    The Cerebellum Directly Modulates the Substantia Nigra Dopaminergic Activity

    The authors showed, in mice, that cerebellar projections to the substantia nigra pars compacta (SNc) form monosynaptic glutamatergic synapses with dopaminergic and non-dopaminergic neurons in the SNc.

    Prolonged Myelin Deficits Contribute to Neuron Loss and Functional Impairments after Ischemic Stroke

    Scientists reported numerous denuded axons in the lesion of human brain sections with ischemic stroke, accompanied by decreased neuron density, suggesting neuron loss correlates with myelin deficits in the stroke lesion.

    Abstract

    Targeted Degradation of SNCA/α-Synuclein Aggregates in Neurodegeneration Using the AUTOTAC Chemical Platform

    Researchers employed autophagy-targeting chimera (AUTOTAC) to synthesize ATC161, a chimeric compound that adopts Anle138b as target-binding ligand for SNCA aggregates.

    Abstract

    Astrocytic TIMP-1 Regulates Production of Anastellin, an Inhibitor of Oligodendrocyte Differentiation and FTY720 Responses

    The authors performed an unbiased proteomic analysis and identified a fibronectin-derived peptide called Anastellin that was unique to the tissue inhibitor of metalloproteinase-1 (TIMP1) knockout astrocyte secretome.

    SRF-Deficient Astrocytes Provide Neuroprotection in Mouse Models of Excitotoxicity and Neurodegeneration

    Scientists reported that conditional deletion of serum response factor (SRF) in adult astrocytes caused reactive-like hypertrophic astrocytes throughout the mouse brain.

    Abstract

    Enhanced Innate Responses in Microglia Derived from Retinoblastoma Patient-Specific iPSCs

    Microglia were successfully differentiated from retinoblastoma patient-derived human induced pluripotent stem cells and human embryonic stem cells, and researchers investigated the function of RB1 in microglia by live imaging phagocytosis assay, immunofluorescence, RNA-seq, qRT-PCR, ELISA, and more.

    Abstract

    Desloratadine Alleviates ALS-Like Pathology in hSOD1G93A Mice via Targeting 5HTR2A on Activated Spinal Astrocytes

    Investigators evaluated the therapeutic effects of desloratadine, a selective 5HTR2A antagonist, in human SOD1G93A (hSOD1G93A) ALS model mice.

    Glial Cells React to Closed Head Injury in a Distinct and Spatiotemporally Orchestrated Manner

    Scientists analyzed the reaction of glial cells in a highly translational but variable closed-head injury model and were able to correlate the severity of the trauma to the degree of glial response.
