    Structural basis for the prion-like MAVS filaments in antiviral innate immunity

    Hui Xu et al.
    Mitochondrial anti-viral signaling proteins form three-stranded helical filaments in launching innate immune responses against RNA viruses.

    Spatial quality control bypasses cell-based limitations on proteostasis to promote prion curing

    Courtney L Klaips et al.
    Cell division imposes a limit on proteostasis capacity by reducing chaperone accumulation, but chaperone-substrate interactions reverse these events to allow clearance of even chronically misfolded protein amyloids.

    Monitoring site-specific conformational changes in real-time reveals a misfolding mechanism of the prion protein

    Ishita Sengupta, Jayant Udgaonkar
    Multi-site FRET measurements of moPrP oligomerization at low pH indicate that major conformational changes take place as monomers reversibly transform into large oligomers, which subsequently disassemble reversibly into small oligomers.

    Development of schemas revealed by prior experience and NMDA receptor knock-out

    George Dragoi, Susumu Tonegawa
    Novel spatial representations by hippocampal cellular assemblies develop on the framework of preconfigured hippocampal networks whose homeostatic synaptic reorganization is accelerated by prior experience and CA3 NMDAR-dependent plasticity.

    How prior preferences determine decision-making frames and biases in the human brain

    Alizée Lopez-Persem et al.
    Model-based analyses of choice behavior and fMRI activity revealed that prior preferences generate default policies, which frame the decision value signal encoded in the vmPFC, and shift vmPFC pre-choice activity so as to induce a decision bias toward default options.

    Light-based tuning of ligand half-life supports kinetic proofreading model of T cell signaling

    Doug K Tischer, Orion David Weiner
    Direct control of ligand binding half-life with light shows that lifetime strongly affects T cell signaling.

    Neural clocks and Neuropeptide F/Y regulate circadian gene expression in a peripheral metabolic tissue

    Renske Erion et al.
    Neuropeptide F/Y from neurons drives rhythmic expression of detoxification-related genes in a peripheral metabolic tissue in flies and mice.

    Functional limb muscle innervation prior to cholinergic transmitter specification during early metamorphosis in Xenopus

    Francois M Lambert et al.
    Molecular labeling, electrophysiology and calcium imaging have revealed a novel switching of neurotransmitter at the frog neuromuscular junction where motoneurons transiently release glutamate before acetylcholine at synapses on developing hindlimb muscles at the onset of metamorphosis.

    Evaluating mesenchymal stem cell therapy for sepsis with preclinical meta-analyses prior to initiating a first-in-human trial

    Manoj M Lalu et al.
    A rigorous and transparent evaluation of mesenchymal stem cell therapy for sepsis suggests it may be efficacious, although the strength of these findings is tempered by threats to validity in the studies that were included.
