Inflammation and iron accumulation are present in a variety of neurodegenerative diseases that include Alzheimer's disease and Parkinson's disease. The study of the putative association between inflammation and iron accumulation in central nervous system cells is relevant to understand the contribution of these processes to the progression of neuronal death. In this study, we analyzed the effects...
Hallmarks of idiopathic and some forms of familial Parkinson’s disease are mitochondrial dysfunction, iron accumulation and oxidative stress in dopaminergic neurons of the substantia nigra. There seems to be a causal link between these three conditions, since mitochondrial dysfunction can give rise to increased electron leak and reactive oxygen species production. In turn, recent evidence indicates...
Iron is an essential element for life on earth, participating in a plethora of cellular processes where one-electron transfer reactions are required. Its essentiality, coupled to its scarcity in aqueous oxidative environments, has compelled living organisms to develop mechanisms that ensure an adequate iron supply, at times with disregard to long-term deleterious effects derived from iron accumulation...
