This article describes pathogenic concepts and factors, in particular glycolipid abnormalities, that create cell dysfunction and synaptic loss in neurodegenerative diseases. By phenocopying lysosomal storage disorders, such as Gaucher disease and related disorders, age- and dose-dependent changes in glycolipid cell metabolism can lead to Parkinson’...

Studying the non-motor disorders of the prodromal phase of Parkinson's disease (PD) is of great importance because of their negative impact on patient's quality of life. Classical neurotoxic animal models of PD generally unable the exploration of the progression of the non-motor phase of the prodromal stage of the disease. The aim of this study is ...

Redistribution of the water channel aquaporin-4 (AQP4) away from astrocyte endfeet and into parenchymal processes is a striking histological feature in mouse models of Alzheimer’s disease (AD) and other neurological conditions with prominent astrogliosis. AQP4 redistribution has been proposed to impair bulk Aβ clearance in AD, resulting in increase...

Neuroinflammation is the coordinated response of the central nervous system (CNS) to threats to its integrity posed by a variety of conditions, including autoimmunity, pathogens and trauma. Activated astrocytes, in concert with other cellular elements of the CNS and immune system, are important players in the modulation of the neuroinflammatory res...

Parkinson’s disease is characterized by a proteinopathy that includes aggregates of α-synuclein. A recent hypothesis proposes a prion-like spreading mechanism for this α-synucleinopathy. Early neuropathological deposits occur, among others, in the anterior olfactory nucleus (AON). This study investigates the anterograde and/or retrograde transmissi...

Hyperintensity in the subcortical white matter on the diffusion-weighted magnetic resonance image has been described recently, in association with partial status epilepticus. Although this reduced subcortical diffusion is typically seen in patients with acute encephalopathy with biphasic seizures and late reduced diffusion (AESD), the exact pathoph...

Neural stem cells (NSCs) can differentiate into both neurons and glia after transplantation into spinal cord injury (SCI) sites. The neuronal component of stem cell grafts has the potential to form functional synaptic relays across the lesion site. The glial component may reform a blood-spinal cord barrier, support neuronal function, and contribute...
HIV-associated neurocognitive disorders (HAND) persist in the era of effective combined antiretroviral therapy (cART). A large body of literature suggests that mitochondrial dysfunction is a prospective etiology of HAND in the cART era. While viral load is often suppressed and the immune system remains intact in HIV+ patients on cART, evidence sugg...

Astroglia serve as a critical role in metabolic and neurotrophic support to neurons. The loss of astroglia-derived neurotrophic effects could be a primary contributor to Parkinson's disease (PD). Thus, understanding astroglia functions is an important strategy for enhancing neuronal survival. Nuclear factor erythroid 2-related factor 2 (Nrf2) plays...
