During neuronal differentiation, axonal elongation is regulated by both external and intrinsic stimuli, including neurotropic factors, cytoskeleton dynamics, second messengers such as cyclic adenosine monophosphate (cAMP), and neuronal excitability. Chloride intracellular channel 1 (CLIC1) is a cytoplasmic hydrophilic protein that, upon stimulation...
Chloride intracellular Channel 1 (CLIC1) is a metamorphic protein that changes from a soluble cytoplasmic protein into a transmembrane protein. Once inserted into membranes, CLIC1 multimerises and is able to form chloride selective ion channels. Whilst CLIC1 behaves as an ion channel both in cells and in artificial lipid bilayers, its structure in...
Ataxin 1 (ATXN1) is the protein involved in spinocerebellar ataxia type 1, one of nine dominantly inherited neurodegenerative diseases triggered by polyglutamine expansion. One of the isolated polyglutamine tracts properties is to interact with lipid bilayers. Here we used a multidisciplinary approach to test whether one of the mechanisms responsib...
Oxidative stress, characterized by overproduction of reactive oxygen species (ROS), is a major feature of several pathological states. Indeed, many cancers and neurodegenerative diseases are accompanied by altered redox balance, which results from dysregulation of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase. In this review, we consi...
The Alzheimer's disease (AD) brain is characterized by plaques containing beta-amyloid (Abeta) protein surrounded by astrocytes and reactive microglia. Activation of microglia by Abeta initiates production of reactive oxygen species (ROS) by the plasmalemmal NADPH oxidase; the resultant oxidative stress is thought to contribute to neurodegeneration...
