Scripps research scientists describe how T-cell receptors and coreceptors interact during an immune response
A group of scientists at The Scripps Research Institute has solved a mystery that has dogged immunologists for many years: how T-cell receptors interact with their coreceptor proteins at the beginning of an immune response.
T-cell receptors and coreceptor molecules are both large proteins displayed on the surface of T cells, and they play an essential role during t
Some parasites trigger their own destruction by altering their hosts’ behavior, researchers at The University of Arizona and Wesleyan University report in Nature.
Many parasites have developed mechanisms that suppress their hosts’ ability to fight them off or even change their behavior in favor of the parasite. “We found the opposite is true with tiger moth caterpillars and their parasites,” said UA Regents’ Professor Emerita Elizabeth Bernays.

Inhaling CO prevents transplant rejection in mice, say U-M scientists. Could become part of future treatment regimen for organ transplant patients
Could become part of future treatment regimen for organ transplant patients. Carbon monoxide, a poisonous gas that kills thousands of Americans every year, could turn out to be a life-saver for patients recovering from organ transplants, strokes or heart attacks, according to new research from the University of Michigan Cardiovascular
When a pharmaceutical company puts drug samples into the hands of residents as a form of marketing, how does it influence their prescribing behavior? To what extent are treatment decisions based on which samples are available and further, what are the implications for patient care as well as resident education? While this is a frequently debated issue, there has been little objective data describing how drug samples affect resident physicians. In a study published in the August issue of The America
New study finds improvement of fibromyalgia symptoms with few side effects
The mechanism of fibromyalgia, a chronic illness characterized by muscle pain, fatigue, and sleep disturbances, is unknown and medications used to treat it (such as antidepressants, antiepileptics, muscle relaxants, antiinflammatories, sedative hypnotics, pain relievers and nutriceuticals) have had limited success. New research findings indicate that the pain associated with this disease may be due to abno
Study examines occurrence of knee pain with pain at other joints and its effect on physical function and mental health
Joint pain, especially in the knees, is a common complaint in older patients and can impact quality of life. A team of researchers recently set out to examine how often knee pain is accompanied by pain elsewhere in the body and whether the presence of multiple joint pain affects older patients’ general health and psychological status. Their findings, publ
The catalytic reforming of liquid fuels offers an attractive solution to supplying hydrogen to fuel cells while avoiding the safety and storage issues related to gaseous hydrogen. Existing catalytic support structures, however, tend to break down at the high temperatures needed to prevent fouling of the catalytic surface by soot.
Now, researchers at the University of Illinois at Urbana-Champaign have developed porous support materials that can withstand the rigors of high-temp
NASA’s Chandra X-ray Observatory survey of nearby sun-like stars suggests there is nearly three times more neon in the sun and local universe than previously believed. If true, this would solve a critical problem with understanding how the sun works.
“We use the sun to test how well we understand stars and, to some extent, the rest of the universe,” said Jeremy Drake of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. “But in order to understand the sun,
Working with mice, University of Iowa scientists and colleagues from Okayama University, Japan, have shown that it is possible to cure a certain type of hereditary deafness by silencing a gene that causes hearing loss.
Richard Smith, M.D., the Sterba Hearing Research Professor in Otolaryngology at the UI Roy J. and Lucille A. Carver College of Medicine, described the study as a proof-of-principle experiment, but added that the success may point the way to new treatments for deafnes
Circulating stem cells play a minor role in repairing lung damage, according to a team of scientists who used male and female chromosomal differences to analyze the repair process in lung transplant patients.
Reporting in today’s edition of the journal Transplantation, lead author Dani Zander, M.D., of The University of Texas Medical School at Houston, and colleagues at the University of Florida College of Medicine found that less than 1 percent of a certain type of reparative
Patients who are delirious during hospitalization one year later had 13 percent fewer days of survival during the following year when compared to patients without delirium, according to a study published this month in the Archives of Internal Medicine.
Delirium is a frequent problem for hospitalized older patients with consequences ranging from increased morbidity and mortality, persistent functional decline and increased and costlier hospital stay to higher rates of nursing ho
Study focuses on hepatoma
Primary liver cancer is much more likely to take root when a naturally occurring enzyme is in short supply, a team of researchers has found at Mount Sinai Hospital’s Samuel Lunenfeld Research Institute.
Using a knockout mouse model, the team has found that the likelihood of hepatoma, or primary liver cancer, increases substantially when half the normal amount of an enzyme called Plk4 is present. Furthermore, 60 per cent of patients with h
Astrobiologists, who search for evidence of life on other planets, may find a proposed Neutron/Gamma ray Geologic Tomography (NUGGET) instrument to be one of the most useful tools in their toolbelt.
As conceived by scientists at the Goddard Space Flight Center (GSFC) in Greenbelt, Md., NUGGET would be able to generate three-dimensional images of fossils embedded in an outcrop of rock or beneath the soil of Mars or another planet. Tomography uses radiation or sound waves to look i
