Biomarkers in blood could aid diagnosis of two severe and debilitating forms of malaria

Canadian researchers have identified protein biomarkers that shed new light on the development of two severe and debilitating forms of malaria.

Promacta (eltrombopag) shown to increase platelet counts and reduce bleeding in chronic immune thrombocytopenic

GlaxoSmithKline has announced positive safety and efficacy results from RAISE (RAndomized placebo- controlled ITP Study with Eltrombopag), a Phase III study of Promacta (eltrombopag) in adults with chronic immune (idiopathic) thrombocytopenic purpura (ITP) who had received one or more prior ITP therapies.

Scientists pinpoint immune-system targets in complex pathogens

Our immune cells have an amazingly intricate recognition system to detect invading pathogens. Often, the intricacies have overwhelmed scientists who want to know exactly what gives an alarm signal to T cells, a class of white blood cells that recognizes invaders.

Zinc key to formation of hospital-acquired infections

Hospital-acquired infections that are resistant to traditional antibiotic treatment have become increasingly common in recent years, confounding health care professionals and killing thousands of Americans.

Well-armed immune cells help long-term non-progressors contain HIV

To help develop an effective HIV vaccine, researchers are trying to better understand how the immune systems of a small minority of HIV-infected people known as long-term non-progressors (LTNPs) contain the virus naturally.

Vitamin E supplementation may reduce inflammation in the brain

With up to half of a person's body mass consisting of skeletal muscle, chronic inflammation of those muscles - which include those found in the limbs - can result in significant physical impairment.

New insights into development of the human immune system

A UCSF study has found that a surprisingly high number of maternal cells enters the fetus during pregnancy, prompting the generation of special immune cells in the fetus that suppress a response against the mother.

Discovery of groundbreaking technique for body to accept gene therapy

Researchers at Columbia University Medical Center and the State University of New York at Stony Brook (SUNY) have developed a groundbreaking technique to sneak therapeutic genes past the body's defenses, possibly clearing one of the largest hurdles to realizing the potentials of medically altering a patient's DNA.

Extraordinary immune cells may hold the key to managing HIV

People who manage to control HIV on their own are providing scientists with valuable information about how the immune system eliminates virus-infected cells.

Cancer stem-cell model tested by University of Michigan researchers

One of the most promising new ideas about the causes of cancer, known as the cancer stem-cell model, must be reassessed because it is based largely on evidence from a laboratory test that is surprisingly flawed when applied to some cancers, University of Michigan researchers have concluded.

Scientists film immune cell becoming infected by a parasite

Forget what's number one at the box office this week. The most exciting new film features the intricate workings of the body, filmed by scientists using ground-breaking technology.

Natural killer T cells play important role in Lyme disease

A research team led by the La Jolla Institute for Allergy & Immunology and Albany Medical College has illuminated the important role of natural killer (NK) T cells in Lyme disease, demonstrating that the once little understood white blood cells are central to clearing the bacterial infection and reducing the intensity and duration of arthritis associated with Lyme disease.

Tobacco plants grown in novel mist bioreactor system provide new soure of interleukin-12

Interleukin-12 is a naturally occurring protein essential for the proper functioning of the human immune system.

Gene therapy used to alleviate sickle cell disease pathology

Using a harmless virus to insert a corrective gene into mouse blood cells, scientists at St. Jude Children's Research Hospital have alleviated sickle cell disease pathology.

New insights into cellular senescence

Scientists have identified a molecular cause behind the ravages of old age and in doing so have also shown how a natural process for fighting cancer in younger persons can actually promote cancer in older individuals.

Interferon needed for cells to 'remember' how to defeat a virus

Scientists at UT Southwestern Medical Center have determined that the immune-system protein interferon plays a key role in "teaching" the immune system how to fight off repeated infections of the same virus.

Study looks at 'vicious circle' theory infections in COPD patients

In treating flare-ups in chronic obstructive pulmonary disease (COPD), a major cause of disability and the fourth leading cause of death in the U.S, what was old is important again.

More evidence on why the Mediterranean diet is good for heart

Researchers have discovered one potential mechanism by which briefly cutting off, then restoring, blood flow to arteries prior to a heart attack lessens the damage caused, according to a study published today in the journal Cardiovascular Research.

Vitamin D enhances placental innate immunity

In a paper available at the online site of the journal Biology of Reproduction, a team of UCLA researchers reports for the first time that vitamin D induces immune responses in placental tissues by stimulating production of the antimicrobial protein cathelicidin.

New method improves immunotherapy

A study published by Elsevier this month in Clinical Immunology, the official journal of the Clinical Immunology Society (CIS), describes a new method that facilitates the induction of a specific type of immune suppressive cells, called 'regulatory T cells' for therapeutic use.
