Key to immune system disease could lie inside the cheek
Powerful immunosupressant cells obtained from cheek tissue
2012-03-22
(Press-News.org) Powerful new cells created by Cardiff University scientists from cheek lining tissue could offer the answer to disorders of the immune system.
While the body's immune system protects against many diseases, it can also be harmful. Using white blood cells (lymphocytes), the system can attack insulin-producing cells, causing diabetes, or cause the body to reject transplanted organs.
A team from Cardiff's School of Dentistry led by Professor Phil Stephens, with colleagues from Stockholm's Karolinska Institute, have found a new group of cells with a powerful ability to suppress the immune system's action.
The team took oral lining cells from the insides of patients' cheeks and cloned them. Laboratory tests showed that even small doses of the cells could completely inhibit the lymphocytes.
The breakthrough suggests that the cheek cells have wide-ranging potential for future therapies for immune system-related diseases. Existing immune system research has focussed on adult stem cells, particularly those derived from bone marrow. The cheek tissue cells are much stronger in their action.
Dr Lindsay Davies, a member of the Cardiff team, said: "At this stage, these are only laboratory results. We have yet to recreate the effect outside the laboratory and any treatments will be many years away. However, these cells are extremely powerful and offer promise for combating a number of diseases. They are also easy to collect – bone marrow stem cells require an invasive biopsy, whereas we just harvest a small biopsy from inside the mouth."
The findings have just been published online in Stem Cells and Development. The team has now been funded by the Medical Research Council to investigate the cloned cells further.

A group of biologists from Denmark and the US led by Jakob Christensen-Dalsgaard, University of Southern Denmark, and Catherine Carr, University of Maryland, have shown that the turtle ear is specialized for underwater hearing. The new discovery is published in Proceedings of the Royal Society B March 21st , Special features of the turtle ear – a large, air-filled middle ear and a movable tympanic disk increase its sensitivity for underwater sound. Laser measurements of disk vibrations in response to underwater sound show up to 100-fold larger vibrations of the disk than ...

The behaviour of some of the most elusive particles in the known universe can be simulated using three atoms in a lab, researchers at the Centre for Quantum Technologies (CQT) at the National University of Singapore have found.
Principal Investigator Dimitris G. Angelakis and his group members Changsuk Noh and Blas Rodriguez-Lara have devised a scheme that uses the quantum states of three charged ions to simulate the 'oscillations' of neutrinos. The proposal is published in the March issue of New Journal of Physics.
Neutrinos are pesky things to study: they barely interact ...

A recent study conducted at Marshall University may eventually help scientists develop new treatments for prostate cancer, the most common malignancy in American men.
The study, which focused on the effects of cadmium on the prostate, was conducted by Dr. Pier Paolo Claudio, an associate professor in the Biomedical Sciences Graduate Program and Department of Biochemistry and Microbiology at the university's Joan C. Edwards School of Medicine, and an international team of colleagues from the University of L'Aquila and the National Cancer Institute in Italy, and the University ...

A new study suggests that climate change could pose a risk for Antarctic fur seals in their first few months of life.
The study, published in the journal Physiological and Biochemical Zoology, found that changing weather conditions can impact the metabolic rates of fur seal pups. Climate models predict windier and wetter conditions in Antarctica in the coming years, and that could cause young seals to assign more energy to thermoregulation, leaving less available for growth and development.
For their study, a team of scientists led by Dr. Birgitte McDonald (University ...
