Redox Status and Aging Link in Neurodegenerative Diseases 2015
Description
In cells there is a balance in redox state that is in large part because of the production of reactive oxygen/reactive nitrogen species (ROS/RNS) and the antioxidant systems that detoxify them. The ROS/RNS at low level have physiological roles as signaling molecules in various cellular and developmental processes. However, the increase in the production of these species and/or the decrease in the antioxidant capacity can lead to perturbation of the redox balance, causing oxidative/nitrosative stress which ultimately leads to cell death. Aging and age-related neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and Huntington’s are known to be associated with increased oxidative stress. Different reports have suggested that an increase in oxidative stress may lead to cognitive impairment during aging; additionally, increasing evidence also suggests that ROS may act as signaling molecules in processes underlying cognition. Understanding of the impact of impairment in the balance of antioxidant defense and ROS/RNS generation as common factors in aging and neurodegenerative diseases, as well as the mechanisms that are involved, will lead to a better comprehension of several processes related to aging and neurodegeneration biology.
Since developments in this field have been rapid, we invite investigators to contribute original research articles as well as review articles that address the progress and current standing in this vast field of biology.
