Dysfunction of the unfolded protein response increases neurodegeneration in aged rat hippocampus following proteasome inhibition
Dysfunctions of the ubiquitin proteasome system (UPS) have been proposed to be involved in the aetiology and/or progression of several age-related neurodegenerative disorders. However, the mechanisms linking proteasome ...
A high redox potential form of cytochrome c550 in photosystem II from Thermosynechococcus elongatus
(American Society for Biochemistry and Molecular Biology Inc., 2011)
Cytochrome c550 (cyt c550) is a component of photosystem II (PSII) from cyanobacteria, red algae, and some other eukaryotic algae. Its physiological role remains unclear. In the present work, measurements of the midpoint ...
Oxidative stress is increased in critically ill patients according to antioxidant vitamins intake, independent of severity: A cohort study
(Springer Science + Business Media, 2006)
Critically ill patients suffer from oxidative stress caused by reactive oxygen species (ROS) and reactive nitrogen species (RNS). Although ROS/RNS are constantly produced under normal circumstances, critical illness can ...
Regulation of caspase-3 processing by cIAP2 controls the switch between pro-inflammatory activation and cell death in microglia
(Nature Publishing Group, 2014)
The activation of microglia, resident immune cells of the central nervous system, and inflammation-mediated neurotoxicity are typical features of neurodegenerative diseases, for example, Alzheimer's and Parkinson's diseases. ...
Relevance of chronic stress and the two faces of microglia in Parkinson’s disease
(rontiers Research Foundation, 2015)
This review is aimed to highlight the importance of stress and glucocorticoids (GCs) in modulating the inflammatory response of brain microglia and hence its potential involvement in Parkinson’s ...
Microglia-secreted galectin-3 acts as a toll-like receptor 4 ligand and contributes to microglial activation
Inflammatory response induced by microglia plays a critical role in the demise of neuronal populations in neuroinflammatory diseases. Although the role of toll-like receptor 4 (TLR4) in microglia’s inflammatory response ...
Disruption of Amyloid Plaques Integrity Affects the Soluble Oligomers Content from Alzheimer Disease Brains
(Public Library of Science, 2014)
The implication of soluble Abeta in the Alzheimer's disease (AD) pathology is currently accepted. In fact, the content of soluble extracellular Abeta species, such as monomeric and/or oligomeric Abeta, seems to correlate ...
In vivo modification of Abeta plaque toxicity as a novel neuroprotective lithium-mediated therapy for Alzheimer’s disease pathology
(BioMed Central, 2013)
Background: Alzheimer’s disease (AD) is characterized by the abnormal accumulation of extracellular beta-amyloid (Abeta) plaques, intracellular hyperphosphorylated tau, progressive synaptic alterations, axonal dystrophies, ...
Amyloid-β reduces the expression of neuronal FAIM-L, thereby shifting the inflammatory response mediated by TNFα from neuronal protection to death
(Nature Publishing Group, 2015)
The brains of patients with Alzheimer's disease (AD) present elevated levels of tumor necrosis factor-α (TNFα), a cytokine that has a dual function in neuronal cells. On one hand, TNFα can activate neuronal apoptosis, and ...
