Full textRetinitis pigmentosa is an hereditary retinal dystrophy involving degeneration of photoreceptors leading to blindness and for which there is currently no treatment. The most frequent cause of autosomal dominant forms of the disease is a point mutation in the rhodopsin gene (RHO). Therapeutic strategy should both suppress mutant protein expression and restore that of the normal one to physiologic level to prevent photoreceptor degeneration. My PhD project was to repair RHO pre-mRNA by SMaRT (Spliceosome Mediated RNA Trans-splicing) technology. This implies to introduce by gene transfer into the target cell an exogenous RNA, called PTM for Pre-mRNA Trans-splicing Molecule. This one was able to promote a splice reaction in trans, leading to the replacement of the mutated exons. We designed 20 different PTM and obtained in vitro a maximum trans-splicing rate of 40% after transient co-transfection of PTM and RHO constructs in HEK293T cells. We then created WT or mutated RHO stable expression cell lines by lentiviral transduction. Mutation induced retention of the protein into the cytoplasm, while the WT RHO was localized to the plasma membrane. We observed that the PTM transfection in the mutated RHO cell line induced trans-splicing, which was able to partially restore localization to the plasma membrane of repaired RHO. We then tested trans-splicing in vivo in mRho+/- RHO P347S+ mice, a humanized heterozygous mouse model of retinitis pigmentosa. After subretinal injection of AAV2/8-bRho-PTM we observed that trans-splicing occurred in vivo. Unfortunately we did not observe by SD-OCT (a technology that we improve in this project) any rescue of the degenerative phenotype

Full textRetinitis pigmentosa (RP) is an inherited retinal diseases characterized by a loss of photoreceptors. We focused specific forms of autosomal dominant RP with mutations in the rod visual pigment RHODOPSIN, the ubiquitous splicing factor PRPF31 and the transcription factor involved in the development of photoreceptors NR2E3. Fibroblasts from skin biopsies of patients were reprogrammed into iPS cells by a non-integrative approach. After stabilization of iPS cell lines, we verified their pluripotency property and the absence of karyotype abnormalities. Based on the retinal differentiation protocol, iPS cells carrying a mutation in the RHODOPSIN gene have been differentiated in the photoreceptor lineage. Our results showed that the photoreceptors expressing the mutated form of RHODOPSIN summarizing the process of degeneration observed in RP patients. We show that retinal pigment epithelium (RPE) cells derived from iPS cells carrying a mutation in the PRPF31 gene lack basal membranes and have cell adhesion disorders. Consequently, their phagocytic activity is disturbed, suggesting that a malfunction of the RPE could be the primary step of the development of RP caused by mutation Cys294X in the PRPF31 gene. The models developed from specific-patient iPS cells have enabled us to better understand the processes underlying the pathogenesis of some RP. These models associated with screening protocols could be used to evaluate the efficacy and toxicity of new pharmacologic compounds but also used to validate new gene therapy approaches

Full textThe use of bioinformatics by its integrative power has become essential to face the arrival of high throughput data, produced by techniques often characterized by the suffixes “omics”, such as genomics, transcriptomics, proteomics. . . In this context, we have developed RetScope, a platform dedicated to the automated analysis of eukaryotic sequences, allowing a precise and complete characterization of individual sequences taking to an improved view of biological processes at the “ome” level (genome, transcriptome, proteome). Multiple strategies involving various biological contexts with different organisms (man, mouse, zebrafish, etc) demonstrated the robustness of RetScope for analysing data obtained through techniques like DNA chips, Differential Display, Expressed Sequence Tag, etc. During a collaboration with the laboratory of Cellular and Molecular Physiopathology of Retina, RetScope has been used to analyse transcriptomic data of the rd1 mouse, a model of the human retinitis pigmentosa. These studies led to a kinetic and spatial model consisting of four steps providing explanations to the molecular mechanisms leading to photoreceptor degeneration. Furthermore, we performed a sequence/structure/function analysis of two trophic factors, RdCVF1 and 2 (Rod derived Cone Viability Factor), excreted by rods with effects on cone viability. These paralogous genes have a similar genic organization that is strictly conserved in all Vertebrata and Nematoda. These factors open major therapeutic perspectives for cone degeneration diseases, such as retinitis pigmentosa and Age-related Macular Degeneration (AMD)

Full textThe possibility that survival of cone photoreceptors depends on the presence of rod photoreceptors was previously demonstrated by transplantation of rod-enriched photoreceptor layers into the sub-retinal space of the retinal degeneration rd1 mouse, a model of Retinitis Pigmentosa (RP). In vitro experiments suggested that rod effects upon cones were mediated by soluble factors. Identification of these factors could enable us to design new therapies in the case of human RP, inherited diseases where loss of rods, the principal cellular sites of genetic mutations, trigger secondary cone degeneration leading to irremediable blindness. In order to characterise soluble factors involved in survival of rd1 mouse cones, we validated a functional assay for cone survival studies: chick embryonic retinal cell cultures. We aimed at determining the nature and the weight of these soluble factors by using both the enriched cone functional assay and rd1 mouse explants cultures. Dialyses and heating of conditioned medium promoting cone survival suggested thermolabile molecules of molecular weight superior to 25kDa. Similarly, glial cell line-derived neurotrophic factor (GDNF), a 30 kDa protein exhibiting neuroprotective effects on a range of neural types, has been previously shown to protect photoreceptors in different experimental models. It was tested upon chick cone-enriched and rat rod-enriched retinal cell cultures, and show to have a direct effect upon rod but not cone photoreceptor survival. While awaiting systematic screening of soluble factors promoting cone survival, these results establish the foundations for further studies on candidate neurotrophic factor testing

Full textMy Ph. D. Work consisted of the research of the genetic bases of rétinopathies in the dog, like model of the corresponding human diseases: pigmentary retinites at the Man with a prevalence of 1/3600 which end in blindness. The canine homologous of pigmentary retinites are the progressive atrophies of retina (PRA). The interest of the canine model lies in the history of the dog and the races which makes that within a race, only one form of PRA segregates and thus facilitates genetic research. My main subject dealt with a PRA in Border Collie. A pedigree of 200 dogs was made up and a recessive transmission related to X chromosome was shown. A linkage analysis permitted the identification of a new 12 Mb locus in which metabolic candidate genes had been sequenced. The Ph. D. Also presents a work on another retinopathy and genetic researches on anomalies of the development
