Wistar scientists find key to keeping killer T cells in prime shape for fighting infection, cancer
Like tuning a violin to produce strong, elegant notes, researchers at The Wistar Institute have found multiple receptors on the outside of the body's killer immune system cells which they believe can be selectively targeted to keep the cells in superb infection- and disease-fighting condition.   view more (2008-12-01)

Study unmasks how ovarian tumors evade immune system
Scientists at Johns Hopkins have determined how the characteristic shedding of fatty substances, or lipids, by ovarian tumors allows the cancer to evade the body's immune system, leaving the disease to spread unchecked   view more (2008-12-01)

Researchers identify how binge drinking may drive heart disease
As the holidays arrive, a group of researchers has identified the precise mechanisms by which binge drinking contributes to clogs in arteries that lead to heart attack and stroke, according to a study published today in the journal Atherosclerosis.   view more (2008-11-26)

Researchers discover strategy for predicting the immunity of vaccines
In the first study of its kind, researchers at the Yerkes National Primate Research Center and Emory Vaccine Center, Emory University, have developed a multidisciplinary approach involving immunology, genomics and bioinformatics to predict the immunity of a vaccine without exposing individuals to... view more (2008-11-24)

UT Southwestern researchers develop new strategy for broad spectrum anti-viral drugs
Bavituximab, an anti-viral drug developed by UT Southwestern Medical Center researchers, shows promise as a new strategy to fight viral diseases, including potential bioterrorism agents.   view more (2008-11-24)

Researcher tricks immune system in diabetic mice
The body's immune system hates strangers. When its security patrol spots a foreign cell, it annihilates it.   view more (2008-11-21)

Landmark study defines benefits of early HIV testing and treatment for infected infants
Testing very young babies for HIV and giving antiretroviral therapy (ART) immediately to those found infected with the virus dramatically prevents illness and death, according to a report in the New England Journal of Medicine.   view more (2008-11-20)

JDRF funded research shows promise for prevention, reversal of type 1 diabetes
Researchers at the University of California, San Francisco have reported that two common cancer drugs have been used to block and reverse type 1 diabetes in mice.   view more (2008-11-19)

2 new compounds show promise for eliminating breast cancer tumors
Two new compounds created by a University of Central Florida professor show early promise for destroying breast cancer tumors.   view more (2008-11-19)

Results of landmark study of HIV vaccine published in the Lancet
Results from the Step study, a test-of-concept efficacy study of a Merck & Co., Inc. HIV vaccine candidate, were published online today in two papers in The Lancet. These analyses of the Step study are being conducted, presented and published to inform the continued search for an effective HIV... view more (2008-11-13)

Researchers aim to over-stress already taxed mantle cell lymphoma cells
Cancer cells are already stressed by the fast pace they require to grow and spread and scientists believe a little more stress just may kill them.   view more (2008-11-11)

Battling bacteria in the blood: Researchers tackle deadly infections
It's a leading cause of death, but no one knows for sure how and why it happens. It's a major source of health care costs, adding days or weeks to the hospital stays and lost work time of millions of people. But no one fully understands how best to fight it.   view more (2008-11-11)

Researchers use chemical from medicinal plants to fight HIV
Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, the cell changes in many ways, and its disease fighting ability is compromised.   view more (2008-11-10)

Engineered killer T cell recognizes HIV-1's lethal molecular disguises
Researchers at the University of Pennsylvania School of Medicine and colleagues in the United Kingdom have engineered T cells able to recognize HIV-1 strains that have evaded the immune system.   view more (2008-11-10)

T cell-based HIV vaccine candidate demonstrates positive results
The question of whether or not to continue to pursue the development of T-cell-based HIV-1 vaccines has been a source of controversy following last year's widely publicized failure of the field's most promising candidate, a vaccine developed by Merck known as V520.   view more (2008-11-10)

Protein identified that turns off HIV-fighting T cells
In HIV-infected patients the body's immune system is unable to fight off the virus. A new study to be published online on November 10th in the Journal of Experimental Medicine shows that T cells in HIV-infected individuals express a protein called TIM-3, which inactivates their virus killing... view more (2008-11-10)

Protein 'tubules' free avian flu virus from immune recognition
A protein found in the virulent avian influenza virus strain called H5N1 forms tiny tubules in which it "hides" the pieces of double-stranded RNA formed during viral infection, which otherwise would prompt an antiviral immune response from infected cells, said Baylor College of Medicine... view more (2008-11-06)

Proteomics Study Yields Clues As To How Tuberculosis Might Be Thwarting The Immune System
A link between the immune system and the self-cleaning system by which biological cells rid themselves of obsolete or toxic parts may one day yield new weapons in the fight against tuberculosis and other deadly infectious diseases.   view more (2008-11-06)

Parasites that live inside cells use loophole to thwart immune system
St. Jude Children's Research Hospital scientists have discovered a mechanism by which intracellular pathogens can shut down one of the body's key chemical weapons against them: nitric oxide.   view more (2008-11-04)

Previously unknown immune cell may help those with Crohn's and colitis
The tonsils and lymphoid tissues in the intestinal tract that help protect the body from external pathogens are the home base of a rare immune cell newly identified by researchers at Washington University School of Medicine in St. Louis.   view more (2008-11-04)

Moores UCSD Cancer Center studying novel leukemia vaccine for high-risk patients
Researchers at the Moores Cancer Center at the University of California, San Diego (UCSD) are conducting clinical trials of a novel therapy aimed at revving up the immune system to combat a particularly difficult-to-treat form of leukemia.   view more (2008-11-04)

Lung airway cells activate vitamin D and increase immune response
Vitamin D is essential to good health but needs to be activated to function properly in the human body. Until recently, this activation was thought to happen primarily in the kidneys, but a new University of Iowa study finds that the activation step can also occur in lung airway cells.   view more (2008-11-04)

A double-barreled immune cell approach for neuroblastoma
Adding an artificial tumor-specific receptor to immune system cells called T-lymphocytes that target a particular virus extended and improved the cells' ability to fight a form of childhood cancer called neuroblastoma, said researchers form Baylor College of Medicine and Texas Children's Hospital... view more (2008-11-03)

Persistent bacterial infection exploits killing machinery of immune cells
A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them. This discovery may lead to new treatments and vaccines for tuberculosis (TB) and certain other chronic... view more (2008-11-03)

Substance tackles skin cancer from 2 sides
By playing it safe and using a two-pronged attack, a novel designer molecule fights malignant melanoma. It was created and tested by an international team of researchers led by the University of Bonn.   view more (2008-11-03)
