Analysis of Fcg Receptor haplotypes in rheumatoid arthritis

People with a specific combination of variants of two genes, encoding two different receptors for the antibody Fc gamma, are three times more likely to develop rheumatoid arthritis than individuals with different variant combinations.

Compound from Salinispora (marine bacteria) kills blood cancer cells

An anti-cancer compound derived from bacteria dwelling in ocean-bottom sediments appears in laboratory tests to be a potent killer of drug-resistant multiple myeloma cells, and potentially with less toxicity than current treatments, report Dana-Farber Cancer Institute researchers in the November issue of Cancer Cell.

Possible viral cause of Kawasaki disease identified

In an important discovery in infectious disease research, a team of scientists from Northwestern University has identified a possible viral cause of Kawasaki disease, the most common cause of acquired heart disease in children in developed nations.

Plant extract forskolin may lead to leukemia treatment

Scientists here have identified a new pathway in the progression of chronic myelogenous leukemia (CML). They also discovered that an extract from the root of a common ornamental plant can suppress the process.

Trichostatin A may fight lupus and atherosclerosis simultaneously

People with lupus are prone to premature accelerated atherosclerosis. Now scientists at Wake Forest University School of Medicine think they have a way to prevent or decrease this atherosclerosis and prevent heart attacks.

FLT-1 blockers, cutting the legs of leukaemia

Leukaemia is characterised by an uncontrolled growth of abnormal blood cells in the bone marrow (BM).

Scientists discover why lung, but not skin, anthrax infections are lethal

Scientists from the Max Planck Institute for Infection Biology in Berlin discovered why lung, but not skin, anthrax infections are lethal. As reported in the newest issue of PloS Pathogen (November 2005) Neutrophils, a form of white blood cells, play a key role in anthrax infections.

Study proves the effectiveness of Vfend for the treatment of candidemia

Using Vfend (voriconazole) for the treatment of nonneutropenic patients with candidemia, an often-fatal hospital-acquired bloodstream infection, is as effective as a regimen of two older antifungals and carries fewer serious side effects than that regimen.

Unique approach to enhance the immune system in patients with breast or colorectal cancer

The study uses a potent immune-enhancing gene delivered directly into the cancer cells to make them look foreign to the body's immune system, which will then attack and destroy the cancer.

$107.6 million grant for malaria vaccine candidate

In an important step toward developing an effective malaria vaccine, the Bill & Melinda Gates Foundation has announced a $107.6 million grant to the PATH Malaria Vaccine Initiative (MVI) to extend the public-private partnership between MVI and GlaxoSmithKline Biologicals (GSK Bio) to develop GSK Bio's malaria vaccine for children in Africa.

New approaches to counteract platelet shortages

Availability of safe platelets is a fundamental blood transfusion challenge and can be especially problematic in times of emergency. Several studies presented at the annual American Association of Blood Banks (AABB) meeting today demonstrate new approaches to counteract platelet shortages by enhancing the safety of whole blood derived platelets, precluding the need to rely on only those obtained through apheresis.

Possible explanation for the higher incidence of lung cancer in African Americans

Faulty cell cycle "checkpoints" that fail to respond to DNA damage effectively may contribute to the high incidence of lung cancer in African-Americans, say researchers at Georgetown University's Lombardi Comprehensive Cancer Center and the National Cancer Institute (NCI).

Why breast black cancer patients experience lower survival rates than other women

Black women with stage I or II breast cancer are more likely than their counterparts of other races to abandon chemotherapy before completing their full course of treatment, according to a recent Columbia University Medical Center study.

New fungal defensin, plectasin, possesses as much power as penicillin

A peptide identified in a fungus found in northern European pine forests possesses as much power as penicillin as well as vancomycin, according to an international team of researchers.

New discoveries help explore the function of regulatory T cells in autoimmune disease and in cancer

More than 150 years after the discovery of Hassall's corpuscles in 1849, the function of these round blobs of cells in the human thymus gland has now been explained. The answer, in turn, ends an intense hunt for the origin of regulatory T cells that has been under way for years.

Gut antibody could prove to be a promising drug target for Crohn's disease

A collaboration led by the Burnham Institute for Medical Research has found that an antibody which binds to an unusual sugar molecule residing in the gut halts the inflammation seen in Crohn's disease and other intestinal inflammations. The antibody could prove to be a promising drug target for these common chronic intestinal disorders.

New role for the blood protein serum amyloid P in the body's response to medical materials

Using a technique called proteomics, the researchers identified many of the blood proteins that stick (adsorb) to the surfaces of medical devices. Blood proteins that adsorb to the surfaces of materials unfold and can be recognized by the body, which then mounts a response against the device.

Kidney paired donation transplantation has graft survival rates equivalent to compatible live donor transplants

A preliminary study suggests that kidney paired donation transplantation, in which incompatible donor/recipient pairs exchange kidneys so that each recipient receives a compatible kidney, had graft survival rates equivalent to compatible live donor transplants, according to a study in the October 5 issue of JAMA: The Journal of the American Medical Association.

Discovery of molecular roots of asthma, arthritis, and multiple sclerosis

The molecular roots of inflammatory and autoimmune diseases such as asthma, arthritis, and multiple sclerosis (MS) have been discovered by a team of researchers led by The University of Texas M. D. Anderson Cancer Center. They say their findings may point to ways to effectively treat these diseases - if not stop them before they start.
