The paper identifies a SNCA mutation causing juvenile-onset synucleinopathy and describes the structural features of α-synuclein filaments associated with the disease.

This study shows that IFNγ from CD4+ T cells drives neuroinflammation and demyelination in a mouse model of MSA.

This paper performs a large meta-analysis of GWAS in dementia with Lewy bodies, identifying sex-specific genetic risk signals and highlighting the need for larger cohorts.

This study identifies Ras-Sindoor, an Ayurvedic compound, as neuroprotective in Drosophila Parkinson's models by improving locomotion, reducing cell death, and extending lifespan.

This study shows that elevated alpha-synuclein in neurons reduces microglial phagocytosis in a co-culture model derived from SNCA triplication iPSCs.

This study examines the association of NPC1 variants with Parkinson's disease, REM-sleep behavior disorder, and dementia with Lewy bodies in European cohorts and finds no significant associations.

This study shows that SNCA deletion disrupts olfactory sensory neuron projection via the NCK2-EphA4 pathway, contributing to olfactory deficits in synucleinopathies.

Vutiglabridin, a clinical-stage drug for obesity, shows neuroprotective effects in Parkinson's disease models by targeting mitochondrial PON2.

This study investigates how Synj1 deficiency affects lysosomal function in ventral midbrain neurons, revealing impaired clearance of mutant alpha-synuclein in axons.

This study identifies neuroanatomical and cognitive biomarkers of alpha-synuclein propagation in a mouse model, showing early cognitive deficits and brain atrophy linked to prion-like spread of misfolded alpha-synuclein.

This study investigates how monomeric and fibrillar alpha-synuclein interact with synaptic vesicles, showing fibrils disintegrate vesicles and increase neuronal uptake, potentially contributing to Parkinson's disease pathology.

This study identifies that pathological α-synuclein destabilizes the TSC1-TSC2 complex, activates mTORC1, and enhances protein translation, contributing to neurodegeneration in Parkinson's disease.

The paper shows that PKB/AKT activation protects dopamine neurons from ER stress and -syn aggregation via Cathepsins B and D, suggesting a potential gene therapy approach for Parkinson's disease.

This study shows that mitochondrial protein import stress increases alpha-synuclein aggregation and neurodegeneration without affecting bioenergetics in a Parkinson's disease mouse model.

This study shows that LRRK2 G2019S mutation interacts with low-grade inflammation and aging to promote gut and peripheral immune activation before nigrostriatal degeneration in mice.

This paper develops a mathematical model to analyze the dynamic behavior of autophagy in clearing aggregated α-synuclein, revealing tri-stability and feedback mechanisms relevant to Parkinson's disease progression.

This study shows that dopamine-modified hyaluronic acid (DA-HA) has dopamine-like functionality with reduced autoxidation and toxicity, making it a potential therapeutic alternative to L-DOPA for Parkinson's disease.

This study examines the regional distribution of neurofilaments in Parkinson's disease and its association with pathological markers and MRI measures of brain atrophy and diffusivity.

The paper identifies and replicates epistatic variant-variant interactions in Parkinson's disease across genetically diverse populations using a new pipeline called VARI3.

In Parkinson's disease models, alpha-synuclein overexpression sensitizes neurons to ferroptosis, potentially by suppressing NRF2 protein, while Nrf2 loss increases ferroptosis markers, alpha-synuclein pathology, and behavioral deficits.

The paper identifies TLK2 as a key regulator of calcium overload-induced mitochondrial and autophagy dysfunction in Parkinson's disease using Drosophila and mammalian models.

The paper identifies six novel α-synuclein fibril assemblies from cerebrospinal fluid samples and shows they have distinct functional properties despite no single structural feature predicting their function.

The paper reports cryo-EM structures of α-synuclein filaments from Parkinson's disease, PD dementia, and dementia with Lewy bodies, showing they are composed of a single protofilament distinct from those in multiple system atrophy.
