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

Full textGlaucoma is a visual system disorder leading to irreversible blindness and affecting 80 millions people worldwide by 2020. The major risk factor is elevated intraocular pressure leading to progressive retinal ganglion cell (RGC) death from the optic nerve (ON) to visual pathways in the brain. Glaucoma has been reported to share neuroinflammatory mechanisms with neurodegenerative disorders. We therefore hypothesize that mechanisms in central visual pathways may contribute to the spread of glaucoma disease. The aim of the present study was to analyze the neuroinflammation processes that occur from the pathological retina to the superior colliculi (SCs) in a rat model of unilateral ocular hypertension induced by episcleral vein cauterization. By molecular and cell biology methods, we have shown that this animal model is characterized by 1) neuronal damage of CGR from the cauterized eye; 2) the increase in proinflammatory markers in the retina of the cauterized eye, in the retina of the contralateral eye, in the optic nerve and in the superior colliculus and 3) transmission of neuroinflammation in contralateral eye is done mainly by CGR fibers that project into the two superior colliculus. All these data evidence the complex role played by the SCs, in rat, in the propagation of neuroinflammatory events induced by unilateral ocular hypertension

Full textThe enteric nervous system (ENS) is composed of neurons and enteric glial cells. It plays a major role in the regulation of digestive functions. However, the nature of ENS lesions during the majority of digestive disease, as well as the role of inflammation, is poorly understood. The aims of this study were : 1) to develop a routine method allowing characterisation of enteric neuropathies in humans, and 2) to characterise the ENS alterations ex vivo in a human colonic model of shigella infection and identify the mechanisms involved. Firstly, we demonstrated the accuracy of human colonic biopsies to study the ENS, by combining immunohistochemical and Western blot methods. Secondly, we developed an organotypic culture model to study early interactions between the ENS and Shigella flexneri (S. Flexneri), and showed that S. Flexneri induced a neuronal plasticity that was bloked by NOS inhibitor (L-Name), as well as neuronal and glial damages that were prevented by NMDA receptors to glutamate. Beyond ENS alterations, we also noted a major disruption of the intestinal epithelial barrier and identified the key role of the SepA serine protease in these alterations

Full textFTLD is a clinical syndrome mainly characterized by progressive deterioration in behavior, personality and/or language resulting from progressive frontal and temporal degeneration. In addition, movement disorder can also be frequently observed. Given this phenotype variability, FTLD clinical diagnosis remains difficult and uneasy to establish with certainty.The final diagnosis relies on neuropathological examination of the brain, the characteristics of these brain lesions and their molecular basis. Indeed, as many neurodegenerative diseases, FTLD are characterized by the presence of protein aggregates in the affected brain regions. However, in contrast to the well-characterized nature of protein inclusions in Alzheimer’s disease (AD), proteinaceous aggregates in FTLD can be composed of different proteins. Thus, approximatively 40% of FTLD cases display aggregates made of abnormally and hyperphosphorylated Tau proteins and constitute the FTLD-Tau subclass. However, most of FTLD brains are negative for Tau inclusions and exhibit neuronal cytoplasmic and/or nuclear inclusions immunoreactive for transactive response DNA binding protein 43 (TDP-43) and constitute the FTLD-TDP subclass). To a lesser extent, another protein called FUS (Fused in Sarcoma protein) is found in aggregates that are Tau and TDP-43 negative. This subclass is thus named FTLD-FUS. Finally, inclusions negative for Tau, TDP-43 or FUS are observed in rare cases of FTLD and associated with ubiquitin-proteasome system related proteins (FTLD-UPS).Gene mutations also play an important role in FTLD with 30 to 50% of patients reporting a positive family history of FTD and 10 to 15% of patients corresponding to dominantly inherited form. Firstly described are the MAPT mutations. Mutations in the progranulin gene GRN were then found to be the most frequent mutations associated with FTLD. More recently, two studies demonstrated that expanded hexanucleotide GGGGCC repeats in a noncoding region of the chromosome 9 open reading frame 72 (C9ORF72) gene was responsible for a large proportion of FTLD. Less frequently mutations in the valosin containing protein (VCP) gene or charged multivesicular body protein 2B (CHMP2B) gene are also found associated with FTLD.Prior to the discovery of the main molecular actors of FTLD, studies described a partial or total loss of soluble or physiological Tau protein expression in both grey and white matter. This loss of Tau was originally found in a subset of dementia called DLDH for Dementia Lacking Distinctive Histopathology (renamed later FTLD-ni for FTLD with no inclusion). In 2006, most of these cases were reclassified as FTLD-U (presenting with ubiquitin positive inclusions). However, additional investigation with specific regards to this loss of Tau expression has not been reported since Zhukareva et al. in 2003. With the progress in genetics and neuropathology of FTLD, the question of whether this reduction of Tau expression is seldom remains ill-defined.This work takes place in this context whose primary goal was to investigate human brain Tau protein expression in Control, AD, FTLD-Tau, FTLD-TDP-GRN, FTLD-TDP-C9ORF72, sporadic FTLD-TDP and sporadic FTLD-FUS brains using western blot analysis. Remarkably, we demonstrated a huge reduction of all six human brain Tau isoforms only in a subset of FTLD-TDP brains with mutation on the GRN gene. Thus, our data clearly suggest that these specific cases, referred to as FTLD-TDP-GRNltau (for low levels of Tau protein), could be part of the current classification as a distinct entity with more severe synaptic dysfunction and astrogliosis. Beside this, we also performed a comparative proteomic study between the different FTLD sub-classes in order to find common physiopathological mechanisms

