    TOP STORY

    A Brainstem–Hypothalamus Neuronal Circuit Reduces Feeding upon Heat Exposure

    Scientists showed that tanycytes were activated upon acute thermal challenge and were necessary to reduce food intake afterwards.

    Selection of Experience for Memory by Hippocampal Sharp Wave Ripples

    By combining large-scale neural recordings in mice with dimensionality reduction techniques, investigators observed that successive maze traversals were tracked by continuously drifting populations of neurons, providing neuronal signatures of both places visited and events encountered.

    A Cell Fate Decision Map Reveals Abundant Direct Neurogenesis Bypassing Intermediate Progenitors in the Human Developing Neocortex

    Scientists developed a semi-automated live/fixed correlative imaging method to map basal radial glial cell division modes in early fetal tissue and cerebral organoids.

    Interaction of Acetylcholine and Oxytocin Neuromodulation in the Hippocampus

    Researchers investigated the interaction of acetylcholine and oxytocin at slow and fast timescales during various brain states.

    Abstract

    Intron Detention Tightly Regulates the Stemness/Differentiation Switch in the Adult Neurogenic Niche

    The authors showed that m6A methylation was the mechanism that released intron detention and triggered nuclear export, enabling rapid and synchronized responses.

    Restoration of Neuronal Progenitors by Partial Reprogramming in the Aged Neurogenic Niche

    Investigators used single-cell transcriptomics to systematically examine how partial reprogramming influenced the subventricular zone neurogenic niche in aged mouse brains.
    [Nature Aging]

    Abstract

    APP Antisense Oligonucleotides Reduce Aβ Aggregation and Rescue Endolysosomal Dysfunction in Alzheimer’s Disease

    Researchers found that antisense oligonucleotides targeting APP are an effective approach to reduce APP protein levels and rescue endolysosome and autophagy dysfunction in APP duplication human induced pluripotent stem cell-derived cortical neurons.

    Abstract

    The Growth Factor EPIREGULIN Promotes Basal Progenitor Cell Proliferation in the Developing Neocortex

    Scientists showed that EREG, encoding the growth factor EPIREGULIN, was expressed in the human developing neocortex and in gorilla cerebral organoids, but not in the mouse neocortex.

    Depletion of Mettl3 in Cholinergic Neurons Causes Adult-Onset Neuromuscular Degeneration

    To assess the m6A requirement in motor neurons (MNs), researchers depleted the m6A methyltransferase-like 3 (METTL3) in cells and mice. METTL3 depletion in embryonic stem cell-derived MNs had profound and selective effects on survival and neurite outgrowth.

    The Endotoxin Hypothesis of Alzheimer’s Disease

    Scientists outline the hypothesis here that lipopolysaccharide (LPS) may contribute to the pathophysiology of Alzheimer’s disease (AD) via peripheral infections or gut dysfunction elevating LPS levels in blood and brain.

    Presynaptic Perspective: Axonal Transport Defects in Neurodevelopmental Disorders

    The authors discuss presynaptic perspectives of neurodevelopmental disorders by focusing on impaired axonal transport and disturbed assembly and maintenance of presynapses.
