Novel concept in chronic lymphoid leukemia treatment

Mayo Clinic researchers say they have moved closer to their goal of providing personalized care for a common blood cell cancer.

Gene research sheds light on T-cell production

New research, just published by researchers from the University of Georgia, provides the first evidence that a key gene may be crucial to maintaining the production of the thymus and its disease-fighting T-cells after an animal's birth.

Scientists at MIT create backpacks for cells which deliver chemotherapy agents

MIT engineers have outfitted cells with tiny "backpacks" that could allow them to deliver chemotherapy agents, diagnose tumors or become building blocks for tissue engineering.

Newly discovered protein may help explain tuberculosis' resiliency

Weill Cornell scientists have located a protein produced by the tuberculosis bacterium that may tell researchers more about how the invader lives so resiliently inside of the body.

Proteomics provides clues to how tuberculosis thwarts 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.

H5N1 protein hides in tiny tubules

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 researchers in an online report in the journal Nature.

Largest analysis of differences between human and chimpanzee genomes

Researchers have carried out the largest study of differences between human and chimpanzee genomes, identifying regions that have been duplicated or lost during evolution of the two lineages.

Anti-brain tumor agent derived from herpes virus passes next hurdle

An anti-brain tumor agent developed from a genetically engineered herpes simplex virus has been shown to be safe when given in two doses and injected directly into the brain of patients with malignant glioma.

10 symptoms that should never be ignored

Not every ache and pain merits a quick trip to the doctor -- but some do.

Scientists show how body regulates mature B-cells levels

Researchers at the University of Pennsylvania School of Medicine can now explain how the body determines whether there are enough mature B-cells in the blood stream at any one time.

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.

'Natural killer' immune cells reveal factors for reproductive success

Immune cells known as natural killer (NK) cells are linked with pregnancy problems including pre-eclampsia and recurrent miscarriage. Collaborative research between scientists at the Babraham Institute and Centre for Trophoblast Research in Cambridge is illuminating the role that pregnancy-related NK cells play in moderating the biochemical interactions at the boundary between maternal tissues and the developing foetus.

New findings on STEP HIV vaccine trial

The study is the result of the collaboration between scientists at the Institut de Genetique Moleculaire de Montpellier, Universite Montpellier I & II, Montpellier, France, the Centre Hospitalier Universitaire Vaudois (CHUV) and at the Swiss Vaccine Research Institute, University of Lausanne, Lausanne, Switzerland.

Scientists step closer to finding a defense against superbugs

A discovery from the Oklahoma Medical Research Foundation has put scientists are one step closer to finding a defense against dangerous antibiotic-resistant bacteria, sometimes called "superbugs."

Rare 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.

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.

Novel leukemia therapy shows promise 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.

Study shows how HIV-1 vaccine trial could have enhanced HIV infection

In September 2007, a phase II HIV-1 vaccine trial was abruptly halted when researchers found that the vaccine may have promoted, rather than prevented, HIV infection.

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. The researchers found that the microbes block nitric oxide production by subverting the biochemical machinery used by immune cells called macrophages to produce the chemical.

Researchers develop DNA vaccine for West Nile virus

Researchers are developing a DNA-based vaccine against the dreaded West Nile virus (WNV), which can be transmitted from animals to humans. The unique feature of this vaccine is that it is also effective after onset of the disease, for it has therapeutic properties.
