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: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
