Brain's immune system may cause chronic seizures

Chronic seizures caused by traumatic head injuries may result from chemicals released by the brain's immune system attempting to repair the injured site, according to a study led by the University of Colorado at Boulder.

Future of organ transplantation - microscopic beads that create "designer " immune cells

The future of organ transplantation could include microscopic beads that create "designer" immune cells to help patients tolerate their new organ, Medical College of Georgia researchers say.

Lifespan of HIV-infected cells might be shorter than previously anticipated

Dutch-sponsored researcher Christian Althaus has used mathematical models to demonstrate that cells infected with HIV could live even shorter than was thought until now. If infected cells have a shorter lifespan then this increases the chances of the virus escaping the attention of the immune system.

Biomarker in urine for appendicitis

Appendicitis is the most common childhood surgical emergency, but the diagnosis can be challenging, especially in children, often leading to either unnecessary surgery in children without appendicitis, or a ruptured appendix and serious complications when the condition is missed.

Transplant drug Rapamycin stimulates immune memory

Rapamycin, a drug given to transplant recipients to suppress their immune systems, has a paradoxical effect on cells responsible for immune memory, scientists at the Emory Vaccine Center have discovered.

Chitosan and polyester ‘combo’ creates mixed-fiber material for nerve repair

In the clothing industry it's common to mix natural and synthetic fibers. Take cotton and add polyester to make clothing that's soft, breathable and wrinkle free.

Inflammation of microglia may not be associated with dementia in Alzheimer's disease

The idea that anti-inflammatory drugs might protect people struggling with dementia from Alzheimer's disease has received a blow with the online release of a study of human brain tissue in Acta Neuropathologica.

Discovery in dendritic cell signalling pathways pave way for new therapeutic targets

Scientists from A*STAR's Singapore Immunology Network (SIgN) and the University of Milano-Bicocca, Italy, have discovered another signaling pathway for the activation and apoptosis, or programmed cell death, of dendritic cells. This discovery was published in the advanced online publication of Nature on 15 Jun 2009.

Cancer immunotherapy can use small numbers of ‘stem-like’ immune cells to destroy large tumors in mice

A new approach to stimulating immune cells enhances their anticancer activity, resulting in a powerful anti-tumor response in mice, according to a study by researchers at the National Cancer Institute, a part of the National Institutes of Health. This work represents an important advance in the development of immunotherapy for cancer and appears online June 14, 2009 in Nature Medicine.

Declaration of H1N1 pandemic to accelerate H1N1 vaccine production

The WHO's decision Thursday to declare H1N1 (swine) flu a pandemic will "speed the production of a vaccine against the new virus," however scientists continue to caution that "it will be fall at the earliest before the first doses are available," the Los Angeles Times reports.

New insights into causes of multiple sclerosis

Over 100,000 people suffer from multiple sclerosis in Germany alone. Despite intensive research, the factors that trigger the disease and influence its progress remain unclear.

Mouse experiments shed light on age effects in arthritis

Older mice are more susceptible to proteoglycan-induced arthritis (PGIA). Researchers writing in BioMed Central's open access journal Immunity & Ageing have shown, for the first time, that young mice are completely resistant, but become fully susceptible to the disease with age.

Tuberculosis booster vaccine trials to begin next month In South Africa

A new two-year trial to test a tuberculosis vaccine aimed at boosting the efficacy of the BCG vaccine is scheduled to begin soon in South Africa, IRIN reports (IRIN, 6/4).

Cigarette smoking does not affect everyone in same way

Cigarette smoking induced COPD, or chronic obstructive pulmonary disease, is a disease that results in severe breathing difficulty. According to World Health Organization (WHO) it is the fourth leading killer worldwide. However the mechanisms responsible for some smokers developing COPD and others evading the disease have not been well understood.

Cancer vaccine efficacy enhanced using anti-diabetic drug Metformin

After a vaccination or an infection, the human immune system remembers to keep protecting against invaders it has already encountered, with the aid of specialized B-cells and T-cells. Immunological memory has long been the subject of intense study, but the underlying cellular mechanisms regulating the generation and persistence of long-lived memory T cells remain largely undefined. Now, University of Pennsylvania School of Medicine researchers have found that a common anti-diabetic drug might enhance the effectiveness of vaccines. The findings are described this week in an advanced online publication of Nature.

WHO closer to declaring H1N1 flu outbreak a pandemic

The WHO on Tuesday said it was "getting closer" to declaring the H1N1 (swine) flu outbreak to be a pandemic, as the virus continues to spread to people outside of North America, and in populations "as far apart as Britain, Spain, Japan, Chile and Australia," the AP/Washington Post reports (Jordans, AP/Washington Post, 6/2).

Smoking and genetics play role in rheumatoid arthritis

Recent genetic studies have revealed several new sites of genes that are risk factors for developing rheumatoid arthritis (RA).

Discovery of biochemical signals that help immune cells remember how to fight infection

Immunology researchers at UT Southwestern Medical Center have discovered how two biochemical signals play unique roles in promoting the development of a group of immune cells employed as tactical assassins.

DNA compounds show promise for Lupus

A research team led by a University of Iowa investigator has generated DNA-like compounds that effectively inhibit the cells responsible for systemic lupus erythematosus -- the most common and serious form of lupus. There currently is no cure for this chronic autoimmune condition that damages the skin, joints and internal organs and affects an estimated one million Americans.

Arthritis drug Abatacept may be effective in fighting the flu

Researchers at the University of Maryland School of Medicine have found that an approved drug for treating rheumatoid arthritis reduces severe illness and death in mice exposed to the Influenza A virus. Their findings suggest that tempering the response of the body's immune system to influenza infection may alleviate some of the more severe symptoms and even reduce mortality from this virus.
