Dysfunction of the unfolded protein response increases neurodegeneration in aged rat hippocampus following proteasome inhibition
(Wiley-Blackwell, 2009)
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 ...

Effect of oxidative stress, produced by cumene hydroperoxide, on the various steps of protein synthesis. Modifications of elongation factor-2
(American Society for Biochemistry and Molecular Biology, 1996)
We have studied the effect of oxidative stress on protein synthesis in rat liver. Cumene hydroperoxide (CH) was used as an oxidant agent. The approach used was to determine the ribosomal state of aggregation and the time ...

Neuromelanin activates proinflammatory microglia through a caspase-8-dependent mechanism
(BioMed Central, 2015)
Background We have uncovered a caspase-dependent (caspase-8/caspase-3/7) signaling governing microglia activation and associated neurotoxicity. Importantly, a profuse non-nuclear activation of cleaved caspases 8 and 3 was ...

Plaque-Associated Oligomeric Amyloid-Beta Drives Early Synaptotoxicity in APP/PS1 Mice Hippocampus: Ultrastructural Pathology Analysis
(Frontiers Media, 2021)
Alzheimer’s disease (AD) is a devastating neurodegenerative disorder characterized by initial memory impairments that progress to dementia. In this sense, synaptic dysfunction and loss have been established as the pathological ...

Blockade of the Interaction of Calcineurin with FOXO in Astrocytes Protects Against Amyloid-β-Induced Neuronal Death
(IOS Press, 2016-06-07)
Astrocytes actively participate in neuro-inflammatory processes associated to Alzheimer’s disease (AD), and other brain pathologies. We recently showed that an astrocyte-specific intracellular signaling pathway involving ...

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, ...

Altered Intracellular Ca2+ Homeostasis in Nerve Terminals of Severe Spinal Muscular Atrophy Mice
(SOC NEUROSCIENCE, 2010)
Low levels of survival motor neuron (SMN) protein result in spinal muscular atrophy (SMA), a severe genetic disease characterized by motor impairment and premature lethality. Although SMN is a ubiquitous protein, motor ...

Morphological and functional remodelling of the neuromuscular junction by skeletal muscle PGC-1 alpha
(NATURE PUBLISHING GROUP, 2014-04-04)
The neuromuscular junction (NMJ) exhibits high morphological and functional plasticity. In the mature muscle, the relative levels of physical activity are the major determinants of NMJ function. Classically, motor ...

Physical exercise and myokines
(Spanish Society of Anti-Aging Medicine and Longevity, 2019-10)
Among the types of muscles present in the body is skeletal muscle, which is the one that allows the development of physical activity thanks to the contractile activity of its muscle cells. It is known that physical ...

Folic acid supplementation: some practical aspects
(Federation of Anti-Aging Medicine Societies, 2012)
Since 1956, when Harman first postulated the free radical theory of aging, numerous studies have been carried out to test the protective action of antioxidants. One of these protective compounds used in antioxidant therapy ...
