Thomas Becker is the director of the MSc by Research in Integrative Neurocience.
Zebrafish have an amazing capacity for central nervous system (CNS) regeneration. They regain function after complete lesions of the spinal cord. Such lesions in mammals are not repaired and functions are permanently lost.
Evidence suggests that ependymo-radial glial cells (ERGs) in the spinal cord are crucial for the regeneration process by generating new neurons and facilitating repair of axonal connections (for review see: Becker and Becker, 2015, Neuronal Regeneration from Ependymo-radial Glial Cells: Cook, Little Pot, Cook! Developmental Cell 32(4):516-27). Recent BBSRC funding allows us to ask two fundamental questions:
- How can zebrafish replace lost neurons from adult stem cells?
- What are the signals that promote neuronal regeneration?
To address these questions, we study gene regulation in ERGs that leads to reprogramming of quiescent ERGs for neurogenesis after a lesion, focussing on histone acetylation and we analyse immune signals as mediators of the regenerative response.
By analysing development and regeneration of important cell types in the zebrafish we hope to gain insight into fundamental developmental and regenerative mechanisms in the CNS, and to ultimately increase our understanding of human conditions, such as spinal cord injury. We closely collaborate with the group of Catherina Becker.
