Scientists in Scotland on the way to discovering the cause of long term disability in MS

Scientists in Scotland may be on the way to discovering the cause of
long term disability in people with multiple sclerosis (MS).

New research carried out at the University of Aberdeen in Scotland, led
by Professor Chris Linington, showed that some people with MS have
specific antibodies (a type of immune molecule) which attack nerve
fibres.

The newly identified antibodies recognise and attack a protein called
neurofascin-186 which makes up part of the nerve fibre. Higher levels of
these antibodies were discovered in a small study of people with MS who
have a particularly degenerative type of MS.

Researchers are now planning a larger study and if further research
showed the antibody to be responsible, it may be possible to remove
these antibodies from the blood of people with MS to slow disease
progression.

Professor Linington said 'I am particularly encouraged because there are
already treatments available for other antibody mediated conditions.
These type of therapies could be very rapidly translated and applied to
MS if we confirm our findings'

Millions of nerve fibres are responsible for transmitting messages from
our brain to the rest of our body and these nerves are covered in a
protective coating called myelin which wraps in bundles around nerve
fibres. The gaps which exist between these bundles are very important to
allow transmission of nerve impulses along nerve fibres. The neurofascin
antibodies can attack the nerve fibres between these gaps in the myelin.

In a rat model of MS the attacking antibodies interrupted nerve impulse
transmission and worsened disease symptoms by damaging nerve fibres.
Dr Laura Bell, research communications officer at the MS Society, said:
'Nerve fibre loss is thought to be the primary cause of long term
disability in MS though little is known about what causes that loss.
This early research provides potential insight into the process and I
look forward to seeing the results of the next stage of the study.'
