Cell-based assays (CBA) have increased the sensitivity of the neuromyelitis optica (NMO)-IgG/aquaporin-4-antibody detection compared to classical tissue-based indirect assays. We describe the sensitivity of an optimized immunohistochemistry (IHC-o) to detect NMO-IgG/aquaporin-4-antibody in comparison with that of two CBA: an in-house (CBA-ih) and a commercial (CBA-c) assay (Euroimmun, Germany)....

Aquaporin-4 (AQP4) is one of the most abundant molecules in the brain and is particularly prevalent in astrocytic membranes at the blood-brain and brain-liquor interfaces. While AQP4 has been implicated in a number of pathophysiological processes, its role in brain physiology has remained elusive. Only recently has evidence accumulated to suggest that AQP4 is involved in such diverse functions ...

Abstract Introduction Recent studies have found that mid-life sleep disruption is associated with the development of Alzheimer’s disease-related neuropathology, including deposition amyloid beta. Yet, mechanism connecting disruption, particularly over chronic timescales, and downstream pathology remains unclear. Methods In this study, we evaluated impact has on neuroinflammation beta plaques in...