Full textAn increasing number of arguments suggest a close and complex link between cholesterol metabolism and neurodegenerative diseases, particularly with Alzheimer’s disease. Normal ageing is associated with a decrease of brain cholesterol content. Conversly, accumulation of brain cholesterol is associated with several neurodegenerative diseases (Huntington disease, Parkinson disease, epilepsy, Niemann Pick C disease, Alzheimer’s disease). Moreover, close connections exist between molecular physiopathology of AD and that of Niemann Pick, a disease of cholesterol homeostasis. Altogether, these results suggest that cholesterol overload might play a role, as an initiating factor for the development of AD.In the brain, cholesterol metabolism is tightly controlled. In adults, cholesterol is mainly synthetized by astrocytes, then shuttles to neurons where it is used. All cholesterol excess must be eliminated. Cholesterol cannot cross freely the blood-brain-barrier. To be metabolized, brain cholesterol must be converted in 24-hydroxy-cholesterol by the cholesterol-24 hydroxylase enzyme, coded by CYP46A1 gene. The objective of my PhD project was to determine if cholesterol accumulation in vivo in hippocampal neurons, a region early involved in AD pathology, could trigger neurotoxic processes with biochemical and neuropathological modifications close to what is observed in AD. Cholesterol overload in vivo was induced by inhibiting cholesterol 24-hydroxylase enzyme activity, using an RNA interference strategy. Stereotactic injection of an AAV5- shCYP46A1 vector in the stratum lacunosum moleculare of the hippocampus led to significant and rapid (as soon as 3 weeks after injection) inhibition of the Cyp46a1 gene in the hippocampus with an absence of RNA interference off-target effect. This inhibition was associated with a decrease of 24-hydroxycholesterol content and an increase of the cholesterol content. In response to this cholesterol excess, cell control mechanisms were initiated leading to decrease import and increase export of cholesterol, accompanied with an increase of phosphatidylcholine content to restore a physiological ratio of phospholipide/cholesterol. However, major accumulation of cholesterol led to neuronal death with activation of caspases 9 et 3, suggesting an apoptotic process. The cholesterol overload drives to an endoplasmic reticulum stress, with activation of the unfolded protein response (UPR) and expression of spliced XBP1, ATF6, GRP78, phosphorylated PERK, CHOP and caspase 12. These modifications were associated with phosphorylation of GSK3 (Tyr 216) and tau (Thr 231) proteins. In parallel, cholesterol accumulation led to increased expression of Rab5 (early endosome marker) and relocalization of APP in rafts domains associated to activation of amyloid pathway (production of -CTF fragments and A42 peptides). Lipidomic analysis showed an increase of ceramides and gangliosides content. All these modifications were associated with neuronal death 4 weeks after injection and astrocytosis, leading to an EEG theta rhythm accelerated to beta frequencies, memory deficits and hippocampal atrophy. In a mouse model of Alzheimer disease, the APP23 mouse, cholesterol accumulation led to major aggravation of the phenotype, with increased production of A peptides, occurring of tau phosphorylation and UPR response, leading to accelerated neuronal death. Altogether, these results suggest a direct link between cholesterol accumulation in the brain and Alzheimer’s disease. Brain cholesterol accumulation could seed the sows to the development of Alzheimer’s pathology. Reducing cerebral cholesterol could thus be a relevant therapeutic strategy to prevent the development, or at least slow down the evolution of the pathology in Alzheimer’s disease

