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.

Structural Determinants of Oligomerization of the Aquaporin-4 Channel [PDF]
The aquaporin (AQP) family of integral membrane protein channels mediate cellular water and solute flow. Although qualitative and quantitative differences in channel permeability, selectivity, subcellular localization, and trafficking responses have been observed for different members of the AQP family, the signature homotetrameric quaternary structure

ABSTRACT Objective To evaluate the diagnostic accuracy of glial fibrillary acidic protein (GFAP) measured in dried plasma spots versus conventional plasma‐ and serum‐GFAP testing for assessment of disease severity in aquaporin‐4 immunoglobulin G–positive neuromyelitis optica spectrum disorder (AQP4‐IgG+ NMOSD).

Aquaporin-4 and Parkinson’s Disease
The water-selective channel aquaporin-4 (AQP4) is implicated in water homeostasis and the functioning of the glymphatic system, which eliminates various metabolites from the brain tissue, including amyloidogenic proteins. Misfolding of the α-synuclein protein and its post-translational modifications play a crucial role in the development of Parkinson’s

Aquaporin‐4 Overexpression in Rat ALS Model [PDF]
AbstractOnset of motoneuron death characterizing amyotrophic lateral sclerosis (ALS) is closely linked to modified astrocytic and glial environments. Here, we show that in the spinal cord from transgenic rat overexpressing mutated human SOD1, aquaporin‐4 mRNA and protein are specifically overexpressed in the gray matter at end stage of disease ...

Inebilizumab in AQP4‐Seropositive NMOSD: One‐Year Follow‐Up From a Multicenter, Real‐World Study
ABSTRACT Objective Real‐world evidence on inebilizumab among neuromyelitis optica spectrum disorder (NMOSD) patients is lacking. This study assessed inebilizumab among Chinese patients with aquaporin 4 autoantibody (AQP4‐IgG)‐seropositive NMOSD in a real‐world setting.

Precision Matters: Minor Concentration Deviations of DMSO May Cause Major Efficacy Shifts
Low‐concentration dimethyl sulfoxide (DMSO) has long been regarded as biologically safe in drug discovery. However, increasing DMSO from 0.1% to 0.9% reduces photosensitizer PNA‐9 particle size from 657 nm to 260 nm, enhancing endocytosis and photodynamic therapy outcomes.

Detection of anti-aquaporin-4 autoantibodies in the sera of Chinese neuromyelitis optica patients.
In this study, we recruited 10 neuromyelitis optica patients, two multiple sclerosis patients and two myelitis patients. Chinese hamster lung fibroblast (V79) cells transfected with a human aquaporin-4-mCherry fusion protein gene were used to detect anti-

Combined effects of aquaporin-4 and hypoxia produce age-related hydrocephalus [PDF]
Aquaporin-4, present in ependymal cells, in glia limiting and abundantly in pericapillary astrocyte foot pro cesses, and aquaporin-1, expressed in choroid plexus epithelial cells, play an important role in cerebrospinal fluid production and may be ...
