    Live calcium and mitochondrial imaging in the enteric nervous system of Parkinson patients and controls

    An-Sofie Desmet et al.
    In contrast to previous post-mortem or fixed tissue histochemical reports, live calcium and mitochondrial imaging data suggest that the enteric nervous system is not generally affected in Parkinson's disease patients.

    Inhibition of synucleinopathic seeding by rationally designed inhibitors

    Smriti Sangwan et al.
    Inhibitors of seeded propagation of alpha-synuclein may be developed into diagnostics and therapeutics for Parkinson's disease.

    Depleting Trim28 in adult mice is well tolerated and reduces levels of α-synuclein and tau

    Maxime WC Rousseaux et al.
    Loss of a developmentally essential gene in adulthood is tolerated in mice, thus offering potential therapeutic options for Alzheimer's and Parkinson's disease.

    Subthalamic, not striatal, activity correlates with basal ganglia downstream activity in normal and parkinsonian monkeys

    Marc Deffains et al.
    The spiking activity of the subthalamic nucleus, rather than the activity of striatal projection neurons, orchestrates basal ganglia downstream activity and output commands in health and Parkinson’s disease.

    Mfn2 ubiquitination by PINK1/parkin gates the p97-dependent release of ER from mitochondria to drive mitophagy

    Gian-Luca McLelland et al.
    A crucial step during the mitophagy cascade involves the disassembly of connections between mitochondria and the endoplasmic reticulum via the retrotranslocation of Mfn2 tethering complexes by the Parkinson's disease genes PARKIN and PINK1, as well as the ATPase VCP/p97.

    MUL1 acts in parallel to the PINK1/parkin pathway in regulating mitofusin and compensates for loss of PINK1/parkin

    Jina Yun et al.
    By reducing mitochondrial fusion, MUL1 compensates for the mutations in PINK1 or parkin that underlie certain cases of Parkinson's disease.

    Cryo-EM structure of alpha-synuclein fibrils

    Ricardo Guerrero-Ferreira et al.
    The alpha-synuclein fibril structure reported here buries residues 50-57 at the interface between its two protofilaments, suggesting that familial Parkinson's disease associated mutations in these residues lead to a structure not compatible with the one presented here.

    Structural basis for ion selectivity in TMEM175 K+ channels

    Janine D Brunner et al.
    Structural and functional analysis of a recently discovered non-canonical potassium channel family reveals a unique selectivity filter that is exposed to permeating ions only in the conductive state.

    Movement-related coupling of human subthalamic nucleus spikes to cortical gamma

    Petra Fischer et al.
    When coupling between STN spikes and cortical gamma oscillations was strong, subsequent movement was initiated earlier, independent of changes in mean firing rates, demonstrating the importance of relative spike timing.

    Initial elevations in glutamate and dopamine neurotransmission decline with age, as does exploratory behavior, in LRRK2 G2019S knock-in mice

    Mattia Volta et al.
    LRRK2 G2019S knock-in mice are a genetically faithful model that recapitulates the slow disease progression of familial PD, with initial alterations to behaviour and neurotransmission providing early pathophysiological targets for neuroprotective interventions.
