Selective loss of Primary Cilia and Neurotrophic Signaling in G51D α-Synuclein Mice Highlights a Common Pathway to Parkinson’s Disease
By onG51D α-synuclein mice mimic disease symptoms, showing cilia loss in specific neurons and impaired neurotrophic signaling, contributing to disease progression. This highlights the role of ciliary dysfunction in Parkinson’s.
Elevated phosphorylated α-synuclein and phosphorylated tau in Lrrk2 p.G2019S-mutant mice following influenza A pneumonitis
By onInfluenza virus infection does not alter acute sickness in mice with Lrrk2 mutations. Surviving Lrrk2 p.G2019S KI mice, however, had elevated oxidative stress and phosphorylated a-synuclein and tau proteins in their brains six weeks post-infection.
Activation of transposable elements is linked to a region- and cell-type-specific interferon response in Parkinson’s disease
By onStudy explores transposable elements role in Parkinson's disease neuroinflammation. TE activation in specific brain regions correlates with innate immune responses, indicating potential involvement in chronic neuroinflammation and PD progression.
Robust analytical methods for bis(monoacylglycero)phosphate profiling in health and disease
By onBMP is a crucial phospholipid in lysosomes, impacting metabolic balance and linked to neurodegenerative diseases. LC-MS methods are detailed for accurate BMP analysis, utilizing structural differences and a new CLN5 function for profiling.
Integrated Representations of Threat and Controllability in the Lateral Frontal Pole
By onEmotions can strongly influence behavior, as seen in PD paradoxical kinesia. Here, we demonstrate that anticipating threats enhances motor accuracy through interactions between the amygdala and the anterior pole of the lateral prefrontal cortex.
Evaluating single-cell ATAC-seq atlasing technologies using sequence-to-function modeling
By onSingle-cell chromatin accessibility atlases aid in training deep learning models to decode enhancer logic. HyDrop v2 improves scATAC-seq for training, showing cell numbers can compensate for lower fragment counts.
CREsted: modeling genomic and synthetic cell-type-specific enhancers across tissues and species
By onCREsted, a sequence-based deep learning model, analyzes genomic regulatory code, decodes enhancer grammar, and designs synthetic enhancers. It preprocesses single-cell data, models chromatin accessibility, and compares cell states across tissues.
ATP13A4 gates extracellular polyamine levels to control excitatory synaptogenesis
By onPolyamines are crucial for brain function. ATP13A4 is the main polyamine transporter in astrocytes, impacting astrocyte morphology, synapse formation, and neurodevelopment. Mutations in ATP13A4 are linked to neurodevelopmental disorders.
State-dependent modulation of spiny projection neurons controls levodopa-induced dyskinesia in a mouse model of Parkinson’s disease
By onLID is poorly understood, our research on dyskinetic mice show SPNs' properties oscillate during LID and are influenced by dopamine and acetylcholine signaling. Targeting M1 receptors in iSPNs reduced LID severity and improved levodopa effects.
