    Warburg-Like Metabolic Transformation Underlies Neuronal Degeneration in Sporadic Alzheimer’s Disease

    Utilizing directly converted induced neurons (iNs) from Alzheimer’s disease (AD)-patient-derived fibroblasts, the authors identified a metabolic switch to aerobic glycolysis in AD iNs.

    Lysosomal Exocytosis Releases Pathogenic α-Synuclein Species From Neurons in Synucleinopathy Models

    Scientists generated a new mouse model to specifically immunoisolate neuronal lysosomes, and established a long-term culture model where α-Synuclein aggregates were produced within neurons without the addition of exogenous fibrils.

    FMRP Modulates the Wnt Signaling Pathway in Glioblastoma

    The authors reported that reductions in Fragile X Messenger Ribonucleoprotein (FMRP) correlated with a diminished tumor growth and proliferation of human glioblastoma stem-like cells (GSCs) in vitro in a cell culture model and in vivo in mouse brain GSC xenografts.

    Human Tau Mutations in Cerebral Organoids Induce a Progressive Dyshomeostasis of Cholesterol

    Scientists found that in human cerebral organoids carrying the V337M and R406W tau mutations, the cholesterol biosynthesis pathway in astrocytes was the top upregulated gene set compared with isogenic controls by single-cell RNA sequencing.

    Neuroblastoma: When Differentiation Goes Awry

    The authors provide evidence that supports the notion that arrested neural-crest-derived progenitor cells give rise to neuroblastoma and discuss how this concept could be exploited for clinical management of the disease.

    UC San Diego Receives $1.3M from W. M. Keck Foundation to Study Origins of Dementia

    Researchers at the University of California San Diego have received a $1.3 million grant from the W. M. Keck Foundation for a project that could help scientists better understand the role misfolded tau proteins play in causing neurodegenerative diseases like dementia, which may lead to more effective drug therapies.
