(Press-News.org) Rheumatoid arthritis (RA) is an autoimmune disorder in which immune cells attack the joints, causing inflammation, swelling, and erosion. Specific sets of immune cells, known as T cells, are responsible for inducing disease. In this issue of the Journal of Clinical Investigation, researchers led by Harvey Cantor at Harvard University analyzed the contributions of different subsets of T cells to an RA-like condition in mice. Cantor and colleagues identified a subset of regulatory T cells (CD8+ Tregs) that can remove pathogenic T cell subsets and inhibit disease progression. Additionally, they identified small proteins that induced more CD8+ Tregs. These findings suggest that enhancing specific T cell subsets may be useful in combating RA and other autoimmune diseases.

Rooting out recurrent breast cancer
Due to chemotherapy resistance and a high rate of relapse, triple negative cancers are among the most difficult breast cancers to treat. In this issue of the Journal of Clinical Investigation, researchers led by Carlos Arteaga at Vanderbilt University identified a protein, TGF-β, that is highly expressed in triple negative breast cancer cells after chemotherapy. In a mouse model of breast cancer, TGF-β both diverted cells down a path to becoming cancerous and allowed for cancer to come back after treatment. Importantly, loss ...
Comparing mechanical clot removal and standard medical therapy for severe stroke
2013-02-08
WASHINGTON – Results of the first randomized controlled study to evaluate a procedure that removes blood clots in the brain from patients experiencing severe strokes will be presented at the International Stroke Conference in Honolulu, Hawaii on Feb. 8. The study also evaluates if imaging techniques were helpful in identifying patients who potentially would benefit most from clot removal.
In addition to the presentation, the full study, led by Chelsea Kidwell, M.D., professor of neurology and director of the Stroke Center at Georgetown University Medical Center, will ...
Yeast we can! New report answers questions on microbiology and beer
2013-02-08
WASHINGTON, DC – February 5, 2013 – What do microbes have to do with beer? Everything! Because the master ingredient in beer is yeast – a microbe – and every step in the brewing process helps the yeast do its job better. A new freely-available report; FAQ: If the Yeast Ain't Happy, Ain't Nobody Happy: The Microbiology of Beer explores the synergy between microbiology and brewing beer.
"Every time someone brews a batch of beer, in a very real sense he or she is doing a microbiology experiment. If you brew beer at home, you're a microbiologist.' says Dr. Charles Bamforth ...

Combining plasma screening methods better identifies diagnostic and therapeutic targets
2013-02-08
BETHESDA, MD — February 8, 2013 — For the first time, scientists have combined genomic and proteomic analysis of blood plasma to enhance identification of genetically regulated protein traits. This could be applied to any large association study of civilization diseases where blood plasma has been collected, vastly improving a clinician's ability to identify disease susceptibility in individuals and populations. This advance is published in the February 2013 issue of the journal Genetics.
"We hope that combining genome-wide with proteome-wide screening of blood plasma ...
Putting our heads together: Canines may hold clues to human skull development

BETHESDA, MD – February 8, 2013 -- Man's best friend may touch our hearts with their empathy, companionship, playfulness and loyalty, and they may also lead us to a deeper understanding of our heads.
In the article, "The Genetics of Canine Skull Shape Variation," in the February issue of the Genetics Society of America's journal, Genetics, Jeffrey J. Schoenebeck, PhD, and Elaine A. Ostrander, PhD, researchers at the National Human Genome Research Institute (NHGRI), the National Institutes of Health (NIH), review progress in defining the genes and pathways that determine ...
Physicians' belief about obesity causes impacts advice and care
2013-02-08
How physicians view the causes of obesity may impact the advice they give their patients. The findings are from a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health who compared the relationship between primary care physicians' beliefs about the causes of obesity with the frequency of nutritional counseling. They found that physicians who believed over consumption of food to be a major contributor to obesity were significantly more likely to counsel their patients to modify nutritional habits. The results are featured in the February 2013 ...
New strategy prevents rheumatoid arthritis in mice
2013-02-08
BOSTON—Dana-Farber Cancer Institute scientists have demonstrated a new strategy for treating autoimmune disease that successfully blocked the development of rheumatoid arthritis in a mouse model. They say it holds promise for improved treatment of arthritis and other autoimmune disorders in people.
The scientists report in the Journal of Clinical Investigation that infusing a highly specific type of cell that regulates immune responses into arthritis-prone mice shut down the cascade of inflammation that damages tissues and joints.
The method worked best when the infusions ...
New brain-test app
2013-02-08
Two years ago, researcher Josef Bless was listening to music on his phone when he suddenly had an idea.
"I noticed that the sounds of the different instruments were distributed differently between the ears, and it struck me that this was very similar to the tests we routinely use in our laboratory to measure brain function. In dichotic listening, each ear is presented with a different syllable at the same time (one to the left and one to the right ear) and the listener has to say which syllable seems clearest. The test indicates which side of the brain is most active during ...
Implants make light work of fixing broken bones
2013-02-08
Artificial bone, created using stem cells and a new lightweight plastic, could soon be used to heal shattered limbs.
The use of bone stem cells combined with a degradable rigid material that inserts into broken bones and encourages real bone to re-grow has been developed at the Universities of Edinburgh and Southampton.
Researchers have developed the material with a honeycomb scaffold structure that allows blood to flow through it, enabling stem cells from the patient's bone marrow to attach to the material and grow new bone. Over time, the plastic slowly degrades as ...
