Aquaporin-4 Expression during Toxic and Autoimmune Demyelination

Cells, 2020
The water channel protein aquaporin-4 (AQP4) is required for a normal rate of water exchange across the blood–brain interface. Following the discovery that AQP4 is a possible autoantigen in neuromyelitis optica, the function of AQP4 in health and disease

PENGARUH BISAKODIL TERHADAP EKSPRESI TRANSPORTER AQUAPORIN-3, AQUAPORIN-4 DAN PPARγ PADA KONSTIPASI YANG DIINDUKSI MORFIN [PDF]

, 2019
Morphine is an opioid analgesic used to treat acute pain and chronic pain. Morphine can cause constipation due to the effect on the enteric nervous system and increased level of aquaporin transporter expression in colon. The administration of morphine is

Structural basis of aquaporin-4 autoantibody binding in neuromyelitis optica [PDF]

Neuromyelitis optica (NMO) is an autoimmune disease of the central nervous system where pathogenic autoantibodies target the water channel aquaporin-4 on human astrocytes causing neurological impairment. Autoantibody binding leads to complement-dependent

Entorhinal Astrocyte Transplants Restore Spatial Exploration and Alleviate Amyloid‐Beta Pathology in Alzheimer's Mice

Advanced Science, EarlyView.
Impaired MEC astrocytic Ca2+ signaling is associated with fragmented spatial exploration in AD mice. Region‐specific glial progenitor transplantation generates engrafted astrocytes that are accompanied by improved AQP4 polarization, reduced amyloid‐β‐associated pathology, attenuated neuroinflammation, preserved synaptic integrity, and ameliorated ...

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

Advanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

Neuromyelitis optica - an update: 2007-2009

Annals of Indian Academy of Neurology, 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 ...

A Biofabricated Human Acinus‐on‐a‐Chip Unveils Mechanotransductive Drivers of Ventilator‐Induced Lung Injury via Decoupling Volutrauma and Barotrauma

Advanced Science, EarlyView.
This bioinspired acinus‐on‐a‐chip recapitulates VILI pathology, revealing that volutrauma drives P53/NF‐κB pathways while barotrauma triggers mitochondrial‐Wnt dysregulation. A fibrotic transitional cell cluster was identified. Pharmacological interventions targeting these pathways significantly ameliorated injury, establishing a mechanobiological ...

New isoforms of rat Aquaporin-4

Genomics, 2008
Aquaporin-4 (AQP4) is a brain aquaporin implicated in the pathophysiology of numerous clinical conditions including brain edema. Here we show that rat AQP4 has six cDNA isoforms, formed by alternative splicing. These are named AQP4a-f, where AQP4a and AQP4c correspond to the two classical M1 and M23 isoforms, respectively.

CRISPR and Gene Augmentation Rescue Trabecular Meshwork Dysfunction in iPSC Models of Lowe Syndrome

Advanced Science, EarlyView.
By modeling Lowe syndrome using patient‐derived iPSCs, this study establishes a human disease model that faithfully recapitulates OCRL deficiency‐associated ciliary and cytoskeletal defects. The model enables evaluation of both mutation‐agnostic DNA augmentation and CRISPR‐mediated mutation correction strategies, both of which restore OCRL function and
