    Pathogenic Tau–Induced Transposable Element–Derived dsRNA Drives Neuroinflammation

    Researchers found that dsRNA and dsRNA sensing machinery were elevated in astrocytes of postmortem brain tissue from patients with Alzheimer’s disease, progressive supranuclear palsy, and in brains of tau transgenic mice.

    The CDK Inhibitor AT7519 Inhibits Human Glioblastoma Cell Growth by Inducing Apoptosis, Pyroptosis and Cell Cycle Arrest

    Scientists revealed that AT7519 induced apoptosis and pyroptosis, and exhibited antitumor activity in intracranial and subcutaneous xenografted nude mice, indicating that AT7519 represented a potentially effective small molecule targeted drug for the treatment of glioblastoma.

    Hesperidin Methylchalcone (HMC) Hinders Amyloid-β Induced Alzheimer’s Disease by Attenuating Cholinesterase Activity, Macromolecular Damages, Oxidative Stress and Apoptosis via Regulating NF-κB and Nrf2/HO-1 Pathways

    The protective effect of hesperidin methylchalcone was evaluated through Alzheimer’s disease models of Neuro-2a cells and Wistar rats. The in vitro results showed that HMC possessed a significant ability to inhibit the acetylcholinesterase enzyme and exhibited anti-aggregation and disaggregation properties.

    TREM2-Dependent Microglial Function Is Essential for Remyelination and Subsequent Neuroprotection

    Using a focal demyelination model in the brain, investigators demonstrated that demyelination was persistent in triggering receptor expressed on myeloid cells 2 (TREM2) in knockout mice, lasting more than 6 weeks after lysolecithin injection, and resulted in substantial neurodegeneration.
