Study explores role of genetic influence on ulcerative colitis

Adults diagnosed with ulcerative colitis after age 50 are more likely to achieve remission from their symptoms than patients diagnosed at younger ages, even when those patients receive similar treatments, according to research at Washington University School of Medicine in St. Louis.

Alphavirus vector induce immune responses in people with advanced cancer: Researchers

There are several challenges to be overcome if therapeutic anticancer vaccines, which are designed to boost the patient's anticancer immune response, are to be successfully developed. For example, the viruses used to deliver the tumor protein to the patient's immune system are themselves targeted by the patient's immune system, inducing neutralizing and suppressive responses. But now, a team of researchers, led by Michael Morse, at Duke University Medical Center, Durham, has developed a way to overcome these neutralizing and suppressive responses by using an alphavirus packaged in virus-like replicon particles.

Alphavirus vaccine blocks tumor growth in advanced cancer: Research

An experimental vaccine based on a virus that causes encephalitis in the wild appears to block tumor growth in some cases of advanced cancer, according to researchers at Duke University Medical Center. Scientists say the vaccine is able to stimulate an immune response, even in the face of profound immune system suppression, a condition most patients with advanced cancer experience.

WHO expert: Faster MDR-TB test should be made available to vulnerable populations

A new diagnostic tool that shortens the diagnosis of multidrug-resistant tuberculosis (MDR-TB) from eight weeks to two hours should be made available to vulnerable populations according to a WHO expert, Reuters reports.

CD74 can serve as prognostic marker for colorectal cancer

CD74 is a protein that is expressed in and on cells of the immune system, such as B lymphocytes and antigen presenting cells. This protein is known for its function in facilitating antigen presentation enabling the immune response. Additionally, Professor Shachar's lab has previously shown that CD74 serves as a survival receptor on cells of the immune system, and that its stimulation by its natural ligand -migration inhibitory factor (MIF)- prevents apoptosis (self destruction) of these cells. It was shown that CD74 is markedly expressed on numerous tumors - hematologic as well as epithelial, and can serve as a prognostic marker. CD74's expression and function on colon intestinal epithelial cells is controversial.

Loss of key nerve cells cause Parkinson's disease: Research

Scientists at the Stanford University School of Medicine have identified a molecular pathway responsible for the death of key nerve cells whose loss causes Parkinson's disease. This discovery not only may explain how a genetic mutation linked to Parkinson's causes the cells' death, but could also open the door to new therapeutic approaches for the malady.

Etubics enters Phase I trials for next generation vector vaccines

Etubics Corporation, a biopharmaceutical company developing next generation vector vaccines, has entered into Phase I trials at Duke University with its ETBX-011, a therapeutic vaccine candidate that is intended to treat Carcinoembryonic Antigen expressing cancers such as colorectal cancer. Etubics dosed its first patient yesterday. Etubics was recently granted clearance by the U.S. Food and Drug Administration for its Investigational New Drug application to begin studying ETBX-011 in humans.

BiondVax receives 2010 European Influenza Vaccines Technology Innovation Award

Frost & Sullivan is pleased to announce the award of its prestigious 2010 European Influenza Vaccines Technology Innovation Award to BiondVax Pharmaceuticals for their breakthrough work on a universal influenza vaccine. This vaccine, the Multimeric-001, is designed to provide multi-season and multi-strain protection against most influenza virus strains, including both seasonal and pandemic strains, and has the potential to eliminate the need for annual flu vaccination. BiondVax is entering Phase II clinical trials for the development of the Multimeric-001 universal influenza vaccine.

Antigenics announces positive results of AG-707 genital herpes vaccine

Antigenics announced positive results with AG-707, an investigational therapeutic vaccine being developed to treat herpes simplex virus-2,the virus that causes genital herpes, in infected patients. Developed by Antigenics, the vaccine triggers a cellular immune response, stimulating both CD4+ and CD8+ T cells.

Nano-patch to replace needles for vaccination soon: Study

Those who fear needles have good news awaiting them. Australian researchers have developed a new method of vaccine delivery using needle-free nano-patches. These could also be mailed to people during pandemics. This breakthrough is published in the latest edition of the journal Small.

Neu5Gc in drugs provokes strong immune response

Researchers at the University of California, San Diego School of Medicine have discovered that a kind of sugar molecule common to chimpanzees, gorillas and other mammals but not found in humans provokes a strong immune response in some people, likely worsening conditions in which chronic inflammation is a major issue.

New model of inflammatory bowel disease explores interactions of cells in immune system

Scientists at the Virginia Bioinformatics Institute at Virginia Tech have constructed a mathematical and computational model of inflammatory bowel disease that allows researchers to simulate the cellular and molecular changes underlying chronic inflammation in humans. The model allows scientists to explore different interactions of cells in the immune system, check how these cells are linked to inflammation in the colon, and identify intervention points to perhaps stop the disease in its tracks.

Three toxins in food identified as triggers to gluten intolerance: study

Coeliac disease cause by intolerance to gluten present in food and drinks like bread, pasta, cereals, biscuits and beer commonly affects many people all over the world. This affects 1 percent of all people in UK, especially women. Patients are advised to stay away from gluten to prevent damage to their intestines. In spite of this in five years most patients develop problems in their intestines. A gluten free diet is also difficult to maintain. Possible symptoms include diarrhoea, nausea and vomiting, recurrent stomach pain, tiredness, headaches, weight loss and mouth ulcers. These may be mild, moderate or severe in different individuals.

Scientists identify key genes for Silk Road disease

Scientists have identified key genes responsible for a severe inflammatory disease that has spread along the old silk trading routes from the Far East to the edge of Europe.University of Manchester researchers, working as part of a large international consortium, have revealed some of the genetic mutations that lead to Behçet's disease. The group's findings are published in Nature Genetics.

Scientists develop new way to increase effectiveness of antiviral drugs

Scientists have developed a new way to target viruses which could increase the effectiveness of antiviral drugs.Instead of attacking the virus itself, the method developed at the University of Edinburgh alters the conditions which viruses need to survive and multiply.
