Amyloid-forming peptides are increasingly recognized as dynamic regulators at the host-pathogen interface, yet how environmental factors control their assembly and activity remains poorly understood. Here, RNA acts as a concentration-dependent regulator of two sequence-related α-helical peptides with fundamentally different assembly behaviors: the cross-α amyloid-forming Staphylococcus aureus virulence factor PSMα3 and the non-amyloidogenic human host-defense peptide LL-37. [...]

Peptidylprolyl isomerases (PPIases) catalyze cis/trans isomerization of prolines. The PPIase CypA colocalizes with the Parkinson's disease (PD)-associated protein α-synuclein in cells and interacts with α-synuclein oligomers. [...]

Introducing the 'DemenzKompetenz' model for German long-term care: Development of a dementia-specific nurse-led care model Abstract: Background: To meet the complex care needs of people with dementia, academically trained nurses must be established in care practice. The implementation of extended nursing roles in German inpatient long-term care requires a reorganization of tasks within the professional care team. [...]

Prion diseases, of which Creutzfeldt-Jakob disease is the most common, are fatal neurodegenerative disorders and are often rapidly progressive. They are associated with a significant palliative care burden for patients and families, ranging from prognostic uncertainty to complex symptom management to caregiver distress. [...]

Higher predicted brain age difference has been associated with several psychiatric disorders. Generalized anxiety disorder (GAD) is associated with markers of accelerated aging. [...]

CSF proteomics has emerged as a valuable strategy for identifying diagnostic and prognostic biomarkers in amyotrophic lateral sclerosis (ALS). However, the limited availability and volumes of CSF samples restrict the broader clinical application of CSF-based biomarker panels. [...]

Alzheimer's disease (AD) is characterised by the accumulation of β-amyloid (Aβ) and tau proteins, resulting in neurodegeneration and cognitive decline. Although Aβ and tau disrupt synaptic function, the association linking these molecular pathologies to network-level dysfunction and memory impairment remains poorly understood. [...]

The tumor microenvironment (TME) actively contributes to pancreatic ductal adenocarcinoma (PDAC) pathogenesis through dynamic bidirectional tumor-stroma interactions. In this study, we demonstrated that ATM-deficient tumor epithelium reprograms the TME in a genotype-specific manner to enhance cancer aggressiveness. [...]

Pharmacogenetics-guided prescribing may reduce adverse drug reactions by 30%. European and American expert groups (Dutch Pharmacogenetics Working Group and Clinical Implementation Consortium) issue genotype-based dosage recommendations, but pharmacogenetic testing is still not routinely used. [...]
