Scientists discover two HIV variants in cerebrospinal fluid of HAD patients

When the virus that causes AIDS infects the central nervous system, it can lead to the development of a severe neurological disease called HIV- associated dementia.

Lipomannan on TB bacterium's outer cell surface can block TNF production

The bacterium that causes tuberculosis has a unique molecule on its outer cell surface that blocks a key part of the body's defense. New research suggests this represents a novel mechanism in the microbe's evolving efforts to remain hidden from the human immune system.

Researchers discover cell differentiation mechanism

Researchers from the Haematopoietic Differentiation and Stem Cell Biology group at the Centre for Genomic Regulation (CRG), have described one of the mechanisms by which a cell (from the skin, for example) can be converted into another which is completely different.

MDC researchers determine molecular structure of dynamin

Dr. Katja F-lber and Professor Oliver Daumke, structural biologists at the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch, together with researchers from Freie Universit-t (FU) Berlin, have determined the molecular structure of dynamin, a 'wire-puller' that mediates nutrient uptake into the cell.

Immune system uses zinc to destroy tuberculosis bacillus, E. coli

A new natural defense mechanism against infections has been evidenced by an international team led by researchers from CNRS, Inserm, the Institut Pasteur and the Université Paul Sabatier - Toulouse III.

New insight into how nervous system regulates immunity

Scientists have identified a surprising new role for a new type of T cell in the immune system: some of them can be activated by nerves to make a neurotransmitter (acetylcholine) that blocks inflammation. The discovery of these T cells is novel and suggests that it may be possible to treat inflammation and autoimmune diseases by targeting the nerves and the T cells. The study was published this week in Science.

Study finds biological indicators that help explain why obese people develop chronic diseases

UC Davis Health System researchers have discovered biological indicators that help explain why some obese people develop chronic diseases such as diabetes and heart disease, and others do not.

Single-molecule imaging reveals how cells prepare to interact with biochemical signals

Researchers at Harvard Medical School have discovered that structural elements in the cell play a crucial role in organizing the motion of cell-surface receptors, proteins that enable cells to receive signals from other parts of the organism.

Prior parasitic worm infections may complicate TB therapy

Tuberculosis (TB) is a major threat to global health, taking the lives of more than a million people worldwide each year. Its greatest impact is often in the most impoverished places on earth, where patients frequently suffer from multiple chronic illnesses at the same time. In such situations, the question of whether each individual illness might make concurrent illnesses more difficult to treat becomes a critical issue both for specific patients and for general public health.

Researchers document how immune system can counteract advancement of Alzheimer's

For the first time a research team at Charité - Universitätsmedizin Berlin and Universitätsklinik Freiburg succeeded in documenting how the immune system can counteract the advancement of Alzheimer's disease.

Researchers demonstrate contribution of Immunoglobulin E to atherogenesis

There is an observed correlation between Immunoglobulin E (IgE) levels atherosclerosis, with twice amount of IgE present in patients with acute myocardial infarction as in patients with stable angina or without coronary heart disease (CHD). Guo-Ping Shi, DSc, Jing Wang, MD, PhD, and colleagues in the Department of Medicine at Brigham and Women's Hospital (BWH), have demonstrated the direct participation of IgE in atherogenesis in a mouse model.

Novel link between two receptors mediates fungal recognition in macrophages

Whitehead Institute researchers have uncovered a novel association between two fungal recognition receptors on the surface of certain immune cells, called macrophages.

Azithromycin may predispose cystic fibrosis patients to mycobacterial infection

Azithromycin is an antibiotic that also has antiinflammatory properties. It is these antiinflammatory properties that are thought to account for the improvement in clinical outcome observed when patients with chronic lung diseases such as cystic fibrosis are treated long-term with azithromycin.

Diabetes drug rosiglitazone can reduce development of neuropathic pain

The diabetes drug rosiglitazone (Avandia) can control inflammation leading to nerve damage and abnormal pain responses, suggests a paper in the August issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society.

Treatment with estrogen dramatically lowers rates of stomach cancer in male mice

Several types of cancer, including stomach, liver and colon, are far more common in men than in women. Some scientists have theorized that differences in lifestyle, such as diet and smoking, may account for the discrepancy, but growing evidence suggests that the differences are rooted in basic biological differences between men and women.
