    Alpha-Synuclein knock-out mouse brain shows significant dysregulation of c-Fos expression

    M. Overhoff, J. Canet-Pons, D. Meierhofer, S. Gispert, G. Auburger (Frankfurt am Main, Germany)

    Objective: We aimed to understand the physiological function of alpha-synuclein (SNCA) for neuronal projections within the brain, particularly its effects on entire pathways and on…
