Role of IL-24 in regulating the immune system

Researchers at Introgen Therapeutics and their collaborators at The University of Texas M. D. Anderson Cancer Center have published new findings on the role of IL-24 in regulating the immune system in the current online issue of the Journal of Leukocyte Biology.

Moraxella catarrhalis found to be responsible for 10 percent of exacerbations of COPD

A ubiquitous bacterial strain thought to be uninvolved in chronic obstructive pulmonary disease (COPD) in fact is responsible for 2-4 million flare-ups of the condition that occur annually in the United States, researchers from the University at Buffalo have shown.

Results demonstrate the safety and tolerability of ABthrax treatment for Anthrax infection

Human Genome Sciences has announced that results published in the current issue of Clinical Infectious Diseases demonstrate that the first investigational agent against anthrax infection to be evaluated in a clinical study since the 2001 anthrax attacks in the United States, is safe, well tolerated and achieves the blood levels predicted by relevant animal models as necessary to afford significant protection from the lethal effects of the anthrax toxin

Minimally invasive colorectal surgery may have a less pronounced inflammatory response

Minimally invasive colorectal surgery may have a less pronounced inflammatory response and less of a suppressing effect on the immune system than conventional surgery, resulting in a possible reduction in post-operative complications, according to a study in the July issue of Archives of Surgery.

Scientists have begun to clarify how one of the body's molecules controls the trafficking of T cells through the blood

...lymph nodes and on to tissues to fight infection -- a crucial response that sometimes goes awry, attacking the body's own tissues and causing autoimmune diseases.

Novel treatment for ovarian cancer

The Tulane University Section of Hematology and Medical Oncology is investigating a novel treatment for ovarian cancer by using intravenous Ontak to deplete harmful cells that inhibit the body's natural immune response to fight cancer. Ovarian cancer is the fifth leading cancer killer of women in the United States.

Newly discovered gene mutation may account for many cases of immune deficiency

...in particular two syndromes known as immunoglobulin A (IgA) deficiency and Common Variable Immunodeficiency (CVID), report researchers in the July issue of Nature Genetics. The discovery may lead to a new diagnostic test for these conditions, which make people highly susceptible to infections and often go unrecognized because of a lack of good tests.

Scientists discover how an HIV protein fragment shuts down an immune response

The HIV virus hides out in the very immune system cells that are meant to protect the body from viral infection. But how does it prevent these cells from mounting a full-scale attack against the invader?

Researchers clarifiy role of Notch protein in T-cell development

Researchers at the University of Pennsylvania School of Medicine have recently clarified the role of the Notch protein in T-cell development. T cells are required for many aspects of immunity, including fighting viral infections, providing cancer surveillance, and regulating multiple aspects of the immune response.

Enzyme known as cathepsin G may be a target for anti-inflammatory treatments

The finding by researchers at Washington University School of Medicine in St. Louis shows that an enzyme known as cathepsin G regulates the ability of immune cells known as neutrophils to secrete chemicals that attract other immune cells and start the local inflammatory process. Over time, the excessive accumulation of immune cells can lead to tissue and cartilage damage in joints, causing pain and limiting mobility.

OHSU scientists say low FOXP3 means fewer disease-fighting cells, but new drug may help multiple sclerosis

Oregon Health & Science University researchers have measured genetic changes reflecting a drop in the body's ability to suppress inflammatory cells that attack nerve fibers and promote progression of multiple sclerosis.

New insight into autoimmune disease

The immune system is a complex and powerful weapon that provides protection against bacteria and viruses that, if left unchecked, would wreak havoc throughout the human body.

Harmless bacterium can sometimes trigger outbreaks of life-threatening meningitis

Reporting in the June 20 issue of The Journal of Experimental Medicine, a group of scientists in Paris, France led by Colin Tinsley may have discovered how a normally harmless bacterium can sometimes trigger outbreaks of life-threatening meningitis.

Female bed-rest study will understand changes to the immune response and decreased resistance to infection in space

A bed-rest study with female participants will help scientists understand changes to the immune response and decreased resistance to infection in space.

Findings may help scientists improve the existing vaccine for yellow fever

In one of the first molecular studies of the human antibody response to yellow fever, Howard Hughes Medical Institute (HHMI) researchers and their colleagues have found the crucial bit of virus that people's immune systems need to spot and quash this often-fatal re-emerging disease.

Immune system discovery could help in the treatment of bowel cancer

Scientists investigating whipworms, parasites that infect one-fifth of the world's population as well as livestock and domestic animals, have discovered a new way that the body effectively eliminates the parasites.

Protocol used to treat the first known survivor of rabies without prior vaccination published

The protocol used to treat the first known survivor of rabies without prior vaccination is published in the June 16, 2005, issue of the New England Journal of Medicine. It is hoped that this approach can be replicated, tested, and provide a guide for treating this fatal condition, especially in parts of the world where the incidence of rabies is rampant.

Nanotechnology used to smuggle a powerful chemotherapeutic drug inside tumor cells

University of Michigan scientists have created the nanotechnology equivalent of a Trojan horse to smuggle a powerful chemotherapeutic drug inside tumor cells - increasing the drug's cancer-killing activity and reducing its toxic side effects.

Chemotherapy for brain tumors is boosted after vaccine targets resistance-related TRP-2 antigen

In the August issue of the journal Oncogene, researchers at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute describe a molecular mechanism that appears to make malignant brain tumors more vulnerable to chemotherapy after they have been treated with the dendritic cell vaccine.

Researchers may be on the verge of exploiting the vulnerabilities of a virus that causes cervical cancer

Researchers may be on the verge of exploiting the vulnerabilities of a virus that causes cervical cancer, thanks to a newly developed technique that enables scientists to mass-produce human papillomavirus (HPV) in the laboratory.
