Investigative drug hampers the survival of non-Hodgkin lymphoma cells

An investigative drug deprived non-Hodgkin lymphoma cells of their ability to survive too long and multiply too fast, according to an early study published recently in the journal Experimental Hematology.

Master gene could lead to new ways of cancer treatments

The master gene that causes blood stem cells to turn into disease-fighting 'Natural Killer' (NK) immune cells has been identified by scientists, in a study published in Nature Immunology today. The discovery could one day help scientists boost the body's production of these frontline tumour-killing cells, creating new ways to treat cancer.

Insects can be used to test the efficiency of new drugs

Insects, such as some moths and fruit flies, react to microbial infection in the same way as mammals and so can be used to test the efficiency of new drugs, thereby reducing the need for animal testing. Dr Kevin Kavanagh from the National University of Ireland - Maynooth, presented his research findings at the Society for General Microbiology's meeting at Heriot Watt University, Edinburgh, today (8 September).

Study identifies key compound that quickens recovery from life-threatening blood cell shortages

A key compound resupplies bone marrow with fast-acting stem cells that can more quickly rekindle blood cell production, according to a study published online today in the journal Blood. While the study was in mice, in the study authors say it has the potential to increase survival among patients with life-threatening blood cell shortages.

New ARRA-funded research on white blood cell functioning

The American Recovery and Reinvestment Act (ARRA) has provided funding for new research to learn more about how white blood cells work. Jonathan Reichner, PhD, of the department of surgery at Rhode Island Hospital has received a grant from the National Institutes of Health with funding through the American Recovery and Reinvestment Act. Reichner's hope is that the research will lead to new immune-enhancing therapies, with potential implications for improvements in both cancer treatment and controlling inflammation accompanying injury and infection.

NIAID to establish a human immune profiling research consortium in 2010; invites grant applications

The National Institute of Allergy and Infectious Diseases (NIAID), a component of the National Institutes of Health, is accepting grant applications for a new initiative to establish a consortium of human immune profiling research centers.

Study finds long-term exposure to progesterone may lead to growth of tumors

Scientists at Michigan State University have found exposure to the hormone progesterone activates genes that trigger inflammation in the mammary gland.

FDA approves Extavia for multiple sclerosis

The US Food and Drug Administration (FDA) has approved Extavia(R) (interferon beta-1b), the first in a new planned portfolio of multiple sclerosis (MS) medicines from Novartis to help patients manage this devastating disease.

New immune therapy for kidney cancer tested

Researchers at The Cancer Institute of New Jersey (CINJ) have opened a clinical trial to evaluate whether the standard treatment for a common form of kidney cancer works better by itself or when combined with a certain type of blood cell that comes from a patient’s relative. CINJ is a Center of Excellence of UMDNJ-Robert Wood Johnson Medical School.

Experimental treatment for multiple sclerosis reverses disorder in mice

A new experimental treatment for multiple sclerosis (MS) completely reverses the devastating autoimmune disorder in mice, and might work exactly the same way in humans, say researchers at the Jewish General Hospital Lady Davis Institute for Medical Research and McGill University in Montreal.

Cost effectiveness study looks at potential value of new genetic test for guiding chemotherapy treatment

For the 29,000 patients in the United States with metastatic colorectal cancer, chemotherapy with irinotecan is a standard treatment that has been shown to improve survival. But for more than one in 10 of these patients, a variation in their DNA means that this treatment could result in a severe reduction in their white blood cell count, leading to a high risk of bacterial infection and possible subsequent death.

Discovery of gene linked to follicular lymphoma

California and Arizona researchers have identified a gene variant that carries nearly twice the risk of developing an increasingly common type of blood cancer, according to a study published online today by the science journal Nature Genetics.

Gene variants associated with survival advantage in African Americans with HIV

From the start of the HIV epidemic, it appeared that some of the people who were infected with the virus were able to ward off the fatal effects of the disease longer than others.

Hydrogen peroxide marshals immune system

When you were a kid your mom poured it on your scraped finger to stave off infection. When you got older you might have even used it to bleach your hair. Now there's another possible function for this over-the-counter colorless liquid: your body might be using hydrogen peroxide as an envoy that marshals troops of healing cells to wounded tissue.

Abraxane prolongs survival in metastatic breast cancer

Research from the Northwestern University Feinberg School of Medicine has found that a less toxic, solvent-free chemotherapy drug more effectively prevents the progression of metastatic breast cancer and has fewer side effects than a commonly used solvent-based drug.

FDA approves Avastin (bevacizumab) for treatment of glioblastoma multiforme

The U.S. Food and Drug Administration recently approved Avastin (bevacizumab) to treat patients with glioblastoma multiforme (GBM) when this form of brain cancer continues to progress following standard therapy.

Study reveals current multi-component vaccines may need reworking

Current strategies for designing vaccines against HIV and cancers, for instance, may enable some components in multi-component vaccines to cancel the effect of others on the immune system, eliminating their ability to provide protection, according to an article to be published shortly in the Proceedings of the National Academy of Sciences (PNAS).

Oral delivery system for RNAi therapeutics

Researchers at the University of Massachusetts Medical School (UMMS) report on a novel approach to the delivery of small bits of genetic material in order to silence genes using "RNA interference"-and in the process, discovered a potent method of suppressing inflammation in mice similar to what occurs in a range of human diseases.

Discovery of molecule that could improve success of blood stem cell transplants

University of British Columbia researchers have discovered a "molecular key" that could help increase the success of blood stem cell transplants, a procedure currently used to treat diseases such as leukemia, Hodgkin's lymphoma and aplastic anemia.

Chronic lymphocytic leukemia linked to seven different gene variants

A national team of researchers led by Mayo Clinic has found that patients with chronic lymphocytic leukemia (CLL) are more likely to have similar DNA changes or variants in up to six genes, compared to people who do not have the cancer.
