Papers on AQP4
Structural Determinants of Oligomerization of the Aquaporin-4 Channel.

Mukherjee et al., Calcutta, India. In Ann Indian Acad Neurol, Sep 2015
Neuromyelitis optica (NMO) is an autoimmune demyelinating condition of the central nervous system often associated with aquaporin-4 (AQP4) autoantibodies manifesting as severe optic neuritis and long segment myelitis with tendency to relapse.
Effect of progesterone intervention on the dynamic changes of AQP-4 in hypoxic-ischaemic brain damage.
Wang et al., Xinxiang, China. In Int J Clin Exp Med, 2014
To observe the effect of progesterone (PROG) on blood-brain barrier (BBB) permeability, brain tissue water content and dynamic changes of aquaporin-4 (AQP-4) in neonatal rats with hypoxic-ischaemic brain damage (HIBD).
Screening feature genes of astrocytoma using a combined method of microarray gene expression profiling and bioinformatics analysis.
Yang et al., Huzhou, China. In Int J Clin Exp Med, 2014
A total of 3072 genes, including 1799 up-regulated genes and 1273 down-regulated genes, were filtered as DEGs, and we learnt that the DEGs including AQP4, PMP2, SRARCL1 and SLC1A2CAMs etc and that AQP4 was most significantly related to cell osmotic pressure.
Hypersensitivity Responses in the Central Nervous System.
Owens et al., Odense, Denmark. In Front Immunol, 2014
Serum-derived autoantibodies with predominant specificity for the astrocyte water channel aquaporin-4 (AQP4) are implicated as inducers of pathology in neuromyelitis optica (NMO), a central nervous system (CNS) demyelinating disease where activated neutrophils infiltrate, unlike in MS.
Neuromyelitis optica in children: a review of the literature.
Tuncer-Kurne et al., Ankara, Turkey. In Turk J Pediatr, 2014
The discovery of an autoantibody called NMO-IgG, which targets aquaporin-4, the main water channel in the CNS, gave a new direction to understanding the underlying immunologic mechanisms.
Aquaporins: important but elusive drug targets.
Papadopoulos et al., San Francisco, United States. In Nat Rev Drug Discov, 2014
Moreover, loss-of-function mutations in human AQPs cause congenital cataracts (AQP0) and nephrogenic diabetes insipidus (AQP2), and autoantibodies against AQP4 cause the autoimmune demyelinating disease neuromyelitis optica.
Physiological roles of aquaporin-4 in brain.
Ottersen et al., In Physiol Rev, 2013
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.

Wingerchuk et al., Rochester, United States. In Lancet Neurol, 2013
BACKGROUND: Complement activation after binding of an IgG autoantibody to aquaporin 4 (AQP4) is thought to be a major determinant of CNS inflammation and astrocytic injury in neuromyelitis optica.
