    Presenilin mutations deregulate mitochondrial Ca2+ homeostasis and metabolic activity causing neurodegeneration in Caenorhabditis elegans

    Shaarika Sarasija et al.
    In C. elegans, presenilin functions, independent of its gamma-secretase proteolytic activity, to regulate mitochondrial metabolism by controlling ER-mitochondrial calcium transfer and, even in the absence of Abeta signaling, loss of this activity leads to neurodegeneration.

    Parkinson’s Disease: Linking mitochondria to the immune response

    Rebecca L Wallings et al.

    Alleviation of neuronal energy deficiency by mTOR inhibition as a treatment for mitochondria-related neurodegeneration

    Xinde Zheng et al.
    Rapamycin treatment inhibits mTOR activity and preserves ATP levels in neurons derived from induced pluripotent stem cells from a maternally inherited Leigh syndrome patient.

    Elevating acetyl-CoA levels reduces aspects of brain aging

    Antonio Currais et al.
    A novel neuroprotective pathway that enhances acetyl-CoA metabolism via inhibition of acetyl-CoA carboxylase 1 may prevent the contribution of the aging process in the brain to Alzheimer's disease.

    Deficiency of parkin and PINK1 impairs age-dependent mitophagy in Drosophila

    Tom Cornelissen et al.
    Mitophagy occurs in Drosophila flight muscle and dopaminergic neurons in vivo and increases with aging in a PINK1/parkin-dependent fashion.

    Impaired lysosomal acidification triggers iron deficiency and inflammation in vivo

    King Faisal Yambire et al.
    Impaired lysosomal acidification results in retention of iron inside lysosomes, triggering functional iron deficiency, dysfunctional mitochondria (especially mtDNA loss), and inflammation in vivo in a mouse model of lysosomal disease.

    Early dysfunction and progressive degeneration of the subthalamic nucleus in mouse models of Huntington's disease

    Jeremy F Atherton et al.
    In mouse models of Huntington's disease, the subthalamic nucleus, which suppresses movements, also exhibits impaired glutamate homeostasis, NMDA receptor-dependent mitochondrial oxidant stress, firing disruption, and 30% neuronal loss.

    Chemoptogenetic ablation of neuronal mitochondria in vivo with spatiotemporal precision and controllable severity

    Wenting Xie et al.
    Novel transgenic zebrafish lines allow selective ablation of neuronal mitochondria by far red light, providing a powerful tool for investigating mitochondrial homeostasis in neurons and mitochondrial mechanisms in neurological disease.
