Addition of inflammatory biomarkers to clinical variables improve mortality prediction in COPD

The addition of changes in inflammatory biomarkers to established clinical variables improves the prediction of mortality in patients with chronic obstructive pulmonary disease (COPD), according to a new study.

CUMC scientists develop a way to recreate personalized immune mouse

Columbia University Medical Center (CUMC) scientists have developed a way to recreate an individual's immune system in a mouse. The "personalized immune mouse" offers researchers an unprecedented tool for individualized analysis of abnormalities that contribute to type 1 diabetes and other autoimmune diseases, starting at the onset of disease.

Study addresses how human body controls gamma-herpesviruses

New research from the Trudeau Institute addresses how the human body controls gamma-herpesviruses, a class of viruses thought to cause a variety of cancers. The study, carried out in the laboratory of Dr. Marcia Blackman, awaits publication in The Journal of Immunology.

New inexpensive medical sensor may simplify diagnosis of diseases

An inexpensive new medical sensor has the potential to simplify the diagnosis of diseases ranging from life-threatening immune deficiencies to the common cold, according to its inventors at the Stanford University School of Medicine.

A novel approach to treating rheumatoid arthritis

Rheumatoid arthritis is a crippling disease and is caused when the body's own immune system attacks the joints and leads to chronic pain and inflammation. A team from Newcastle University funded by Arthritis Research UK have discovered an approach which could effectively prevents white blood cells from reaching the joints and causing more damage.

Europe conference to discuss on new HIV indicator diseases

Today, heterosexuals in Europe are at particular risk of carrying HIV for so long that they remain undiagnosed until their immune system starts to fail and they become ill. An international study under the leadership of the HIV in Europe initiative has now revealed that a number of diseases, including herpes zoster and certain forms of cancer, should be on the list of indicators for having HIV - and thus serve to prompt health care professionals to suggest an HIV-test to their patients.

First study to focus on platelet genetics in African Americans

Researchers, led by scientists from Johns Hopkins, have found five previously unknown gene mutations believed to be associated with elevated blood platelet counts in African-Americans, findings they say could someday lead to the development of new drugs to help prevent coronary artery disease.

New HS44 molecule inhibits lung metastasis

One type of white blood cell, the Natural Killer T Cells, fights against infections and tumours by freeing cytokine proteins which activate the body's immune response and destroy infected or malignant cells. To do so they must receive an activation signal. Specific receptors located on their surface act as switches: they activate the lymphocyte in presence of an antigen, a molecule which triggers alarm signals.

Loss of STAT1 transcription factor causes breast cancer development

Breast cancer represents about a fifth of all cancers diagnosed in women. The reasons for the rapid progression of the disease remain relatively poorly understood but recent work in the group of Veronika Sexl at the University of Veterinary Medicine, Vienna has pointed the finger strongly at loss or inactivation of the transcription factor STAT1.

NKT cells may reduce monocytes accumulation, prevent lung injury in severe flu

While some scientists report engineering a super virulent strain of the H5N1 influenza virus, which could potentially wipe out a significant percentage of the human population, another group of researchers from the United Kingdom now reports a discovery that may one day help mitigate the deadly effects of all flu strains.

Study identifies new processes that lead to development of novel cell implicated in allergies

A collaboration between scientists in Trinity College Dublin and the United Kingdom has identified new processes that lead to the development of a novel cell implicated in allergies. The discovery has the potential for new strategies to treat asthma and other allergic diseases.

Study evaluates how environmental triggers might alter epigenetics of CFS

A University of Toronto Scarborough (UTSC) researcher is examining how environmental triggers might alter gene function in people with Chronic Fatigue Syndrome. The research could lead to better insights into the disease and eventually to new treatments.

Nicotine can contribute to atherosclerosis

Cigarette smoke has long been considered the main risk factor for heart disease. But new research from Brown University in Providence, R.I., shows that nicotine itself, a component of cigarette smoke, can contribute to the disease process by changing cell structure in a way that promotes migration and invasion of the smooth muscle cells that line blood vessels.

Scientists identify specific mechanisms by which vitamin D inhibits inflammation

Researchers at National Jewish Health have discovered specific molecular and signaling events by which vitamin D inhibits inflammation. In their experiments, they showed that low levels of Vitamin D, comparable to levels found in millions of people, failed to inhibit the inflammatory cascade, while levels considered adequate did inhibit inflammatory signaling.

Elevated levels of two TLRs can trigger heart disease and diabetes

UC Davis scientists have uncovered a key suspect in the destructive inflammation that underlies heart disease and diabetes. The new research shows elevated levels of a receptor present on leucocytes of the innate immune response in people at risk for these chronic diseases.

New microfluidic device can rapidly isolate target cells

Separating complex mixtures of cells, such as those found in a blood sample, can offer valuable information for diagnosing and treating disease. However, it may be necessary to search through billions of other cells to collect rare cells such as tumor cells, stem cells or fetal cells. "You're basically looking for a needle in a haystack," says Sukant Mittal, a graduate student in the Harvard-MIT Division of Health Sciences and Technology.

Targeting patient's own dendritic cells may help restore the immune system

Aggressive ovarian tumors begin as malignant cells kept in check by the immune system until, suddenly and unpredictably, they explode into metastatic cancer. New findings from scientists at The Wistar Institute demonstrate that ovarian tumors don't necessarily break "free" of the immune system, rather dendritic cells of the immune system seem to actively support the tumor's escape.

Scientists discover the off signal for inflammation

Proteins, the building block for all living organisms, are the ultimate transformers - able to splice and switch roles and functions within the human body. But when these changes go wrong, diseases such as cancers and arthritis may result, says University of British Columbia researcher Chris Overall.

Study: 3D organization of chromosomes plays a role in cancer genomics

It is well understood that chromosomal translocation - a process whereby pieces of two chromosomes break off and exchange places - is a hallmark of many cancers including leukemia, thyroid cancer and lymphoma and play an important part in how healthy cells become cancerous. The role spatial proximity plays in why certain chromosomal translocations happen repeatedly, however, has been a long-standing area of debate among scientists.
