    Brain aging comprises many modes of structural and functional change with distinct genetic and biophysical associations

    Stephen M Smith et al.
    Imaging of structure and function in the brain from thousands of participants was used along with genetics and biophysical measures to study many different aspects of how the brain ages.

    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.

    Differential accumulation of storage bodies with aging defines discrete subsets of microglia in the healthy brain

    Jeremy Carlos Burns et al.
    Two novel subsets of microglia identified by their unique autofluorescence profiles differ in their subcellular organization, proteomic signatures and in their response to aging and lysosomal dysfunction.

    Retromer subunit, VPS29, regulates synaptic transmission and is required for endolysosomal function in the aging brain

    Hui Ye et al.
    Vps29 promotes retromer localization in the adult Drosophila brain, engaging Rab7 and TBC1D5, and its loss triggers age-dependent neuronal impairments in endolysosomal trafficking and synaptic transmission.

    Cortical tau deposition follows patterns of entorhinal functional connectivity in aging

    Jenna N Adams et al.
    Tau deposition in the aging brain follows patterns of functional connectivity that correspond to specific neural memory networks, and this relationship is strengthened in the presence of amyloid-β.

    Chemical modulation of transcriptionally enriched signaling pathways to optimize the conversion of fibroblasts into neurons

    Joseph Herdy et al.
    An unbiased RNAseq based strategy to identify targetable pathways and a streamlined lentiviral system provide a state of the art advance on direct fibroblast to neuron conversion.

    Attenuation of dopamine-modulated prefrontal value signals underlies probabilistic reward learning deficits in old age

    Lieke de Boer et al.
    Attenuated anticipatory activity in ventromedial prefrontal cortex is modulated by dopamine D1 receptor density in nucleus accumbens, and accounts for impaired probabilistic reward learning in older adults.

    Tau and spectraplakins promote synapse formation and maintenance through Jun kinase and neuronal trafficking

    Andre Voelzmann et al.
    A novel regulatory cascade downstream of Tau and spectraplakins ensures that synaptic proteins are delivered to axonal terminals in the developing and ageing brain, providing potential explanations for precocious synapse loss in dementias.
