New treatment options for leukemia and myeloproliferative disorders introduced

Leukemia and myeloproliferative disorders are serious and often deadly blood cancers. Research presented today at the 51st Annual Meeting of the American Society of Hematology introduces potential new treatment options and improved diagnostic methods for patients suffering from acute promyelocytic leukemia, chronic myeloid leukemia, infant acute lymphoblastic leukemia, and myelofibrosis that are based on a better understanding of the underlying genetic causes of these conditions.

Findings suggest severity of atherosclerosis depends on the rate of white blood cell migration

By measuring the total gene activity in organs relevant for coronary artery disease (CAD), scientists at the Swedish medical university Karolinska Institutet have identified a module of genes that is important for the recruitment of white blood cells into the atherosclerotic plaque.

Scientists discover mechanism by which E6 oncoprotein of high-risk HPV16 promotes carcinogenesis

In the 1980s, Harald zur Hausen and his co-workers discovered that specific types of human papillomavirus (HPV) cause cervical cancer. Scientists soon found out how these pathogens cause cells to degenerate. It is known today that the main culprits are viral proteins E6 and E7. Both proteins switch off different cellular control functions, thus promoting cell growth.

New approach to identify molecules that prevent immune cells from attacking body

A study led by a Scripps Research Institute scientist describes a new, highly pragmatic approach to the identification of molecules that prevent a specific type of immune cells from attacking their host. The findings add a powerful new tool to the ongoing search for potential treatments for autoimmune diseases, such as multiple sclerosis (MS), as well as blood cancers, such as myeloid leukemia.

Sperm genes may have a detrimental effect on longevity, says new study

Researchers in Japan have found that female mice produced by using genetic material from two mothers but no father live significantly longer than mice with the normal mix of maternal and paternal genes. Their findings provide the first evidence that sperm genes may have a detrimental effect on lifespan in mammals.

Research shows link between nervous and immune systems; findings may lead to new treatments for autoimmune disorders

New research in the Journal of Leukocyte Biology shows the link between the nervous and immune systems and how breaking that link might lead to new treatments for a wide range of autoimmune disorders

University of Navarra Hospital launches clinical trials to assess the efficacy of immunotherapy treatment

The University of Navarra Hospital has launched a series of clinical trials in order to assess the efficacy of an immunotherapy treatment. This approach involves the application of personalised vaccines -produced from healthy and tumour cells from the patient him or herself- and designed to combat glioblastomas, one of the most aggressive and frequent malignant tumours.

Clinical trials of personalised vaccines to fight glioblastomas

The University of Navarra Hospital has launched a series of clinical trials in order to assess the efficacy of an immunotherapy treatment. This approach involves the application of personalised vaccines —produced from healthy and tumour cells from the patient him or herself— and designed to combat glioblastomas, one of the most aggressive and frequent malignant tumours.

NIGMS invests $42.3 million in "Grand Opportunities" grant

The National Institute of General Medical Sciences (NIGMS), part of the National Institutes of Health (NIH), is investing $42.3 million for grants in scientific areas it identified as "Grand Opportunities (GO)." NIH developed the GO grant program to stimulate biomedical research and the economy using funds provided by the American Recovery and Reinvestment Act (Recovery Act).

Scientists discover new potential target for treating non-Hodgkin's lymphoma

Physician-scientists from Weill Cornell Medical College have discovered a molecular mechanism that may prove to be a powerful target for the treatment of non-Hodgkin's lymphoma, a type of cancer that affects lymphocytes, or white blood cells. By exploiting this mechanism, researchers have been able to powerfully suppress tumor formation in lab testing and in animal models.

Discovery of Th22 cells may help in developing effective therapies for chronic skin and respiratory diseases

The newly discovered Th22 cells are a previously unknown subset of T helper cells. T helper cells are white blood cells that help activate other immune cells when the body is infected by viruses or bacteria. At the same time they help the body to tolerate own tissue and to prevent or curb inflammation.

MPI scientists identify mechanism that demonstrates immune cell movement on diverse surfaces

Scientists from the Max Planck Institute (MPI) of Biochemistry in Martinsried near Munich, Germany, have now deciphered the mechanism that illustrates how these mobile cells move on diverse surfaces. "Similar to a car, these cells have an engine, a clutch and wheels which provide the necessary friction," explains Michael Sixt, a research group leader at the MPI of Biochemistry.

Verax Platelet PGD test receives FDA clearance

Fenwal, Inc., a global medical technology company focused on improving blood collection, separation, safety and availability, announced today that the U.S. Food and Drug Administration has cleared the Verax Platelet PGD® test as a quality control test to detect bacterial contamination in whole blood-derived, pooled platelets prior to transfusion. Fenwal is the exclusive global distributor of the test, which was developed by Verax Biomedical of Worcester, Mass.

Previous flu infections can reduce the severity of H1N1

Researchers at the La Jolla Institute for Allergy & Immunology have found that previous influenza infections may provide at least some level of immunity to the H1N1 "swine" flu. "The question we asked was, "Is the swine flu more like the seasonal flu or like a totally new strain of influenza where there would be no immunity?," said Alessandro Sette, Ph.D., an internationally recognized vaccine expert and director of the La Jolla Institute's Center for Infectious Disease.

Th22 cell to control inflammation in body to help fight off infection discovered

A new type of immune cell that can be out of control in certain chronic inflammatory diseases, worsening the symptoms of conditions like psoriasis and asthma, is described for the first time in the Journal of Clinical Investigation.

Antioxidant found in vegetables can protect cells from damage caused by infection and injury

Scientists at the University of Pennsylvania School of Medicine discovered that a dietary antioxidant found in such vegetables as broccoli and cauliflower protects cells from damage caused by chemicals generated during the body's inflammatory response to infection and injury. The finding has implications for such inflammation-based disorders as cystic fibrosis (CF), diabetes, heart disease, and neurodegeneration.

Hope for vaccine against Chlamydia

"Now that we know how the body defends itself against the Chlamydia bacteria, we can develop a vaccine that optimises that defence. We have a basic understanding of how the vaccine could work, but some work remains to be done. We believe that it will take a few years before the vaccine becomes a reality," says researcher Ellen Marks, the author of the thesis.

NIDA supports new drug detection research

Every time a person snorts cocaine, it doesn't just go to his or her head: It also provokes a response in the immune system, creating special biomolecules that may serve as a permanent record of each exposure.

New technique to identify patients more likely to survive advanced melanoma

Although the chances of surviving advanced melanoma aren't very good with current therapies, some patients can live for years with cancer that has spread beyond the skin to other organs. Now it may be possible to identify which patients are more likely to survive by analyzing the activity of hundreds of genes involved in the immune response and gene proliferation, according to researchers at NYU Langone Medical Center.

FDA approves Istodax for treatment of Cutaneous T-cell Lymphoma

The U.S. Food and Drug Administration has approved Istodax (romidepsin), an injectable medication, for treatment of patients with a rare form of cancer known as Cutaneous T-cell Lymphoma (CTCL).
