Blood-brain barrier dysfunction in response to Alzheimer's disease mutations and aged serum in a tissue-engineered microvascular model

Project description:Alzheimer’s disease is a disease of neurodegeneration and aging that affects millions of Americans, and is expected to impact millions more without significant advancement in our understanding of the disease. An emerging focus in Alzheimer’s study is the role of the cerebrovasculature in the initiation, progression, and exacerbation of symptomatic disease. Disruption of the blood-brain barrier, which tightly controls any exchange between systemic circulation and brain tissue, has manifested in post-mortem and in vivo studies of late-stage Alzheimer’s disease as microbleeds, dysfunctional glucose transport, and impaired efflux of toxins; additional animal studies have indicated that some vascular dysfunction precedes neuronal degeneration in the progression of the disease. Thus, to understand the drivers and progression of Alzheimer’s disease in hopes of identifying therapeutic breakpoints, the role of blood-brain barrier dysfunction must be investigated. Here, we utilize a tissue-engineered model of the blood-brain barrier with high spatiotemporal resolution to assess its dysfunction with cell-intrinsic mutations associated with Alzheimer’s (APP(Swe) and PSEN1(M146V)) and the systemic influence of aged blood components (exposure to aged vs. young human serum).

Ultra-Processed Foods drive Intestinal Barrier permeability increasing Microvascular Disease risk

Project description:Abstract: Our intake of ultra-processed foods has dramatically increased over the past few decades in line with the prevalence of obesity and diabetes, key risk factors for microvascular diseases such as chronic kidney disease (CKD). The extent to which long-term intake of highly processed food influences CKD outcome is unclear. Here, we show in rodent models that a highly processed diet drives intestinal barrier permeability and an increased risk of CKD. Inhibition of the advanced glycation pathway, which generates Maillard reaction products within foods upon thermal processing, reversed kidney injury. Consequently, a highly processed diet leads to innate immune complement activation and local kidney inflammation via the potent proinflammatory effector molecule complement 5a (C5a). C5a receptor inhibition ameliorated albuminuria. In a mouse model of diabetes, a high resistant starch fiber diet led to a redistribution of the gut commensal consortium, prevented impaired gut barrier function and decreased the severity of kidney injury via suppression of complement. These results provide mechanistic insight into the role of highly processed foods on inflammation and chronic disease risk. One Sentence Summary: Ultra-processed diets promote chronic kidney disease

Cerebellum Alzheimer's Disease

Project description:Ion channel splice array data from cerebellum brain tissue samples collected from Alzheimer's disease patients. Temporal cortex (Alzheimer's disease affected brain tissue structure) and cerebellum (Alzheimer's disease unaffected brain tissue structure) samples from control subjects were compared to temporal cortex and cerebellum of patients with Alzheimer's disease.

Novel insights into retinal microvascular endothelial cells revealed through single cell RNA-seq analysis.

Project description:Purpose: To better characterise the population structure of primary bovine retinal microvascular endothelial cells (RMECs) based upon their individual transcriptomes. Methods: Individual RMECs were captured on the Fluidigm C1 system (Fluidigm), cDNA libraries were prepared using a Nextera XT kit and sequencing performed on a NextSeq (Illumina). Results: Application of a single cell RNA-seq analysis workflow showed that RMECs form a relatively homogeneous population in culture, with the main subgroup being proliferating cells. Expression of markers from along the arteriovenous tree suggests that most cells originate from capillaries. An in silico model of the blood retinal barrier was created, including junctional proteins not previously reported within the retinal vasculature. Numerous alternative splicing events involving exons within microvascular barrier genes were observed and in many cases individual cells expressed exclusively one isoform. Conclusions: We have optimised a workflow for single-cell transcriptomics in primary RMECs. Our results have provided fundamental insights into the genes involved in retinal microvascular barrier formation.
