Physiological Roles of Aquaporin-4 in Brain
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.

It is currently not well understood how cells regulate basic properties, e.g., volume and mechanics within dense multicellular environments like tumors. Here, we show that different cell types of cancer and also normal cells largely decrease their nuclear and cellular volumes in emerging cell clusters and that this is partly driven by cell cycle shifts.

Spatial model of convective solute transport in brain extracellular space does not support a "glymphatic" mechanism. [PDF]
A "glymphatic system," which involves convective fluid transport from para-arterial to paravenous cerebrospinal fluid through brain extracellular space (ECS), has been proposed to account for solute clearance in brain, and aquaporin-4 water channels in ...

Astrocytic LRP1 mediates brain Aβ clearance and impacts amyloid deposition [PDF]
Accumulation and deposition of amyloid-β (Aβ) in the brain represent an early and perhaps necessary step in the pathogenesis of Alzheimer's disease (AD).

The role of microglia has emerged as a critical driver of disease progression in multiple sclerosis (MS), but we lack broadly applicable monitoring tools. Here, we investigated whether hyperreflective foci (HRF), as detected by optical coherence tomography (OCT) within the inner nuclear layer (INL) of the retina, can be used as a marker for microglial ...

Neuromyelitis optica - an update: 2007-2009
Neuromyelitis optica is an inflammatory demyelinating disorder of the central nervous system. The discovery of a specific antibody (NMO IgG /aquaporin-4 antibody) in patients with this condition has led to a marked revival of research on the disease ...

Barrier mechanisms in neonatal stroke. [PDF]
Clinical data continue to reveal that the incidence of perinatal stroke is high, similar to that in the elderly. Perinatal stroke leads to significant morbidity and severe long-term neurological and cognitive deficits, including cerebral palsy ...

Clock genes regulate Ca2+ signaling and mitochondrial bioenergetics to inhibit Sjogren's disease
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjogren's disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA seq, and mitochondrial activity were used to investigate the effects of ...

Aim Hyponatremia is a common yet potentially serious adverse event associated with antidepressants. Identifying the antidepressant class with the least risk of hyponatremia would improve patient safety. Methods Using electronic medical records from 15 hospitals standardized into Observational Medical Outcomes Partnership Common Data Model (2003–2023 ...

Ammonia toxicity: from head to toe? [PDF]
Ammonia is diffused and transported across all plasma membranes. This entails that hyperammonemia leads to an increase in ammonia in all organs and tissues.
