New drug target found for cystic fibrosis lung disease

08.11.2012
Discovery could lead to new treatment for lung inflammation

Vancouver researchers have discovered the cellular pathway that causes lung-damaging inflammation in cystic fibrosis (CF), and that reducing the pathway’s activity also decreases inflammation. The finding offers a potential new drug target for treating CF lung disease, which is a major cause of illness and death for people with CF.

“Developing new drugs that target lung inflammation would be a big step forward,” says Dr. Stuart Turvey, who led the research. Dr. Turvey is the director of clinical research and senior clinician scientist at the Child & Family Research Institute and a pediatric immunologist at BC Children’s Hospital. He is an associate professor in the Department of Pediatrics at the University of British Columbia.

The research was published online last week in the Journal of Immunology.

For the study, researchers compared the immune response of normal lung cells with that of CF lung cells after exposing both types of cells to bacteria in the lab. In healthy cells, exposure to bacteria triggers the cell to secrete special molecules that attract immune cells to fight the infection.

In CF lung cells, the researchers discovered that a series of molecular events called the unfolded protein response is more highly activated. It causes the CF lung cells to secrete more molecules that attract an excessive amount of immune cells, which leads to increased inflammation.

They also found that treating the CF cells with a special chemical normalized the unfolded protein response and stabilized the cells’ immune response.

CF is the most common genetic disease affecting young Canadians. One in every 3600 children born in Canada has CF. There is no cure. A build-up of mucus in the lungs causes people with CF to be susceptible to bacterial lung infections, which trigger inflammation and swelling. Over time, the recurring cycle of infections and inflammation damages the lungs and can lead to the need for lung transplantation. The only treatments for lung inflammation are steroids and anti-inflammatory medications, which can have significant side effects.

The researchers are planning further study to validate these findings in a larger number of lung cell samples from people with CF.

This discovery resulted from a collaboration among Vancouver investigators and trainees based at the Child & Family Research Institute at BC Children’s Hospital, the University of British Columbia, and the Providence Heart + Lung Institute at St. Paul’s Hospital.

This research was funded by Cystic Fibrosis Canada and the Michael Smith Foundation for Health Research.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
