The complexity of extracellular vesicles: Bridging the gap between cellular communication and neuropathology
In this report, we review the roles that extracellular vesicles can play in biological processes and cellular dysfunction and pathobiology, particularly neurodegenerative diseases. We also examine the potential translational impacts of extracellular vesicles in diagnostics and therapeutic development. ER: endoplasmic reticulum; ROS: reactive oxygen species. AbstractBrain-derived extracellular vesicles (EVs) serve a prominent role in maintaining homeostasis and contributing to pathology in health and disease. This review establishes a crucial link between physiological processes leading to EV biogenesis and their impacts on...

Variant ‐specific effects of GBA1 mutations on dopaminergic neuron proteostasis
Glucocerenrosidase1 (GBA1) mutations cause disruptions in endoplasmic reticulum (ER) and lysosome-related proteostasis pathways in induced pluripotent stem cell (iPSC)-derived dopaminergic neurons. SevereGBA1 mutations lead to increased ER stress (increased binding immunoglobulin protein (BiP) and protein disulfide isomerase (PDI) levels), total ubiquitination rates, and unfolded protein response (UPR). Defective chaperone-mediated autophagy (decreased heat-shock cognate protein 70 (HSC70) levels and decreased co-localization of lysosomal-associated membrane protein 2A (LAMP2A) and HSC70) is observed in iPSC-derived dopami...

Infiltration of immune cells to the brain and its relation to the pathogenesis of Alzheimer's and Parkinson's diseases
The disruption of the neurovascular unit and the infiltration of the peripheral immune cells into the central nervous system are hallmarks of neurodegenerative diseases. However, so far, the participation of infiltrating cells in the progression of these diseases has not been completely defined. In this work, we gather the evidence that exists until now which proposes the key events involved in the pathogenesis of the two main neurodegenerative diseases: Alzheimer's and Parkinson's diseases. We detail the alterations in the components that typically keep the neurovascular unit semi-permeable to the cellular interactions th...

Variant ‐specific in vitro neuronal network phenotypes and drug sensitivity in SCN2A developmental and epileptic encephalopathy
This study aims to assess the impact of GoF and LoFSCN2A variants on cultured neuronal network activity and explore their modulation by selected antiseizure medications (ASM). To this end, primary cortical cultures were generated from two knock-in mouse lines carrying variants corresponding to human GoFSCN2A p.R1882Q and LoF p.R853Q DEE variant. In  vitro neuronal network activity and responses to ASM were analyzed using multielectrode array (MEA) between 2 and 4 weeks in culture. TheSCN2A p.R1882Q neuronal cultures showed significantly greater mean firing and burst firing. Their network synchronicity was also higher. I...

Amyloid pathology mediates the associations between plasma fibrinogen and cognition in non ‐demented adults
The current study aimed to comprehensively examine the interrelationships of fibrinogen, cognitive decline, and cerebrospinal fluid Alzheimer's disease biomarkers in non-demented individuals. Our findings were as follows: (1) Increased fibrinogen levels were associated with cognitive decline. (2) Increased fibrinogen levels were associated with A β pathology. (3) The impact of fibrinogen on cognition could be mediated by Aβ pathology. AbstractThough previous studies revealed the potential associations of elevated levels of plasma fibrinogen with dementia, there is still limited understanding regarding the influence of Al...

Where alcohol use disorder meets interoception: A meta ‐analytic view on structural and functional neuroimaging data
We examined the results of two meta-analyses of gray matter reduction in alcohol use disorders (AUD) and functional representations of interoception (INT) for spatial convergence. No overlap was found (A). However, the AUD clusters are located in regions of the salience and sensorimotor networks that are strongly associated with the interoception clusters, as determined by coactivation (MACM; B, C) and resting-state analyses (D). Weak salience mapping may account for Interoceptive deficits in AUD that may be influenced by sensory stimulation. AbstractAlcohol use disorder (AUD) has been associated with changes in the proces...

Dual effects of TGF ‐β inhibitor in ALS ‐ inhibit contracture and neurodegeneration
We found that halofuginone inhibits contracture and neurodegeneration by blocking the TGF- β/Smad signaling in amyotrophic lateral sclerosis (ALS). Halofuginone inhibits fibrosis in fibroblasts derived from SOD1 G93A mice. In SOD1 G93A mice, excessive TGF-β-induced fibrosis of the peripheral neuromuscular system causes joint contracture and muscle degeneration, resulting in motor dysfun ction, which is suppressed by halofuginone. Halofuginone also reduces glial cell-induced neuroinflammation and neuronal apoptosis. These dual therapeutic effects on both the neuromuscular and the central nervous systems with halofuginone ...
