Suppressor of Cytokine Signalling-2 (SOCS2) and its role in neuronal development and function

Funded Activity Summary

Injury to the brain or spinal cord at present often results in permanent damage, such as paralysis, which is largely due to a failure of neurons to regrow at the injury site. In order to overcome this, we are trying to find ways of making new neurons grow, either from stem cells present in the nervous system or transplanted from cells grown in tissue culture. However, little is known about how a neural stem cell decides to become a neuron or another cell type, such as a glial cell and so we are examining factors which influence this process, which is called differentiation. Growth factors are important mediators of this process and suppressor of cytokine signalling (SOCS) proteins are important in determining how cells respond to growth factors. The overall aims of this project are to determine the role that SOCS genes and in particular, SOCS2 play in neural stem cell differentiation into neurons and glia, neuron process outgrowth and neuronal and glial injury responses in the nervous system. This will be examined in normal cells and cells which over-express or do not express SOCS2 genes. Understanding the biology of neural growth factor responsiveness may eventually allow us to devise therapeutic strategies for use following brain-spinal injury or disease, including generation of neurons from stem cells.
