The alpha-synuclein proteostasis network and its translational applications in Parkinson's disease

2 weeks 2 days ago
Parkinson's disease (PD) is a debilitating neurodegenerative condition that results in a loss of mobility and muscle control. A neuropathological hallmark of PD is the presence of aberrant inclusions, known as Lewy pathology, of which α-synuclein (α-Syn) is a major component. The accumulation of α-Syn may be due to an imbalance in the proteostasis system regulating α-Syn. To investigate this hypothesis, we delineated the proteostasis network (PN) of α-Syn in the human substantia nigra at the...

The role of glutathione in cognition, cognitive effort, and cognitive endurance in young and older adults

2 weeks 2 days ago
Glutathione (GSH) is an abundant antioxidant that protects against endogenous and exogenous toxic agents. The evidence over the relationship between GSH and cognitive integrity during aging is still scarce. In this study we investigated the relationship between GSH and cognitive integrity, cognitive effort and sustained cognitive effort. Second, we explored whether GSH modulation is related to other physiological properties such as blood oxygenation (BOLD response) and to brain excitability...
