People with epilepsy could be helped by new research into the way a key molecule controls brain activity during a seizure.
Scientists at Edinburgh University have identified the role played by a protein - called BDNF - and say the discovery could lead to the development of new drugs.
They analysed the way cells communicate when the brain is most active, such as in the seizures.
They found the BDNF molecule has the harmful effect of blocking a process known as activity-dependent bulk endocytosis (ABDE). By doing this during a seizure, BDNF increases the release of neurotransmitters and causes heightened electrical activity in the brain.
Since ADBE is only triggered during high brain activity, drugs designed to target this process could have fewer side effects.
The researchers, however, warned that since ABDE is also implicated in a range of brain functions, more research is needed to establish what the effects of manipulating this molecule might be on these processes.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
