Innate defenses of the respiratory epithelium are the first barrier against incoming respiratory viruses. To understand the contribution of both basal (tonic) and induced interferon (IFN) to antiviral defenses in a physiologically relevant system, we established air-liquid interface (ALI) cultures of primary human bronchial epithelium (HBE) and small airway epithelium (HSE). [...]

Simian immunodeficiency viruses (SIVs) have crossed from apes to humans at least four times, but only one event gave rise to the AIDS pandemic. The host barriers that pandemic HIV-1 group M (major) strains overcame to spread efficiently in humans remain poorly understood. [...]

Amyloid assembly in vivo occurs in complex environments where multiple aggregation-prone species coexist. Aβ and medin are prevalent amyloids in ageing humans that co-localize in cerebral amyloid angiopathy (CAA), yet their structural interactions remain poorly understood. [...]

Blood-based biomarkers are increasingly used to support the identification of Alzheimer's disease (AD) in clinical and research settings. However, variability between analytical platforms limits their interchangeability and may affect their clinical interpretation. [...]

BackgroundPeople with Down syndrome (DS) have a significantly increased risk of developing early-onset Alzheimer's disease. For example, a longitudinal study by McCarron et al. [...]

BackgroundLow socioeconomic status is associated with a higher risk for a number of health conditions, including cognitive impairment.ObjectiveWhile the association with economic indicators has been well researched, aim of this paper was to investigate specifically the association between non-economic social deprivation and cognitive functioning later in life.MethodsParticipants without objective cognitive impairment at baseline (n = 91 controls, n = 106 with subjective cognitive decline) of the multicenter DZNE-Longitudinal Cognitive Impairment and Dementia Study (DELCODE) filled out a posthoc survey on social deprivation. Factor analysis identified four non-economic domains of social deprivation (Residential area conditions, Accessibility, Neighborhood support, Household distress). [...]

Recent findings indicate oligodendrocytes (ODCs) and their progenitors are vulnerable in Parkinson's disease (PD) pathogenesis. Notably, oligodendrocyte precursor cells (OPCs) exhibit high endogenous expression of the PD-relevant gene LRRK2. [...]

Progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) are primary tauopathies defined by aggregation of four-repeat (4R) tau, yet early in vivo diagnosis remains limited by the dissociation between clinical phenotype and molecular pathology. Clinical presentations are heterogeneous, evolve over time, and frequently overlap with Alzheimer's disease, synucleinopathies, and mixed pathologies, particularly in corticobasal syndrome. [...]

To investigate the relationship between intracranial pressure (ICP), anterior pituitary hormones, and structural brain changes in women with idiopathic intracranial hypertension (IIH).Eighteen women with therapy-refractory IIH underwent lumbar puncture, endocrine assessment, and high-resolution brain MRI. Serum levels of pituitary hormones were correlated with ICP and radiological parameters including pituitary volume, flattening, and optic nerve (ON) and optic nerve sheath (ONS) volume. [...]

[18F]FDG-PET and β-amyloid-PET are established tools for assessing biomarker status in Alzheimer's disease. In this study, we evaluated the potential of early-phase [18F]florbetaben (FBB) PET as a functional proxy for [18F]FDG-PET in preclinical Alzheimer's disease models by examining regional perfusion and glucose metabolism in two transgenic mouse lines.
