Nerve repair discovery
RESEARCHERS at the University of Queensland have identified a molecule essential for regulating the repair of injured nerves that could help people recover from nerve damage.
The finding was made using the nematode worm C. elegans, which has long been studied by researchers for its ability to self-repair nerve cells.
Massimo Hilliard and his team at UQ’s Queensland Brain Institute have identified that the enzyme ADM-4 is an essential protein regulating the molecular glue, or fusogen, needed for nerve repair.
“We have shown that animals lacking ADM-4 cannot repair their nerves by fusion,” Professor Hilliard said.
“ADM-4 must function within the injured neuron to stabilise the fusogen EFF-1 and allow the membranes of the separated nerves to merge.
“An exciting part of this discovery is that ADM-4 is similar to a mammalian gene, opening up the possibility that one day we may harness this process in humans.”
