  1. Neurodegenerative processes of ageing and disease nPad

  2. Aims of the consortium • Identify key genes and proteins involved in triggering neurodegeneration in vivo. • Examine contribution of neuronal, synaptic and glial dysfunction to neurodegeneration. • Assess biomarkers of cognition and behaviour capable of tracking neurodegeneration. • Study impact of stress, infection and age on neurodegenerative processes. • Identify common and distinct molecular mechanisms underlying neurodegeneration. • Develop strategies for blocking neurodegenerative processes.

  4. The Expertise • Identifying and analysing disorders of the brain, spinal cord, eye, peripheral nervous system and muscle using a range of morphological, molecular, behavioural and functional approaches. • The Tools • Microscopy (including confocal and electron microscopy), • Neurophysiology (including in vitro electrophysiology and synaptic physiology), Molecular biology (including proteomic and gene expression screens), mouse behavioural models of learning and memory • Additional Resources • Access to unique human ageing cohorts • Access to banks of human tissues from normal individuals and patients with a wide variety of disorders • Current strategic award bid to Wellcome for a major centre for Comparative Pathology

  5. Rationale for prioritising genes • Candidate genes fromstudies of human patient cohorts and mouse models of neurodegenerative disease to define targets for knockouts. • Examination of publicly available gene expression data sets to discover genes that are expressed in neurons and are important in synaptic function. • Evidence that chosen genes may be important in neurodegenerative disease from human studies or mouse models, in particular those with an identified role at the early stages of disease.

  12. Our approach • We expect the knockouts of targets described here will alter the early part of the process of neurodegeneration • Our phenotypic analysis will be designed to use the full range of expertise within the consortium to analyse neurodegenerative progression through: • studies on behavioural phenotype induced by the knockout; • examining the influence of the knockout on acute or chronic neurodegenerative process; • analysing phenotypes arising from ageing the knockout mice with and without well characterised stressful interventions (model systems).
