    SarkoSpin: A Technique for Biochemical Isolation and Characterization of Pathological TDP-43 Aggregates
    Authors:  Pérez-Berlanga Manuela, Laferrière Florent and Polymenidou Magdalini, date: 11/20/2019, view: 198, Q&A: 0
    TDP-43 is the main aggregating protein in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Aggregated TDP-43 is resistant to diverse detergent solubilization, yet physiological ...
    Gallyas Silver Impregnation of Myelinated Nerve Fibers
    Authors:  Sabitha Joseph, Hauke B. Werner and Judith Stegmüller, date: 11/20/2019, view: 38, Q&A: 0
    In the nervous system of vertebrates, nerve impulse propagation is accelerated by the ensheathment of neuronal axons with myelin. Myelin sheaths are molecularly specialized, lipid-rich plasma membrane extensions of Schwann cells in the peripheral ...
    SarkoSpin: A Technique for Biochemical Isolation and Characterization of Pathological TDP-43 Aggregates
    Authors:  Pérez-Berlanga Manuela, Laferrière Florent and Polymenidou Magdalini, date: 11/20/2019, view: 198, Q&A: 0
    [Abstract] TDP-43 is the main aggregating protein in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). Aggregated TDP-43 is resistant to diverse detergent solubilization, yet physiological TDP-43 and other abundant proteins commonly co-purify with pathological TDP-43. This mixed isolation has ...
    Gallyas Silver Impregnation of Myelinated Nerve Fibers
    Authors:  Sabitha Joseph, Hauke B. Werner and Judith Stegmüller, date: 11/20/2019, view: 38, Q&A: 0
    [Abstract] In the nervous system of vertebrates, nerve impulse propagation is accelerated by the ensheathment of neuronal axons with myelin. Myelin sheaths are molecularly specialized, lipid-rich plasma membrane extensions of Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system (CNS). To visualize myelinated nerve ...
    Isolation and Imaging of His- and RFP-tagged Amyloid-like Proteins from Caenorhabditis elegans by TEM and SIM
    Authors:  Amberley D. Stephens, Meng Lu and Gabriele S. Kaminski Schierle, date: 11/05/2019, view: 237, Q&A: 0
    [Abstract] In our recently published paper, we highlight that during normal aging of C. elegans age-dependent aggregates of proteins form and lead to functional decline of tissues. The protocol described here details the isolation of two proteins from C. elegans in their aggregated amyloid-like form, casein kinase I isoform alpha (KIN-19) ...
    Optogenetic Food Odor Avoidance Assay
    Authors:  Jay M. Patel, Jessica Swanson and Benjamin R. Arenkiel, date: 10/20/2019, view: 283, Q&A: 0
    [Abstract] Appetite is tightly linked to the sensory experience of feeding, including the smell, taste, and sight of food. Sensory perception can affect the palatability of food, modulating appetite beyond homeostatic requirements. Hypothalamic neurons that govern feeding are responsive to sensory cues associated with food, including food odors. However, the ...
    Use of the Vsoc-maze to Study Sociability and Preference for Social Novelty in Rodents
    [Abstract] Studying social behavior in mouse models empowers the understanding of the neurobiological mechanisms involved, which are affected in neuropsychiatric disorders, allowing the evaluation of therapeutic strategies. Behavioral methods available are time-consuming and reducing the length of behavioral sessions may render more manageable experiments ...
    Intracerebral Injection of Streptozotocin to Model Alzheimer Disease in Rats
    [Abstract] Animal models have promoted meaningful contribution to science including Alzheimer’s disease (AD) research. Several animal models for AD have been used, most of them related to genetic mutations observed in familial AD. However, sporadic form of AD, also named late-onset is the most frequent form of the disease, which is multifactorial, being ...
    Antisense Oligodeoxynucleotide Perfusion Blocks Gene Expression of Synaptic Plasticity-related Proteins without Inducing Compensation in Hippocampal Slices
    [Abstract] The elucidation of the molecular mechanisms of long-term synaptic plasticity has been hindered by both the compensation that can occur after chronic loss of the core plasticity molecules and by ex vivo conditions that may not reproduce in vivo plasticity. Here we describe a novel method to rapidly suppress gene expression by ...
    ATAC-seq on Sorted Adult Mouse Neurons
    Authors:  Erin A. Clark, Yasuyuki Shima and Sacha Nelson, date: 10/05/2019, view: 438, Q&A: 0
    [Abstract] Transcription regulation is a key aspect of cellular identity established during development and maintained into adulthood. Molecular and biochemical assays that probe the genome are critical tools in exploring mechanisms of transcription regulation and cell type identity. The mammalian brain is composed of a huge diversity of cell types with ...
    Identification of Heteroreceptors Complexes and Signal Transduction Events Using Bioluminescence Resonance Energy Transfer (BRET)
    Authors:  Irene Reyes-Resina, Jasmina Jiménez, Gemma Navarro and Rafael Franco, date: 10/05/2019, view: 314, Q&A: 0
    [Abstract] Detecting protein-protein interactions by co-immunoprecipitation provided a major advancement in the immunology research field. In the G-protein-coupled receptors (GPCRs) research field, colocalization and co-immunoprecipitation were used to detect interactions, but doubts arose due to specificity of the antibodies (monoclonal in the case of ...
    An Operant Conditioning Task to Assess the Choice between Wheel Running and Palatable Food in Mice
    Authors:  Bastien Redon, Imane Hurel, Giovanni Marsicano and Francis Chaouloff, date: 10/05/2019, view: 378, Q&A: 0
    [Abstract] Wheel running, especially in the homecage, has been widely used to study the neurobiology of exercise because animal tends to use it voluntarily. However, as for each reward, its consumption (in the present case, running performance) does not specifically provide information on its incentive value, i.e., the extent to which animals are ...
