This study uses an AAV model to show that aggregation-prone tau variants spread more extensively in the mouse brain, suggesting extracellular vesicles may contribute to tau propagation.

This study examines age-related changes in microglia and perivascular macrophages in microcebe primates, finding increased HLA-DR+ expression in white matter and perivascular regions with aging.

The paper develops a peptide, PEP 3, that disrupts the LRRK2/PP1 interaction and shows promise as a therapeutic for Parkinson's disease by reducing dopaminergic cell death and alpha-synuclein phosphorylation.

This study characterizes astrocyte diversity and age-related changes in the mouse lemur brain, identifying region-specific vulnerabilities and distinct astrocyte subtypes.

This study shows that activating the JAK2-STAT3 pathway in astrocytes reduces mutant Huntingtin aggregates and improves disease outcomes in Huntington's disease models.

This study shows that injecting human Alzheimer's brain extracts into mice with amyloid-beta plaques induces tau pathology, memory deficits, and synaptic loss, with neuritic plaques linked to synaptic impairment.

This study investigates the role of reactive astrocytes in Alzheimer's disease by modulating the JAK2-STAT3 pathway in 3xTg-AD mice, finding no effect on Tau or amyloid pathology but behavioral changes.
