brain tissue. Using a novel microvessel-enrichment procedure allows to obtain highly purified fractions of vascular cell types and their corresponding parenchymal fraction of the same post-mortem brain tissue sample.

snRNA-seq of nuclei isolated with microvessel-enrichment procedure applied to frozen post-mortem brain tissue

Project description:Vascular cell types are under-represented in standard single-nucleus RNA-Seq studies of human frozen post-mortem brain tissue. The dataset represents the pilot data obtained with the first version of a microvessel- enrichment protocol to obtain a higher percentage of endothelial cells as the key cellular component of the blood-brain barrier.

Brain microvessel: Alzheimer disease vs normal

Project description:The enigma that is Alzheimer's disease (AD) continues to present daunting challenges for effective therapeutic intervention. The lack of disease-modifying therapies may, in part, be attributable to the narrow research focus employed to understand this complex disease. Most studies into disease pathogenesis are based on a priori assumptions about the role of AD lesion-associated proteins such as amyloid-? and tau. However, the complex disease processes at work may not be amenable to single-target therapeutic approaches. Genome-wide expression studies provide an unbiased approach for investigating the pathogenesis of complex diseases like AD. A growing literature suggests a role for cerebrovascular contributions to the pathogenesis of AD. The objective of the current study is to examine human brain microvessels isolated from AD patients and controls by microarray analysis. Differentially expressed genes with more than 2-fold change are used for further data analysis. Gene ontology analysis and pathway analysis algorithms within GeneSpringGX are employed to understand the regulatory networks of differentially expressed genes. Twelve matched pairs of AD and control brain microvessel samples are hybridized to Agilent Human 4 × 44 K arrays in replication. We document that more than 2,000 genes are differentially altered in AD microvessels and that a large number of these genes map to pathways associated with immune and inflammatory response, signal transduction, and nervous system development and function categories. These data may help elucidate heretofore unknown molecular alterations in the AD cerebromicrovasculature. Two condition experiment, diseased vs normal, our study included 12 pairs of biological replicates and each pair was repeated with dye swap making total of 24 double channel hybridizations. we excluded 4 samples for not passing QC. So 20 samples were included in the data analysis.

Proteome analysis of microvessels from CAA and AD patients

Project description:Cerebral amyloid angiopathy (CAA) is an age-related condition and a major cause of intracerebral hemorrhage and cognitive decline that shows close links with Alzheimer's disease (AD). CAA is characterized by the aggregation of amyloid-β (Aβ) peptides and formation of Aβ deposits in the brain vasculature resulting in a disruption of the angioarchitecture. Capillaries are a critical site of Aβ pathology in CAA type 1 and become dysfunctional during disease progression. Here, applying an advanced protocol for the isolation of parenchymal microvessels from post-mortem brain tissue combined with liquid chromatography tandem mass spectrometry (LC-MS/MS), we determined the proteomes of CAA type 1 cases (n = 12) including a patient with hereditary cerebral hemorrhage with amyloidosis-Dutch type (HCHWA-D), and of AD cases without microvascular amyloid pathology (n = 13) in comparison to neurologically healthy controls (n = 12).
