    Hsp40s play complementary roles in the prevention of tau amyloid formation

    Rose Irwin et al.
    Chaperones from different families and classes synergistically target different stages of tau aggregation, thus preventing pathological amyloid formation.

    The amyloid precursor protein is a conserved Wnt receptor

    Tengyuan Liu et al.
    The amyloid precursor protein known for its role in causing familial Alzheimer's disease directly interacts with secreted proteins, called Wnts, known for their key roles in brain development and homeostasis, suggesting the two processes may be directly linked.

    Subventricular zone/white matter microglia reconstitute the empty adult microglial niche in a dynamic wave

    Lindsay A Hohsfield et al.
    In an empty microglial niche, repopulating microglia arise from subventricular zone and white matter-associated areas without contributions from the bone marrow to fill the mouse brain via a spreading wave.

    The severity of microstrokes depends on local vascular topology and baseline perfusion

    Franca Schmid et al.
    The number of inflows and outflows at the occluded capillary governs the local flow reduction, and the different topological configurations are probably designed for distinct functional tasks.

    Loss of Mir146b with aging contributes to inflammation and mitochondrial dysfunction in thioglycollate-elicited peritoneal macrophages

    Andrea Santeford et al.
    MicroRNA-146b regulates aging, activation, and mitochodrial function in thioglycollate-elicited peritoneal macrophages.

    The mitochondrial permeability transition pore activates the mitochondrial unfolded protein response and promotes aging

    Suzanne Angeli et al.
    Loss of the F-ATP synthase c-subunit inhibits a pathological mitochondrial permeability transition pore that is coupled to a maladaptive mitochondrial unfolded protein response while also extending lifespan.

    Neuronal timescales are functionally dynamic and shaped by cortical microarchitecture

    Richard Gao et al.
    Invasive electrophysiological recording measures neuronal transmembrane current timescales across human cortex, which lengthens from sensory to association regions, follows variations in ion channel expressions, and alters with behavior and aging.

    Temporal pattern and synergy influence activity of ERK signaling pathways during L-LTP induction

    Nadiatou T Miningou Zobon et al.
    ERK activation during induction of long-term synaptic plasticity is enhanced by synergistic interactions among signaling pathways mediated by the synaptically located GTPase-activating protein, and each pathway contributes to different ERK temporal dynamics.
