    Hippocampal Unicellular Recordings and Hippocampal-dependent Innate Behaviors in an Adolescent Mouse Model of Alzheimer’s disease
    [Abstract] Transgenic mice have been used to make valuable contributions to the field of neuroscience and model neurological diseases. The simultaneous functional analysis of hippocampal cell activity combined with hippocampal dependent innate task evaluations provides a reliable experimental approach to detect fine changes during early phases of ...
    Induction of Temporal Lobe Epilepsy in Mice with Pilocarpine
    Authors:  Muhammad Nauman Arshad and Janice R Naegele, date: 02/20/2020, view: 19, Q&A: 0
    [Abstract] In the pilocarpine model of temporal lobe epilepsy (TLE) in rodents, systemic injections of pilocarpine induce continuous, prolonged limbic seizures, a condition termed “Status Epilepticus” (SE). With appropriate doses, many inbred strains of mice show behavioral seizures within an hour after pilocarpine is injected. With the behavioral scoring ...
    Studying Protein Aggregation in the Context of Liquid-liquid Phase Separation Using Fluorescence and Atomic Force Microscopy, Fluorescence and Turbidity Assays, and FRAP
    Authors:  W. Michael Babinchak and Witold K. Surewicz, date: 01/20/2020, view: 456, Q&A: 0
    [Abstract] Liquid-liquid phase separation (LLPS) underlies the physiological assembly of many membrane-less organelles throughout the cell. However, dysregulation of LLPS may mediate the formation of pathological aggregates associated with neurodegenerative diseases. Here, we present complementary experimental approaches to study protein aggregation within ...
    A Single Test to Study Social Behavior and Repetitive Self-grooming in Mice
    Authors:  Niraj V. Lawande, Ammar L. Ujjainwala and Catherine A. Christian, date: 01/20/2020, view: 379, Q&A: 0
    [Abstract] The ability to recognize and interact with members of the same species is essential for social communication. Investigating the neural substrates of social interest and recognition may offer insights into the behavioral differences present in disorders affecting social behavior. Assays used to study social interest in rodents include the 3-chamber ...
    The Mouse Gambling Task: Assessing Individual Decision-making Strategies in Mice
    Authors:  Elsa Pittaras, Arnaud Rabat and Sylvie Granon, date: 01/05/2020, view: 313, Q&A: 0
    [Abstract] Decision-making is a complex cognitive process which consists of choosing one option among several alternatives. In humans, this process is featured in the Iowa gambling task (IGT), a decision-making task that mimics real life situations by reproducing uncertain conditions based on probabilistic rewards or penalties (see Background). Several ...
    Myelin Oligodendrocyte Glycoprotein 35-55 (MOG 35-55)-induced Experimental Autoimmune Encephalomyelitis: A Model of Chronic Multiple Sclerosis
    Authors:  Sakie Miyamura, Nagisa Matsuo, Kazuki Nagayasu, Hisashi Shirakawa and Shuji Kaneko, date: 12/20/2019, view: 512, Q&A: 0
    [Abstract] Multiple sclerosis (MS) is the common demyelinating disease of human central nervous system. Among mouse models available to study MS, including the cuprizone application and lysolecithin-injection models, experimental autoimmune encephalomyelitis (EAE) model is widely used so that chronic EAE model of C57BL/6J can reflect the autoimmune ...
    Semi-automated Model to Accurately Counting Sympathetic Nervous Fibers
    [Abstract] In recent years, the role of sympathetic nervous fibers in chronic inflammation has become increasingly evident. At the onset of inflammation, sympathetic activity is increased in the affected tissue. However, sympathetic fibers are largely absent from chronically inflamed tissues. Apparently, there is a very dynamic relationship between ...
    Mitochondrial Respiratory Measurements in Patient-derived Fibroblasts
    Authors:  Prashant Mishra, Ting Zhang, Ming Guo and David Chan, date: 12/05/2019, view: 459, Q&A: 0
    [Abstract] Mitochondrial dysfunction is associated with a number of human diseases. As an example, we recently established in vivo Drosophila models of IBMPFD (Inclusion body myopathy, Paget disease, and frontotemporal dementia), and uncovered that human disease mutations of the p97/VCP (Valosin Containing Protein) gene behave as ...
    Intra-arterial Drug Delivery to the Ischemic Brain in Rat Middle Cerebral Artery Occlusion Model
    [Abstract] Rat transient middle cerebral artery occlusion (tMCAO) model is one of the most commonly used animal models in ischemic stroke studies. In the model, increasing safety and efficacy of therapeutic agent administration, such as stem cells and drugs directly to the ischemic brain using the internal carotid artery (ICA) is essential, because using the ...
    SarkoSpin: A Technique for Biochemical Isolation and Characterization of Pathological TDP-43 Aggregates
    Authors:  Manuela Pérez-Berlanga, Florent Laferrière and Magdalini Polymenidou, date: 11/20/2019, view: 908, 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 ...
