Full textThe overlap of neurotoxic mecanisms involved in prion diseases and synucleinopathies, and the concomitant detection of pathological forms of prion and α-synuclein in a same neurodegenerative disease, raise questions about the existence of potential relationship between α‐synuclein molecular alteration and prion diseases. First, we developed monoclonal antibodies by immunizing mice presenting a spontaneous deletion of the α-synuclein gene with human recombinant α‐synuclein. Then, we characterized the molecular alterations appearing jointly to clinical signs during the aging of a transgenic mouse model of synucleinopathies (TgM83), overexpressing human A53T α‐synuclein. Then, an approach routinely done in the field of prion was used to trigger a synucleinopathy alongside a prion disease. For this purpose, TgM83 mice were inoculated intracerebrally by three different prion strains : transmission of H-type bovine spongiform encephalopathy allows the onset of a prion disease concomitantly to the α‐synuclein pathology developed by the TgM83 mouse model. Finally, intracerebral inoculation of TgM83 mice with brain homogenates from symptomatic mice affected by a synucleinopathy triggers an important acceleration of the α‐synuclein pathology, resulting in the early onset of motor clinical signs associated with molecular alterations of α-synuclein. These data suggest that α-synuclein alterations can be experimentally transmitted from one mouse to another, supporting the idea that, far from being confined to the transmissible spongiform encephalopathies, the « prion-like » propagation of misfolded neuronal proteins might occur in synucleinopathies

Full textTransmissible spongiform encephalopathies (TSE) are characterized by the accumulation of a protein called PrPSc in the central nervous system of affected individuals. According to the prion hypothesis, PrPSc itself is the infectious agent in TSE. Whether biological (in vivo) and biochemical (study of the properties of PrPSc) prion strain typing can reflect the whole diversity of TSE agents remains doubtful. Within this context, the first part of our work consisted of establishing the biochemical phenotype of PrPSc in a large panel of Creutzfeldt-Jakob disease (CJD) isolates that had been previously classified according to genetic and clinico-pathological criteria. We identified four biochemical subgroups that only partially correlated with the pre-established subclassification and could therefore represent different prion strains. In the second part of our work we looked into the ability of scrapie isolates to propagate into murine transgenic models expressing PrPC of various species. We demonstrated that passage across the porcine and bovine species barriers by the atypical scrapie agent led to the emergence of new prions, including the agent of the bovine spongiform encephalopathy. Furthermore, we managed to transmit several classical scrapie isolates to two different transgenic mice strains expressing human PrP. In one of these models, the biochemical signature of the propagated agent was similar to that of sporadic CJD isolates

Full textTransmissible spongiform encephalopathies (TSEs) are fatal neurodegenerative diseasesoccurring in animals and humans for which no ante-mortem diagnostic test in biological fluidsis available. In such pathologies, detection of the pathological form of the prion protein (i.e.,the causative factor) in blood is difficult. Identification of new biomarkers implicated in thepathway of prion infection is relevant. In this context, our objective was to find a proteicprofile correlated to TSEs. We used a well-known TSE model: scrapie in sheep breeding, amass spectrometry technology easy-to-use for proteic profiling: SELDI-TOF MS and abiological fluid: serum. First, experimental tools have been developed and optimized. Thesetools were evaluated for their discriminating potential of control sheep and animals with earlyor late phase scrapie using a large number of serum samples (fractionated or not). Then, usingthe SAM statistical method, potential low molecular weight biomarkers were selected. Amongthese biomarkers, a protein signature pattern was identified; it can discriminate between earlyphase scrapie and control sera (sensitivity of 87% and specificity of 90%). One of theseproteins was identified as a fragment of transthyretin and evaluated as a biomarker using aSELDI-TOF MS kinetic study of sera from scrapie infected Syrian hamsters. This biomarkerwas also confirmed by western blot analysis and ELISA quantitation. Finally, a cohort of freescrapiesheep permits to validate the diagnostic potential of the candidate biomarkers

Full textTransmissible spongiform encephalopathies (TSE) are a group of mammalian neurodegenerative disorders characterised by brain accumulation of an abnormal, insoluble and protease-resistant isoform (PrPsc) of host-encoded cellular prion protein (PrPc). These diseases can be inherited, spontaneous or transmitted from host to another within and between species. Since “Mad-Cow disease” crisis, TSE has been becoming a high priority of governments because a large people are exposed to a potential risk of infection. Indeed, the presence of pathogen agent in blood during the long and silent incubation period and the current lack of a reliable test to identify individuals incubating the disease, induces that transmissibility by blood transfusion, transplantation or reuse of surgical instruments should be possible. In order to contribute of the prion disease presymptomatic diagnosis, we have developed a method that could detect very low level of PrPsc in tissues and biological fluids. To do this, we first demonstrated the precipitation properties of streptomycin and its usefulness to explore the early stages of infection. Then, we proved the ability of grafted calixarenes to capture PrP, before highlighted that their association could be able to diagnose TSE infection in all tissues and in all species tested. Thus, this work provides both technical tools to study early stages of prion diseases and a diagnostic protocol which should allow the development of a kit assay to detect PrPsc in biological fluids during the incubation period of TSE
