Biomolecular condensates formed via liquid-liquid phase separation regulate essential cellular processes, with dysregulation implicated in neurodegeneration and cancer. Nuclear magnetic resonance (NMR) spectroscopy provides label-free, atomic-resolution insights into condensate composition, stoichiometry, physicochemical properties (e.g., viscosity and water content), and molecular interactions, overcoming the limitations of imaging and bulk techniques. [...]

Brain clearance pathways via the interstitial fluid and cerebrospinal fluid are essential for maintaining homeostasis and removing metabolic waste. Disruptions in these processes are linked to neurodegenerative diseases, particularly Alzheimer's Disease (AD), where an imbalance between amyloid β (Aβ) production and clearance leads to cerebral amyloidosis. [...]

We developed a high-content screening to investigate how Alzheimer's disease (AD) genetic risk factors may affect synaptic mechanisms in rat primary neuronal cultures. Of the target genes identified, we found that Plcg2 downregulation in mouse dentate gyrus neurons consistently disrupted dendritic morphology and synaptic function. [...]

C9orf72 hexanucleotide repeat expansion (C9-HRE) is a major genetic cause of amyotrophic lateral sclerosis and frontotemporal dementia (FTD). However, approximately half of the FTD patients are sporadic without a clear genetic background. [...]

Transformation in the neurosciences in biomarkers is enabling novel therapeutic strategies targeting earlier stages of disease prior to onset of clinical symptoms. Emerging progress in the area of synucleinopathies, including Parkinson's disease (PD) and dementia with Lewy bodies (DLB) have significant implications for clinical trials. [...]

BackgroundThe Parkinson's Disease (PD) Home Diary (HD) is a common clinical outcome measure, but studies show only fair agreement between clinical observer and patient assessments, with no significant improvement after patient training.ObjectivesTo investigate the agreement between a clinical observer and relatives of PD patients when assessing the patient's motor status in the HD. Agreement was also assessed for relative-patient and patient-observer pairs.MethodsThis observational study included 28 PD patients with motor fluctuations and their relatives. [...]

Neonatal hypoxia-ischemia (HI) remains a major global cause of neonatal morbidity and mortality. To develop effective therapeutic strategies, a deeper understanding of the acute inflammatory processes following HI is required. [...]

The conversion of native prion protein (PrP) into its misfolded isoform, scrapie (PrPSc) and its intracellular accumulation represent central events in the pathogenesis of prion diseases. Reduction of native PrP in the central nervous system (CNS) has emerged as a promising strategy for treatment and prevention of prion diseases in humans. [...]

Psychosocial interventions are essential to support people living with dementia and their carers. A consensus on what is most important for research on psychosocial intervention in dementia and how intervention studies should best be conducted is currently lacking. [...]
