People suffering from IBD can experience an array of symptoms ranging from mild discomfort to debilitating disease requiring surgical removal of large parts of the intestine. Current therapeutic options in IBD are very limited and surgery is often the only option.
In the new discovery published in the scientific journal Gastroenterology, the Irish scientists have demonstrated that they can almost completely reverse the symptoms of IBD in a disease model using a new class of drugs known as hydroxylase inhibitors.
“Under normal conditions our gastro-intestinal tract is lined with cells that block the contents of the gut from leaking into the intestine,” explains Professor Cormac Taylor from the UCD Conway Institute, University College Dublin, one of the principal scientists involved in the discovery. “However, when a person is suffering from IBD this barrier is broken and the contents of the gut leak out into surrounding areas.”
“When we applied the new drugs, the gut was tricked into thinking that it was being deprived of oxygen and this activated protective pathways which in turn prevented the death of the cells that line the gastrointestinal tract,” continues Professor Taylor.
While completing their investigation, the Irish researchers became aware of a similar study taking place at the University of Colorado, Denver. This study appears as an accompanying article in the same issue of Gastroenterology. The US study, while using a different hydroxylase inhibitor, supports the Irish scientist’s research findings.
The Irish and US research groups will now begin a collaborative investigation to bring the discovery to the next stage which involves developing a new therapeutic which can be delivered safely to humans.
“By working in collaboration with Sigmoid Biotechnologies, a Dublin based drug delivery company, we intend to focus on developing methods to safely deliver these drugs to their intended target in the inflamed gut,” says Professor Taylor.
“These findings show that cross-university partnerships adopted by the new generation of Science Foundation Ireland funded Irish scientists will help to drive Ireland’s future knowledge economy,” says Professor Padraic Fallon, SFI Stokes Professor, TCD School of Medicine, Trinity College Dublin, the other principal research scientist involved in the Irish discovery.
“If Ireland is to compete at the forefront of scientific discoveries and to develop partnerships with the international biotechnology sector, our scientist must work together in synergy,” continues Professor Fallon.
The Irish research groups led by Professor Taylor at University College Dublin and Dr Fallon at Trinity College Dublin have recently received independent investigator awards from Science Foundation Ireland totalling over €1 million each.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
