Anatomical Associations Between Focal Mitochondrial Metabolism and Patterns of Neurodegeneration in Amyotrophic Lateral Sclerosis

Annals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a very specific neuroimaging signature, but the molecular underpinnings of the strikingly selective anatomic involvement have not elucidated to date. Accordingly, a large neuroimaging study was conducted with 258 participants to evaluate associations between patterns of neurodegeneration and focal ...

Neuroprotection by Mitochondrial NAD Against Glutamate-Induced Excitotoxicity

Cells
Excitotoxicity is a pathological process that occurs in many neurological diseases, such as stroke or epilepsy, and is characterized by the extracellular accumulation of high concentrations of glutamate or other excitatory amino acids (EAAs ...

Insulin-like Growth Factor 1 and Transforming Growth Factor-β Stimulate Cystine/Glutamate Exchange Activity in Dental Pulp Cells [PDF]

, 2011
Introduction The growth factors insulin-like growth factor (IGF-1) and transforming growth factor-β (TGF-β) are protective to dental pulp cells in culture against the toxicity of the composite materials Durafill VS and Flow Line (Henry Schein Inc, New ...

Human Brain Contusions Contain Pathogenic Transmissible Species that Induce Progressive Cognitive Decline and Tau Pathology in Mice

Annals of Neurology, EarlyView.
Objective Traumatic brain injury (TBI) is an established risk factor for dementia, although the underlying mechanisms remain unclear. Our previous research demonstrated that a single severe TBI in wild‐type (WT) mice induces a prion‐like form of tau (tauTBI) that spreads throughout the brain, leading to memory deficits.

Activation of the Large-Conductance, Voltage, and Ca2+- Activated K+ (BK) Channel in Acute Spinal Cord Injury in the Wistar Rat Is Neuroprotective

Frontiers in Neurology, 2018
Context/Objectives: Spinal cord injury (SCI) results in significant neuronal and glial cell death resulting in impaired neurological and motor function. Uncontrolled Ca2+ entry results in excitotoxicity and cell death.

New opportunities for bioscaffold‐enabled spinal cord injury repair

BMEMat, EarlyView.
Schematic illustration of bioscaffolds for spinal cord injury repair. We summarize the effects of bioscaffold properties on SCI repair, highlight different types of bioscaffolds, various fabrication strategies, and in vivo transformations for the clinical development of SCI‐repairing bioscaffolds.

TRANSGENIC GDNF POSITIVELY INFLUENCES PROLIFERATION, DIFFERENTIATION, MATURATION AND SURVIVAL OF MOTOR NEURONS PRODUCED FROM MOUSE EMBRYONIC STEM CELLS.

Frontiers in Cellular Neuroscience, 2016
Embryonic stem cells (ESC) are pluripotent and thus can differentiate into every cell type present in the body. Directed differentiation into motor neurons has been described for pluripotent cells. Although neurotrophic factors promote neuronal survival,

Ascorbic acid enhances the inhibitory effect of aspirin on neuronal cyclooxygenase-2-mediated prostaglandin E2 production. [PDF]

, 2006
Inhibition of neuronal cyclooxygenase-2 (COX-2) and hence prostaglandin E2 (PGE2) synthesis by non-steroidal anti-inflammatory drugs has been suggested to protect neuronal cells in a variety of pathophysiological situations including Alzheimer's disease ...

Bioenergetics and glutamate excitotoxicity

Progress in Neurobiology, 1996
Bioenergetic defects and abnormalities in glutamate neurotransmission have both been proposed to play important roles in neurological diseases of varying chronology, etiology and pathology. Recent experimental evidence suggests an intimate relationship between these two systems.
