Has science unearthed the Holy Grail of pain relief?

12.07.2007
Scientists studying one of nature’s simplest organisms have helped to unravel the structure of a key molecule that controls pain in humans.

The findings – published in the top scientific journal Nature – could rapidly advance research into the next generation of painkillers for relief of chronic conditions such as migraine and backache.

Chronic pain, unlike the acute pain associated with trauma, has no apparent physiological benefit, often being referred to as the ‘disease of pain’.

Complete and lasting relief of chronic pain is rare and often the clinical goal is pain management through one or more medications.

But now researchers at The University of Manchester have examined microscopic amoeboid organisms commonly called slime moulds in a bid to gain greater insight into these pain molecules, known as ‘P2X receptors’.

“In humans, P2X receptors look identical to one another and so scientists have had difficulty understanding how they function,” said Dr Chris Thompson, who carried out the research with Professor Alan North and Dr Sam Fountain in the Faculty of Life Sciences.

“By looking at slime mould we were effectively able to turn the evolutionary clock back a billion years to see how a more primitive P2X molecule functions.”

The team discovered that there was only a 10% similarity between human P2X and the slime mould equivalent. They were therefore able to deduce from evolutionary theory that it was these similar parts of the molecule that probably regulate pain in humans.

“It’s a big step forward in understanding how the molecule works and should make it possible to develop drugs that block the receptors’ actions,” said Dr Thompson.

“Inhibiting P2X as a potential pain-relief therapy would be the Holy Grail of rational drug design and could revolutionise the way we manage chronic pain conditions like back pain and migraine.”

The research, published in Nature tomorrow (Thursday, July 12), was funded by the Wellcome Trust, the Medical Research Council and the Lister Institute for Preventive Medicine.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
