External cues affect cell's ability to migrate

In a paper published today in the journal, Cell, a team from the University of North Carolina at Chapel Hill has explained for the first time how a long-studied protein complex affects cell migration and how external cues affect cell's ability to migrate.

Combination of implanted DCs and EBRT effective in creating sarcoma tumor immune response

A team of 18 researchers at Moffitt Cancer Center in Tampa, Fla., have found that treating high-risk, soft tissue sarcoma patients with a combination of implanted dendritic cells (immune system cells) and fractionated external beam radiation (EBRT) provided more than 50 percent of their trial patients with tumor-specific immune responses lasting from 11 to 42 weeks.

Scientists determine chemical features of DHPS enzyme's active site

More than 70 years after the first sulfa drugs helped to revolutionize medical care and save millions of lives, St. Jude Children's Research Hospital scientists have determined at an atomic level the mechanism these medications use to kill bacteria. The discovery provides the basis for a new generation of antibiotics that would likely be harder for bacteria to resist and cause fewer side effects.

Poor sleep alters immune system response to stress in older adults

Older adults who sleep poorly have an altered immune system response to stress that may increase risk for mental and physical health problems, according to a study led by a University of Rochester Medical Center researcher.

Researchers confirm how food poisoning bacteria hijack cell's sense of direction

Working in the emerging field of systems biology, UT Southwestern Medical Center researchers mathematically predicted how bacteria that cause food poisoning hijack a cell's sense of direction and then confirmed those predictions in living cells.

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.

Ten symptoms and signs that a child may need a doctor

Unfortunately, kids get sick. Fighting a virus or common cold is good for a child's immune system and can help build antibodies that protect them from dangerous illnesses. Still, there are times when that tummy ache or cough may require medical attention.

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.

Treatment with vitamin D reduces size of uterine fibroids

Treatment with vitamin D reduced the size of uterine fibroids in laboratory rats predisposed to developing the benign tumors, reported researchers funded by the National Institutes of Health.

CSL Behring to receive 2012 EURORDIS Award for pioneering work

CSL Behring is the recipient of a 2012 EURORDIS Award for its pioneering work in developing and manufacturing therapies used to treat rare and serious medical conditions.

Cyclotides discovery may open up new possibilities for immune suppression

A team of researchers at the MedUni Vienna, together with scientists from the University Hospital of Freiburg, has decoded a mechanism in cyclic plant peptides, known as cyclotides, from the family of coffee plants (Rubiaceae) that could open up new possibilities for immune suppression.

Parasitic worms could offer new treatment hope for MS patients

Parasitic worms could offer a new treatment hope for patients suffering from the autoimmune disease multiple sclerosis, scientists believe.

CD4 T cells can directly kill HIV-infected cells

A subpopulation of the immune cells targeted by HIV may play an important role in controlling viral loads after initial infection, potentially helping to determine how quickly infection will progress. In the February 29 issue of Science Translational Medicine, a team of researchers from the Ragon Institute of Massachusetts General Hospital (MGH), MIT and Harvard describe finding a population of HIV-specific CD4 T cells - cells traditionally thought to direct and support activities of other immune cells - that can directly kill HIV-infected cells.

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.

Gluten-free, casein-free diet more effective in improving ASD behaviors and symptoms

A gluten-free, casein-free diet may lead to improvements in behavior and physiological symptoms in some children diagnosed with an autism spectrum disorder (ASD), according to researchers at Penn State. The research is the first to use survey data from parents to document the effectiveness of a gluten-free, casein-free diet on children with ASD.

New portable device can quickly diagnose infectious disease

Infectious diseases can spread very rapidly, so quickly identifying them can be crucial to stopping an epidemic. However, current testing for such diseases can take hours and days. But not for much longer.

New prebiotic formula helps colonize newborn's gut with beneficial bacteria

Adding prebiotic ingredients to infant formula helps colonize the newborn's gut with a stable population of beneficial bacteria, and probiotics enhance immunity in formula-fed infants, two University of Illinois studies report.

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.

New research shows beneficial side effect of anti-allergy parasite

New research is showing a beneficial side effect of parasites for our health. Hygiene Hypothesis: As rates of allergy are reported to have tripled in the UK in the past decade, the scientific finger is pointing to an over-sanitised lifestyle making our immune responses overactive. Now, a team of biologists at the University of Edinburgh, led by Professor Rick Maizels, are investigating how parasitic worms could offer a cure for modern illnesses.

First clinical assessment of how interferon fights infections in people

A drug once taken by people with HIV/AIDS but long ago shelved after newer, modern antiretroviral therapies became available has now shed light on how the human body uses its natural immunity to fight the virus—work that could help uncover new targets for drugs.
