In view of the increase in the aging population and the unavoidable parallel increase in the incidence of age-related neurodegenerative diseases, a key challenge in neuroscience is the identification of clinical signatures which change with age and impact on neuronal and cognitive function. Early diagnosis offers the possibility of early therapeutic(More)
There is a well-established literature indicating a relationship between iron in brain tissue and Alzheimer's disease (AD). More recently, it has become clear that AD is associated with neuroinflammatory and oxidative changes which probably result from microglial activation. In this study, we investigated the correlative changes in microglial activation,(More)
Age is characterized by deficits in synaptic function identified by decreased performance of aged animals in spatial learning tasks and reduced ability of animals to sustain long term potentiation (LTP). Several cellular and molecular events are correlated with these deficits, many of which are indicative of age-related neuroinflammatory and oxidative cell(More)
The NLRP3 inflammasome forms in response to a diverse range of stimuli and is responsible for the processing and release of interleukin-1β (IL-1β) from the immunocompetent cells of the brain. The pathological peptide of Alzheimer’s disease, amyloid beta (Aβ), induces formation of the NLRP3 inflammasome in a manner dependent on the family of proteases,(More)
