RETRACTED: AQP4-dependent water transport plays a functional role in exercise-induced skeletal muscle adaptations.

PLoS ONE, 2013
In this study we assess the functional role of Aquaporin-4 (AQP4) in the skeletal muscle by analyzing whether physical activity modulates AQP4 expression and whether the absence of AQP4 has an effect on osmotic behavior, muscle contractile properties ...

Effects of erythropoietin and methylprednisolone on AQP4 expression in astrocytes

Molecular Medicine Reports, 2017
Methylprednisolone sodium succinate (MPSS) has been suggested as a treatment for spinal cord injury (SCI), but its use has been limited due to its adverse effects. Erythropoietin (EPO) has been suggested as a promising candidate for limiting SCI in mammals.

Brain Clearance of Contrast Agent in Intravenous DCE‐MRI Is Measurable and Cannot Be Explained by Clearance Across the BBB Alone

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To determine the feasibility of measuring brain clearance of gadolinium contrast agent using standard intravenous DCE‐MRI acquisitions and evaluate the contribution of blood–brain barrier (BBB) and non‐BBB clearance routes. Methods Uptake and extended Tofts models were fit to DCE‐MRI data from people with Parkinson's disease, post ...

IgG Subclass (IgG1‐4) and IgA Autoantibody Profiles Against Muscle‐Specific Kinase in a Greek Cohort

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Muscle‐specific kinase myasthenia gravis (MuSK‐MG) is an autoimmune neuromuscular disorder predominantly mediated by IgG4 autoantibodies disrupting MuSK signaling. The contribution of other isotypes remains incompletely defined. We characterized the serological profile of a Greek cohort of MuSK‐MG patients.

With Regard to the Expression Status of Sarcolemmal Aquaporin 4 in Human Muscular Dystrophies

Neurology and Clinical Neuroscience, EarlyView.
ABSTRACT Human muscular dystrophies are inherited muscle‐wasting diseases caused by the various kinds of gene mutations. Among them, Duchenne muscular dystrophy (DMD) is a representative type. Before the discovery of the causative dystrophin gene of DMD, the fragile myofiber plasma membrane was thought to be the trigger of myofiber necrosis in DMD ...

Current Cell/Organoid and Animal Models for Primary Sclerosing Cholangitis

Portal Hypertension &Cirrhosis, EarlyView.
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease with limited therapeutic options and a marked risk of progression to biliary fibrosis, cirrhosis, and malignancy. Progress in PSC research has been hindered by the lack of models that faithfully recapitulate the complex biliary microenvironment and disease heterogeneity ...

AQP4-specific T cells determine lesion localization in the CNS in a model of NMOSD

Acta Neuropathologica Communications
Neuromyelitis optica spectrum disorder (NMOSD) is a paradigmatic autoimmune disease of the central nervous system (CNS), in which the water channel protein Aquaporin-4 (AQP4) is targeted by a self-reactive immune response.

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Wasteosomes accumulate in periventricular white matter hyperintensities and exhibit complex relationships with mixed pathology, sclerotic index, and perivascular space

Brain Pathology, EarlyView.
In a mixed diagnostic cohort of pathologically diagnosed Alzheimer's disease, cerebrovascular disease, mixed pathology, and control tissue, we connected the histopathological wasteosome profile in periventricular (PV) brain sections to 7T FLAIR‐MRI confirmed PV white matter hyperintensities (WMHs), vascular stenosis and perivascular space size ...
