Researchers have zoomed in on what is going on at the molecular level when the body recognizes and defends against an attack of pathogens, and the findings, they say, could influence how drugs are developed to treat autoimmune diseases.
A cancer-research team has identified a protein that may be a major culprit when breast cancer metastasizes to the brain. The cancer’s spread to the brain is often undetected until patients start to develop symptoms such as seizures, headaches, and trouble thinking.
Scientists have, for the first time, generated induced pluripotent stem (iPS) cells lines from non-cryoprotected brain tissue of patients with Alzheimer's disease.
Yale researchers have identified the mechanism behind a molecular variation that reduces risk of stroke in children with sickle cell anemia.
New research has revealed two new genetic causes of neonatal diabetes. The study provides further insights on how the insulin-producing beta cells are formed in the pancreas.
By attaching a cancer-killer protein to white blood cells, biomedical engineers have demonstrated the annihilation of metastasizing cancer cells traveling throughout the bloodstream.
Your nose is not the only organ in your body that can sense cigarette smoke wafting through the air. Scientists have shown that your lungs have odor receptors as well.
Researchers have found that dysfunction in a single gene in mice causes fasting hyperglycemia, one of the major symptoms of type 2 diabetes.
New research results suggest a link between the increasing number of people who have developed allergic asthma in the West and a lack of fruits and vegetables in Western diets.
Researchers have completed a comprehensive genomic analysis of cervical cancer in two patient populations. The study identified recurrent genetic mutations not previously found in cervical cancer, including at least one for which targeted treatments have been approved for other forms of cancer.
Doctors may need to treat high blood pressure in women earlier and more aggressively than they do in men, according to scientists.
Cancer investigators have genetically engineered a new mouse that mimics a common form of leukemia in humans. Studying the model could lead to new understanding of the disease, they say.
Having shingles, a viral infection that causes a painful rash, may increase the risk of having a stroke years later, according to new research.
Psychologists say, yes, brain training works, but "there's a catch." Training for a particular task does heighten performance, but that advantage doesn't necessarily carry over to a new challenge.
New research has shown that cells demonstrate remarkable flexibility and versatility when it comes to how they divide– a finding with potential links to the underlying causes of many cancers.
High levels of “good” cholesterol and low levels of “bad” cholesterol are correlated with lower levels of the amyloid plaque deposition in the brain that is a hallmark of Alzheimer’s disease, researchers have found.
A new technique for studying the structure of the RSV virion and the activity of RSV in living cells could help researchers unlock the secrets of the virus, including how it enters cells.
Although a population of bacteria may be genetically identical, individual bacteria within that population can act in radically different ways. Researchers showed that when a bacterial cell divides into two daughter cells there can be an uneven distribution of cellular organelles. The resulting cells can behave differently from each other, depending on which parts they received in the split.
New findings suggest the oxytocin receptor, a gene known to influence mother-infant bonding and pair bonding in monogamous species, also plays a special role in the ability to remember faces. This research has important implications for disorders in which social information processing is disrupted, including autism spectrum disorder.
The mechanism by which some bacteria are able to survive antibacterial treatment has been revealed for the first time by Hebrew University of Jerusalem researchers. Their work could pave the way for new ways to control such bacteria. Learn more...
A safe and effective malaria vaccine is high on the wish list of most people concerned with global health. Results published this week in PLOS Pathogens suggest how a leading vaccine candidate could be vastly improved.
Researchers at Oregon Health & Science University have discovered that an antioxidant designed by scientists more than a dozen years ago to fight damage within human cells significantly helps symptoms in mice that have a multiple sclerosis-like disease.
In the study, published online in Cell Reports, scientists found that inhibiting the action of a protein called BRD4 caused cancer cells to die in a mouse model of malignant peripheral nerve sheath tumors (MPNSTs). Learn more...
University at Buffalo research published today in Infection and Immunity shows that Streptococcus pneumoniae and Streptococcus pyogenes do persist on surfaces for far longer than has been appreciated. The findings suggest that additional precautions may be necessary to prevent infections, especially in settings such as schools, daycare centers and hospitals.
Sanford-Burnham Medical Research Institute scientists have discovered a new molecule that forms when certain white blood cells—macrophages—are stimulated in response to pathogens. The molecule, termed "THRIL," helps regulate the immune response and shows an association with Kawasaki disease.
