Full textNeurofibrillary tangles (NFTs) are classic lesions of Alzheimer's disease (AD). NFTs are bundles of abnormally phosphorylated tau, the paired helical filaments. The initiating mechanisms of NFTs and their role in neuronal loss are still unknown. Accumulating evidence supports a role for the activation of proteolytic enzymes, caspases, in neuronal death observed in AD brains. Alterations in tau phosphorylation and tau cleavage by caspases have been previously reported in neuronal apoptosis. However, the links between the alterations in tau phosphorylation and its proteolytic cleavage have not yet been documented. Here, we show that during staurosporine-induced neuronal apoptosis, tau first underwent transient hyperphosphorylation which was followed by dephosphorylation and cleavage. Tau dephosphorylation and cleavage were blocked by inhibiting protein phosphatase 2A. These experiments indicate that tau dephosphorylation precedes and is required for its cleavage and degradation. Prior tau dephosphorylation by lithium enhanced tau cleavage and sensitized neurons to staurosporine-induced apoptosis. Moreover we show that exposure of cultured cortical neurons to lithium decreased tau protein levels. This decrease was not linked to the activation of proteolytic processes or to neuronal loss, but was associated with the reduction in tau mRNA. We propose that the absence of cleavage and degradation of hyperphosphorylated tau may lead to its accumulation in degenerating neurons. We also suggest that lithium may exert its neuroprotective action by down regulating tau levels

Full textMultiple sclerosis (MS) has long been regarded as an inflammatory demyelinating disorder of the white matter. But post-mortem studies have recently shed light on the extensive involvement of the grey matter (GM). Neuronal damage, characterized by synaptic and dendritic loss as well as neuronal apoptosis, is thought to be a major substrate of physical and cognitive deterioration in MS patients. There is a crucial need for new imaging techniques able to specifically assess neuronal damage in MS. Using positron emission tomography (PET) with [11C]flumazenil ([11C]FMZ), an antagonist of the central benzodiazepine site located within the GABAA receptor, and a non-invasive quantification method, we measured and mapped neurodegenerative changes in the GM of patients with MS at distinct disease stages. A cohort of 18 MS patients was compared to 8 healthy controls and underwent neurological and cognitive evaluations, high-resolution dynamic [11C]FMZ PET imaging and brain MRI. PET data were evaluated using a region of interest and a surface-based approach. [11C]FMZ binding was significantly decreased in the cortical and subcortical GM of MS patients compared to controls. These changes were significant in both progressive and relapsing-remitting forms of the disease and correlated moderately with white matter lesion load. [11C]FMZ cortical binding was also associated with cognitive performance. This pilot study is the first to quantify in vivo the neurodegenerative changes occurring in MS. Our results show that PET with [11C]FMZ could be a promising and sensitive quantitative marker to assess and map the neuronal substrate of GM pathology in MS

Full textIntractable temporal lobe epilepsy may be consecutive to the loss of neurons in the hippocampus. In this brain area, neurodegeneration may be induced by inflammatory processes. Using a rat model of epileptogenesis, we characterized the inflammatory response in the hippocampus, that we show to precede neurodegeneration. We evidenced a high induction of proinflammatory cytokine concentration, mainly in cells corresponding to activated microglia and to monocytes which infiltrated the hippocampal parenchyma. Degradation of heparan sulfate chains present at the surface of monocytes by neuronal heparanase may promote their progression in the brain parenchyma. Blockade of the linkage site of heparanase on heparan sulfate chains could reduce brain infiltration of monocytes and then prevent neurodegeneration associated to epilepsy
