Examining the Characteristics of Episodic Memory using Event-related Potentials in Patients with Alzheimer's Disease
Department of Neurology, Vanderbilt University
The methodology for collecting high-density event-related potential data while patients with Alzheimer's disease perform a recognition memory task is reviewed. This protocol will include subject preparation, quality assurance, data acquisition, and data analysis.
Detection of Neuritic Plaques in Alzheimer's Disease Mouse Model
Department of Neuroscience, The University of British Columbia
One of the pathological characteristics of AD is the formation of Amyloid β protein positive neuritic plaques. In this protocol we describe two methods to detect neuritic plaques in transgenic AD model mice: immunohistochemical detection using the ABC and DAB method and fluorescent detection using thioflavin S staining method.
Assaying β-amyloid Toxicity using a Transgenic C. elegans Model
1Institute for Behavioral Genetics, University of Colorado, 2Integrative Physiology, University of Colorado
The intensely studied nematode worm Caenorhabditis elegans can be transgenically engineered to express the human β-amyloid peptide (Aβ). Induced expression of Aβ in C. elegans muscle leads to a rapid, reproducible paralysis phenotype that can be used to monitor treatments that modulate Aβ toxicity.
A Technique for Serial Collection of Cerebrospinal Fluid from the Cisterna Magna in Mouse
Department of Pathology, Columbia University
Transgenic (Tg) mouse models of AD provide an excellent opportunity to investigate how and why Aβ or tau levels in CSF change as the disease progresses in human patients. Here, we demonstrate a refined cisterna magna puncture technique for serial CSF sampling from the mouse.
SDS-PAGE/Immunoblot Detection of Aβ Multimers in Human Cortical Tissue Homogenates using Antigen-Epitope Retrieval
1Yerkes National Primate Research Center, Emory University, 2Department of Neurology, Institute of Clinical Medicine, Tsukuba University, 3Department of Pathology, New York University School of Medicine, 4Department of Neurology, Emory University
We describe a technique for the preparation of clarified human cortical homogenates, protein separation by SDS-PAGE, antigen retrieval and immunoblotting with an antibody to the Aβ peptide. Using this protocol, we consistently detect monomeric and multimeric Aβ in cortical tissue from humans with Alzheimer's pathology.
Preparation of Acute Hippocampal Slices from Rats and Transgenic Mice for the Study of Synaptic Alterations during Aging and Amyloid Pathology
1Graduate Center for Gerontology, University of Kentucky College of Public Health, 2Department of Molecular and Biomedical Pharmacology, University of Kentucky College of Medicine, 3Sanders-Brown Center on Aging, University of Kentucky College of Medicine
This article outlines procedures for preparing hippocampal slices from rats and transgenic mice for the study of synaptic alterations associated with brain aging and age-related neurodegenerative diseases, such as Alzheimer’s disease.
Basics of Multivariate Analysis in Neuroimaging Data
Department of Neurology, Columbia University
The current article describes the basics of multivariate analysis and contrasts it to the more commonly used voxel-wise univariate analysis. Both types of analysis are applied to a clinical-neuroscience data set. Supplementary split-half simulations show better replication of the multivariate results in independent data sets.
Selection of Aptamers for Amyloid β-Protein, the Causative Agent of Alzheimer's Disease
1Department of Neurology, David Geffen School of Medicine, 2Molecular Biology Institute, University of California, Los Angeles, 3Brain Research Institute, University of California, Los Angeles
Aptamers are short ribo-/deoxyribo-oligonucleotides selected by in-vitro evolution methods based on affinity for a specific target. Aptamers are molecular recognition tools with versatile therapeutic, diagnostic, and research applications. We demonstrate methods for selection of aptamers for amyloid β-protein, the causative agent of Alzheimer's disease.
Morris Water Maze Test for Learning and Memory Deficits in Alzheimer's Disease Model Mice
Department of Psychiatry, Brain Research Center, University of British Columbia
The Morris Water Maze is a behavioral task to test hippocampal-dependent learning and memory. It has been widely used in the study of neurobiology, neuropharmacology and neurocognitive disorders in rodent models.
