MS research ‘Holy Grail’: Diabetes drug helps repair damaged myelin

Please note: The current Coronavirus Covid-19 pandemic is fast moving, and reactions to it seem to update not just day-by-day but minute-by-minute. Obviously, this site was not designed to bring you the very latest developments in a ‘breaking news’ story such as this. Instead, this site will continue to include news and opinions relating to major events, policy changes, and so on.

Great news on the research front is that a diabetes drug potentially has a vital role to play in the fight against multiple sclerosis.

A study, part-funded by the UK’s MS Society, has revealed that the drug pioglitazone could help through its ability to protect nerves from damage.

Those of us living with MS are well aware that the protective myelin coating around our nerves has been damaged. and made our nerves vulnerable to further damage. In time, this causes disability.

Now, the MS Society says that, for the first time, researchers at the University of Edinburgh have shown nerves have the natural ability to boost their energy supplies after being damaged – and that pioglitazone can help them do that.

The MS Society explains: “They (the nerves) do this by moving mitochondria (the energy powerhouse of cells) to the damaged part of the nerve fibre. The researchers called this process ARMD (axonal response of mitochondria to demyelination).”

Dr Don Mahad, from the MS Society Edinburgh Centre for MS Research, said: “Although our understanding of MS has vastly improved over the last few decades, new therapies still do not protect nerve fibres. Such protection is the Holy Grail in MS treatment – not only for the relapsing form of MS, which has various options available, but for progressive forms too, where treatment continues to lag behind.

Incredibly important discovery

“Our discovery shows that nerves respond to myelin damage by increasing the movement of energy producing mitochondria to the area of damage – a response which we term ‘ARMD’. Remarkably, we were able to enhance ARMD and protect these vulnerable nerves using the readily available diabetes drug pioglitazone. We believe this is an incredibly important discovery, which could finally bridge the gap between myelin damage and myelin repair.”

So, an exciting development, but what does this mean for you and I – people with MS? Let’s not get carried away, although potentially a giant leap forward, research always takes time to bear fruit.

This research was done in mice and in cells grown in a dish, so early days. But pioglitazone is also being tested in clinical trial of people with progressive MS in the US (called TRAP-MS), to see whether it can target the immune system attacks on myelin.

Dr Emma Gray, MS Society assistant director of research, said: “This represents another important stride towards our goal of stopping MS – and we believe that MS treatment could in the near future look completely different.

“People with MS will be prescribed a combination of therapies that work on every aspect of the condition: stopping immune attacks and relapses, protecting nerves from damage, and regenerating lost myelin. It will mean no one needs to worry about their MS getting worse.

“Currently, there are no effective neuroprotective therapies available for MS, but Dr Mahad’s research demonstrates we are getting closer – and finding treatments for everyone with MS is now a very real pros pect.”

Note that “everyone with MS”. Potentially, this could be a treatment for all types of MS.
