    Rescuing alpha-synuclein toxicity through neuron-specific enhancement of autophagy

    J. Chua, M. Farah, S. Tewari, A. Parvataneni, V. Dawson, T. Dawson (Baltimore, USA)

    Objective: In the present study, we aim to counteract regulatory and transcriptional modifiers of autophagy to enhance neuroprotective proteostasis and rescue alpha-synuclein (asyn) toxicity in…

    A juvenile onset Sandhoff disease case caused by hemizygous mutations of HEXB

    JH. Yin (Beijing, China)

    Objective: Sandhoff disease (SD) is a rare neurological disease with high clinical heterogeneity. SD in juvenile form is much rarer and it is often misdiagnosed…
