Abstract
In
the last several years, relevant progress has been made in our
understanding of the transcriptional machinery regulating
CNS repair after acute injury, such as following trauma or
stroke. In order to survive and functionally reconnect to the synaptic
network, injured neurons activate an intrinsic rescue
program aimed to increase their plasticity. Perhaps, in the attempt
to switch back to a plastic and growth-competent state,
post-mitotic neurons wake up and re-express a set of transcription
factors that are also critical for the regulation of their
younger brothers, the neural stem cells. Here, we review and discuss
the transcriptional pathways regulating both axonal
regeneration and neurogenesis highlighting the connection between the
two. Clarification of their common molecular substrate may
help simultaneous targeting of both neurogenesis and axonal regeneration
with the hope to enhance functional recovery following CNS
injury.
