Researchers from Queen Mary, University of London and the University of Surrey have found a protein inside blood vessels with an ability to protect the body from substances which cause cardiovascular disease.
The findings, published online in the journal Cardiovascular Research, have revealed the protein protein pregnane X receptor (PXR) can switch on different protective pathways in the blood vessels.
Co-author Dr David Bishop-Bailey, based at Queen Mary's William Harvey Research Institute, said they found the protein was able to sense a wide variety of drugs, foreign chemicals and food products in the blood and switch on specific pathways to deal with them.
"We've known for a long time that this protein has an important role sorting out waste products in the liver - now we believe it could have an important role in protecting the body against cardiovascular disease," he said.
Dr Karen Swales, based at the University of Surrey, said: "Heart and circulatory disease is the UK's biggest killer. Discovering that the protein pregnane X receptor (PXR) could protect blood vessels has major implications for the prevention of cardiovascular disease."
"We knew if PXR played similar protective roles in blood vessels to those in the liver, it could protect the vessels from damage caused by harmful substances in the blood."
The researchers used human tissue and blood vessel cells in culture and found PXR was present and active.
Dr Bishop-Bailey added: "We introduced specific PXR activating drugs and saw a co-ordinated increase in metabolising and anti-oxidant enzyme pathways.
"Since blood travels everywhere in the body, PXR has the potential to provide protection not just through its actions in the liver, but anywhere in the entire body. If we can work out how to manipulate PXR to turn on detoxification and antioxidant pathways in blood vessels, we may be a step closer to preventing our nation's biggest killer."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
