    Studying the Role of Microglia in Neurodegeneration and Axonal Regeneration in the Murine Visual System
    Authors:  Alexander M Hilla and Dietmar Fischer, date: 08/20/2018, view: 43, Q&A: 0
    [Abstract] Microglia reside in the central nervous system (CNS) and are involved in the maintenance of the physiologic state. They constantly survey their environment for pathologic alterations associated with injury or diseases. For decades, researchers have investigated the role of microglia under different pathologic conditions, using approaches aiming to ...
    Trace Fear Conditioning: Procedure for Assessing Complex Hippocampal Function in Mice
    [Abstract] The trace fear conditioning protocol is designed to measure hippocampal function in mice. The protocol includes a neutral conditioned stimulus (tone) and an aversive unconditioned stimulus (shock), separated in time by a trace interval. The trace interval between the tone and the shock critically involves the hippocampus and could be used to ...
    Image-Based Analysis of Mitochondrial Area and Counting from Adult Mouse Dopaminergic Neurites
    Authors:  Nadee Nissanka, Carlos T Moraes and Mlena Pinto, date: 08/20/2018, view: 26, Q&A: 0
    [Abstract] Mitochondria form dynamic cytoplasmic networks which undergo morphological changes in order to adapt to cellular stresses and signals. These changes can include alterations in size and number within a given cell. Analysis of the whole network can be a useful metric to assess overall mitochondrial health, particularly in neurons, which are highly ...
    Isolation of LYVE-1+ Endothelial Cells from Mouse Embryos
    Author:  Patrick Crosswhite, date: 08/05/2018, view: 118, Q&A: 0
    [Abstract] Lymphatic vessel endothelial hyaluronan receptor 1, or LYVE-1, is a type 1 integral membrane glycoprotein expressed by lymphatic endothelial cells (LECs). LYVE-1 is commonly used as a biological marker to visually distinguish developing lymphatic vessels from blood endothelial cells (arteries or veins). As our understanding of lymphatic biology is ...
    Quantitative Electron Microscopic Assay Using Random Sampling from Single Sections to Test Plastic Synaptic Changes in Hippocampus
    Authors:  G. Mark Marcello, Lilla E. Szabó, Peter Sotonyi and Bence Rácz, date: 08/05/2018, view: 135, Q&A: 0
    [Abstract] Studies over several decades on the organization of the CA1 hippocampus–a particularly favorable model for learning, memory and certain forms of cognition–have shown that the synaptic network in this brain region is plastic (Fortin et al., 2012). Recent evidence suggests that a number of environmental and endogenous stimuli may have a ...
    Measurement of TLR4 and CD14 Receptor Endocytosis Using Flow Cytometry
    Authors:  Michael S. Schappe and Bimal N. Desai, date: 07/20/2018, view: 501, Q&A: 0
    [Abstract] After recognizing extracellular bacterial lipopolysaccharide (LPS), the toll-like receptor 4 (TLR4)-CD14 signaling complex initiates two distinct signaling pathways–one from the plasma membrane and the other from the signaling endosomes (Kagan et al., 2008). Understanding the early stages of TLR4 signal transduction therefore requires a ...
    Embryonic Intravitreous Injection in Mouse
    Authors:  Liyuan Cui, Yupu Diao and Jiayi Zhang, date: 07/20/2018, view: 180, Q&A: 0
    [Abstract] Axons of retinal ganglion cells (RGCs) relay visual information from the retina to lateral geniculate nucleus (LGN) and superior colliculus (SC), which are two major image-forming visual nuclei. Wiring of these retinal projections completes before vision begins. However, there are few studies on retinal axons at embryonic stage due to technical ...
    Evaluating Working Memory on a T-maze in Male Rats
    Authors:  Ahmed M. Hussein, Mekite Bezu and Volker Korz, date: 07/20/2018, view: 333, Q&A: 0
    [Abstract] Working memory is short-term memory, so temporal improvement does not reflect the consolidation of a memory trace, rather the functionality of the underlying neuronal circuits and molecular signaling cascades. The administration of drugs–either one-time or through daily injection–can elucidate the underlying mechanisms. The T-maze is especially ...
    Assessment of Uptake and Biodistribution of Radiolabeled Cholesterol in Mice Using Gavaged Recombinant Triglyceride-rich Lipoprotein Particles (rTRL)
    Authors:  Anna Worthmann, Clara John and Joerg Heeren, date: 07/05/2018, view: 329, Q&A: 0
    [Abstract] The here described method can be used to estimate the uptake of orally provided cholesterol in mice. Briefly, mice are gavaged with radiolabeled cholesterol and 4 h later, organ distribution of the radiolabel is determined by liquid scintillation counting. The method has been applied successfully to determine dietary cholesterol handling of mice ...
    Preparation of Cerebellum Granule Neurons from Mouse or Rat Pups and Evaluation of Clostridial Neurotoxin Activity and Their Inhibitors by Western Blot and Immunohistochemistry
    Authors:  Domenico Azarnia Tehran and Marco Pirazzini, date: 07/05/2018, view: 440, Q&A: 0
    [Abstract] Cerebellar Granule Neurons (CGN) from post-natal rodents have been widely used as a model to study neuronal development, physiology and pathology. CGN cultured in vitro maintain the same features displayed in vivo by mature cerebellar granule cells, including the development of a dense neuritic network, neuronal activity, ...
