    Measuring Breathing Patterns in Mice Using Whole-body Plethysmography
    [Abstract] Respiratory dysfunction is among the main cause of severe and fatal pathologies worldwide. The use of effective experimental models and methodologies for the study of the pulmonary pathophysiology is necessary to prevent, control and cure these diseases. Plethysmography, a technique for the assessment of lung function, has been widely applied in ...
    Integration of Human Induced Pluripotent Stem Cell (hiPSC)-Derived Neurons into Rat Brain
    Authors:  Xiling Yin, Ted M. Dawson and Valina L. Dawson, date: 09/05/2020, view: 602, Q&A: 0
    [Abstract] Human neuron transplantation offers novel opportunities for modeling human neurologic diseases and potentially replacement therapies. However, the complex structure of the human cerebral cortex, which is organized in six layers with tightly interconnected excitatory and inhibitory neuronal networks, presents significant challenges for in vivo ...
    Karyopherin-β2 Inhibits and Reverses Aggregation and Liquid-liquid Phase Separation of the ALS/FTD-Associated Protein FUS
    Authors:  Emma Robinson, James Shorter and Lin Guo, date: 08/20/2020, view: 753, Q&A: 0
    [Abstract] The study of RNA-binding proteins (RBP) offers insight into the mechanisms of pathologic protein aggregation in neurodegenerative diseases. We developed a protocol for purifying an RBP FUS and a nuclear import receptor (NIR) Kapβ2 and testing the ability of Kapβ2 to mitigate FUS aggregation and liquid-liquid phase separation.
    Co-culture of Murine Neurons Using a Microfluidic Device for The Study of Tau Misfolding Propagation
    [Abstract] The deposition of misfolded, aggregated tau protein is a hallmark of several neurodegenerative diseases, collectively termed “tauopathies”. Tau pathology spreads throughout the brain along connected pathways in a prion-like manner. The process of tau pathology propagation across circuits is a focus of intense research and has been investigated in ...
    In vivo Blood-brain Barrier Permeability Assays Using Clostridium perfringens Epsilon Toxin
    Authors:  Michael R. Mazzucco, Timothy Vartanian and Jennifer R. Linden, date: 08/05/2020, view: 489, Q&A: 0
    [Abstract] In order for the brain to function properly, a carefully orchestrated homeostasis must be maintained. To help regulate this delicate balance, the brain has developed a highly selective blood-brain barrier (BBB). Under normal conditions, the BBB excludes harmful blood-borne material from the brain parenchyma. However, numerous neuropathological ...
    Calcein Release Assay to Measure Membrane Permeabilization by Recombinant Alpha-Synuclein
    Authors:  Sayan Dutta, Ben G. Watson, Seema Mattoo and Jean-Christophe Rochet, date: 07/20/2020, view: 451, Q&A: 0
    [Abstract] Lipid membranes are involved in regulating biochemical and biological processes and in modulating the selective permeability of cells, organelles, and vesicles. Membrane composition, charge, curvature, and fluidity all have concerted effects on cellular signaling and homeostasis. The ability to prepare artificial lipid assemblies that mimic ...
    The Discrete Paired-trial Variable-delay T-maze Task to Assess Working Memory in Mice
    Authors:  Gian Marco Leggio, Sebastiano Alfio Torrisi and Francesco Papaleo, date: 07/05/2020, view: 584, Q&A: 0
    [Abstract] Working memory abnormalities involving the prefrontal cortex (PFC) dramatically contribute to poor functional outcomes in patients with schizophrenia and still represent an unmet therapeutic need. Studies in rodents might provide essential tools to understand the mechanisms underlying PFC-dependent working memory dysfunctions, as well as precious ...
    Quantitative Nucleocytoplasmic Transport Assays in Cellular Models of Neurodegeneration
    [Abstract] Nucleocytoplasmic transport deficits are suggested to play a role in neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). Given the importance and complexity of this process, understanding when these aberrations occur and which pathways are involved is of great importance. Here, we make use of CRISPR-Cas9 technology to ...
    Enriched Environment Procedures for Rodents: Creating a Standardized Protocol for Diverse Enrichment to Improve Consistency across Research Studies
    Authors:  Bruce C. Harland and John C. Dalrymple-Alford, date: 06/05/2020, view: 556, Q&A: 0
    [Abstract] Exposure to environmental enrichment has beneficial effects on learning and memory, diverse neurobiological effects, and promotes recovery of function after brain injury. The effect of enrichment is produced by a combination of increased social interaction, physical activity, spatial complexity, and novelty. Procedures in the literature have, ...
    Generation, Analyzing and in-vivo Drug Treatment of Drosophila Models with IBMPFD
    Authors:  Ting Zhang, Bruce A. Hay and Ming Guo, date: 05/20/2020, view: 905, Q&A: 0
    [Abstract] Missense mutations of p97/cdc48/Valosin-containing protein (VCP) cause inclusion body myopathy, Paget disease with frontotemporal dementia (IBMPFD) and other neurodegenerative diseases. The pathological mechanism of IBMPFD is not clear and there is no treatment. We generated Drosophila models of IBMPFD in adult flight muscle in ...
