Scientists funded by Masterton's CatWalk Trust have developed a
breakthrough gel that has the potential to improve healing in spinal
cord damage repair.
"This is hug we're very excited the money we spent is looking like
it's going to be extremely beneficial we're buzzing," trust founder
Catriona Williams said.
A former international equestrian representative, Mrs Williams founded
the CatWalk Trust in 2005 after a fall from a horse in 2002 left her a
C6-7 tetraplegic. The group funds research looking for a cure for
spinal cord injuries.
Using $35,000 of funding from the trust, neuroscientists Simon
O'Carroll and Louise Nicholson and cell biologist Colin Green at the
University of Auckland alongside collaborators at University College
London have discovered that preventing cells from talking to one
another for a short period after injury can stop damage spreading while
reducing inflammation and subsequent scar tissue formation.
"Colin said to me he was so excited about this breakthrough that he
couldn't sleep at night, and that's how we feel too," Mrs Williams
said.
The research trio were at Cat Walk's Masterton HQ on Thursday
presenting the culmination of two years of research to a gathering that
included trust patrons Sir Brian Lochore and Aaron Slight.
Dr O'Carroll said the team have developed a gel that can be placed onto
wounds to improve healing and Functional outcomes and are now
developing methods for targeted delivery that can be applied via the
bloodstream or to the spinal column after spinal cord injury.
In parallel, the gel is being developed for spinal cord repair
strategies to overcome surgical constraints and, to move the research
forward, the team are working with the University of New South Wales,
Sydney, he said.
"When a spinal cord is damaged, the Lesion continues to spread during the next 24 hours," Dr O'Carroll said.
"Swelling within the confined space of the spinal column exacerbates
the injury and the accompanying inflammation leads to a scar that poses
a physical barrier to Regeneration of nerve axons.
"Although a number of promising strategies have been developed to
repair spinal cord injury, a major constraint to all of these
approaches is that the intervention itself which creates a new lesion
leading to subsequent injury spread and further scar formation impeding
the repair process.
He said preliminary data supports the contention that a completely new
approach to spinal cord repair is possible by regulating the
communication channels that are themselves increased in number at the
time of injury the Auckland laboratory has developed unique and
specific methods to down regulate these channels expressed after
injury.
"Limiting lesion spread, swelling, inflammation and scarring can
significantly improve the outcome of spinal injury and tissue repair
strategies" Dr O'Carroll said.
Over the next 12 months the Auckland and Sydney teams will continue
proof of concept studies for the systemic delivery protocol and repair
strategies and hope to work together with the CatWalk Trust to drive
these therapies more rapidly towards clinical application.
