Neuronal Development: from stem cell to human therapy
Organizer: Pascal Escher
The retina is a model system for neuronal development. This course presents the general anatomy, embryology, biochemistry and electrophysiology of the vertebrate retina (human, mouse and zebrafish), with a special emphasis on the evolutionarily-conserved regulatory transcriptional networks, driving the commitment and the terminal differentiation from a single pool of retinal progenitors towards all the different neuronal and glial cell types. Human retinal dystrophies will be discussed in the context of emerging virus-based gene therapies and stem cell-based therapies.
1. Retinal development and retinal repair
- Anatomy of the eye and the retina.
- Structure and function of retinal cell types: neurons (photoreceptors, bipolar, horizontal, amacrine and ganglion cells), glia (Müller cells), microglia, astrocytes, pigment epithelium.
- Development of the eye and retina: evolution of vision, conservation of retinal development among vertebrates (human, mouse, zebrafish).
- Retinal progenitor cells: pluripotency, patterning, plastic lineages.
- Retinal repair: transplantation, stem cells, in vitro development.
2. Biochemistry and electrophyiology of the retina
- Retinal pigment epithelium: biochemistry, photoreceptor phagocytosis.
- Retinal vitamin A metabolism: rod and cone visual cycle, gene therapy.
- Phototransduction cascade and recovery process.
- Color vision: electrophysiology, phylogeny, gene therapy.
- Retinal circuitry: basic electrophysiology, electroretinography.
3. Transcriptional networks in the vertebrate retina
- Eye- and retina-specific homeobox transcription factors: SOX2, RX (RAX), PAX6, SIX, VAX, CHX10, OTX, CRX.
- Pax6 and eye development: lessons from drosophila.
- Photoreceptor development: OTX, CRX, NRL and nuclear receptors (RAR, RXR, TR, TLX, PNR/NR2E3).
- Genetics of inherited retinal diseases.
- Disease mechanisms of transcription factor-linked retinal dystrophies: Leber congenital amaurosis, Retinitis pigmentosa, Goldmann-Favre syndrome, Color vision defects
