Developmental Neuroscience - Regeneration

Developmental Neuroscience - Regeneration
Current Neuro-development projects involve:
- Investigation of glial-neuronal interactions in the developing nervous system.
- Elucidation of spinal cord radial glial cell development and determination of the lineage relationships among different types of neuroepithelial cells in the spinal cord.
- Gene expression profiling in neuroepithelial stem and progenitor cells during development and in the adult CNS to elucidate mechanisms underlying fate decisions, differentiaton and phenotypic diversity.
- Spatial and temporal patterns of oligodendrogliogenesis and myelination in vivo.
- Investigation of the expression of the neurotrophic proteins GDF5 and GDNF, their receptors and intracellular signalling mechanisms in the developing and adult brain.
- Examination of the development of midbrain dopaminergic neurons, including gene expression profiling using microarray technology and studies on phenotypic changes which occur during specification, maturation and differentiation of these neurons.
- Investigation of the effect of inflammation on neurogenesis in the embryonic and adult hippocampus.
- Elucidation of the migration patterns of newly generated astrocytes and oligodendrocytes