Full textBrain-Machine Interfaces consist in the direct interfacing of a nervous tissue onto an electronic device. In vitro interfaces are expected to outperform computer calculations by achieving parallel information processing within neural networks. Applying electrical stimulations, in vivo brain-machine interfaces aim at assisting, rehabilitating or repairing cognitive or sensory-motor functions. Either for data analysis or information transfer, the main challenge of these interfaces relies in the cell/material interactions. Particularly in the case of retinal prosthetics, the current resolution remains insufficient to allow patients to read complex texts, to perform locomotion tasks in a complex environment and recognize faces. However, the first clinical trials showed encouraging results in blind patients, even though the restored visual acuity is still below legal blindness. During my PhD, we have worked on the biocompatibility of new semi-conducting materials, the functionalization and configuration of electrodes for retina-machine interfaces, both in vitro and in vivo. The first part of my work consisted in reconstructing a retinal neuronal network on a multielectrode array. We propose a novel technique to specifically address neuronal populations on pre-defined electrodes on an array, using either a specific antibody or lectine. This selection is performed from a mixed cell suspension even when selected neurons represent a minor population. This possibility to reconstruct a retinal neuronal network opens new perspectives for studying the formation and physiology of this neuronal network. The second topic of my work concerned the development of new approaches to increase the resolution and long-term stability of retinal implants. First, we demonstrated the biocompatibility of two semi-conducting carbon-based materials, graphene and diamond, with retinal neurons. These neurons could develop long neurites directly on the tested materials without any protein coating. By contrast, glial cells showed a clear preference for peptide-coated surfaces. Prior to integrating these materials on in vivo implants, we have shown the advantage of 3D structures to focalize stimulation currents onto neurons filling the implant cavities or wells. The diamond coating at the surface of these 3D soft implant prototypes does not seem to induce any major inflammation in the retina of blind rats. These works open new perspectives in the field of brain machine interfaces, neuroprostheses, with a specific emphasis on visual rehabilitation confirming the interest of diamond and graphene and proposing new strategies of cell/electrode or tissue/implant interfaces

Full textCerebral palsy (CP) corresponds to various motor, sensory and cognitive disorders related to white matter damage (i.e. periventricular leucomalacia, PVL) often occurring after perinatal hypoxic-ischemic events. To reproduce PVL in rodents, we used a prenatal ischemia (PI) that induces white and gray matter damage. The ischemic rats exhibit visual-spatial cognitive deficits and hyperactivity, as observed in patients with CP, related to lesions of entorhinal, prefrontal and cingular cortices. Only mild locomotor disorders are induced by PI, associated to signs of spasticity, along with anatomical and functional degradation in the primary somatosensory cortex (S1), while the primary motor cortex (M1) remains unchanged. Thus, PI recapitulates the main symptoms found in children born preterm. Abnormal spontaneous movements (i.e. general movements) observed in infants who develop CP later on suggest that abnormal sensorimotor experience during maturation is key in the development of this catastrophic disease. The combination of a sensorimotor restriction (SMR) and PI in animal induces fewer cognitive deficits but still hyperactivity. Such a combination leads to severe postural and motor disorders, and spasticity, associated with musculoskeletal pathologies, as observed in patients with CP. In addition to motor disorders, drastic topographical disorganization of cortical maps in S1 and M1 suggest a major dysfunction of sensorimotor loops

Full textThe role of p53 family members in neuronal apoptosis has been suggested by many studies. However, the mechanisms by which this pathway is regulated remain poorly known. We undertook to study the regulation of two components of the p53 regulatory pathway: MDMX and p73 (with its long and short isoforms, TA and DN respectively). To this aim, we cultured primary neurons in which we induced apoptosis via different pathways (DNA damage, loss of electric activity, excitotoxicity and APP stimulation). Our results show that these stresses induce loss of MDMX and DNp73. We demonstrate that those factors undergo degradation via phosphorylation at specific sites. Furthermore, overexpression of either MDMX or DNp73 partially restores neuronal viability after neurotoxic treatments. Our results show that MDMX and DNp73 are anti-apoptotic factors that inhibit not only p53, but E2F1 (for MDMX) and Tap73 (for DNp73) activity as well

Full textNeural circuit dynamics need to be elucidated for understanding neurological and psychiatric disorders such as Parkinson's disease and schizophrenia. While this is classically studied in vivo or ex vivo, micro-technological approaches permit “brain-on-chip” models recapitulating some intrinsic neuronal network properties. In this study, parameters of cortico-striatal connection were monitored. Glutamatergic neuronal network activity was monitored using calcium imaging. Dopamine and Dopaminergic receptor 2 agonist decreased firing frequency and disrupted striato-striatal synchrony. Then, we demonstrated that both acute and chronic alterations of cortical neurons activity led to impairment of striatal survival through trans-synaptic degeneration. In psychiatric diseases, network rhythm alterations do not lead to neuronal death but to behavior disorders. To study how those alterations appeared, we investigated the impact of DISC-1 expression modulation on the establishment of cortico-striatal network and its activity. Alteration of DISC-1 expression led to deficits in striatal differentiation processes and seemingly did not drive network rhythms variation. Interestingly, DISC-1 overexpression experiments showed its aggregation in stress granules concomitant with an ability to recruit others proteins involved in synaptic transmission and neuronal plasticity. These results seem to show that DISC-1 could be involved in degenerative processes and not only in psychiatric diseases. The present data demonstrate that cortico-striatal networks reconstructed in a microfluidic environment present characteristics similar to in vivo cortico-striatal networks
