Research on immune system may help develop improved vaccines for cancer

Researchers at the University of Cambridge hope to revolutionise cancer therapy after discovering one of the reasons why many previous attempts to harness the immune system to treat cancerous tumours have failed.

Scientists identify genes that enable some immune systems to halt HIV; finding could spur drug, vaccine development

Tiny variants in a protein that alerts the body to infection could explain how one in 300 HIV-infected people are able to resist the onset of AIDS for years without needing any treatment, researchers said Thursday in a study published online in the journal Science, Agence France-Presse reports

Bortezomib reduces inflammation and promotes bone healing in arthritis models

A new study by Greek researchers suggests that the biologic drug bortezomib (Velcade), a proteasome inhibitor used to treat multiple myeloma (bone marrow cancer), may represent a promising treatment for rheumatoid arthritis (RA). In this study, bortezomib displayed favorable effects in an animal model of inflammatory arthritis that mimics RA, in reducing disease severity and inflammation, and promoting bone healing. Full findings of this study are published in the November issue of Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR).

Researchers discover FoxO1 protein interacts with macrophages to promote inflammatory response

Researchers at the University of California, San Diego School of Medicine have discovered that a multi-tasking protein called FoxO1 has another important but previously unknown function: It directly interacts with macrophages, promoting an inflammatory response that can lead to insulin resistance and diabetes. Contrarily, it also generates a negative feedback loop that can limit damage from excessive inflammation.

Virus fighting just got a new boost

In a ground breaking study in the UK researchers have identified a previously unknown mechanism that allows the immune system to fight viruses even after they have infected cells. Until now it was believed that antibodies can act only before the virus enters the cells. The team now has found that antibodies that attached themselves to a virus were able to follow it into cells and help to destroy the virus before it started to reproduce. This could open up new avenues of therapy.

Research on AID enzyme could improve therapy for lymphoma, leukemia

A recent scientific discovery made by researchers at the Institut de recherches cliniques de Montr-al (IRCM) led by Dr. Javier Marcelo Di Noia, Director of the Mechanisms and Genetic Diversity research unit, was published online today by The Journal of Experimental Medicine. The team identified a mechanism regulating activation-induced deaminase (AID), which could be important for the therapy of some types of lymphoma and leukemia.

Idera presents data on TLR 3 agonist as vaccine adjuvants at Immunological Meeting

Idera Pharmaceuticals, Inc. today announced a presentation describing the chemistry and immunological activity of its proprietary Toll-Like Receptor (TLR) 3 agonist compounds and the use of these compounds as vaccine adjuvants in a preclinical model.

New shuttlte program helps probe spaceflight-induced immune-system impairment

When the space shuttle Discovery lifts off on its final flight Nov. 2, its six astronauts will be joined by 16 rodent passengers on a historic mission of their own. Riding in special self-contained modules that automatically supply them with food and water, the mice will be part of a long-term NASA effort aimed at understanding why spaceflight makes humans more vulnerable to infection by viruses and bacteria.

University of Maryland to establish major research enterprise for autoimmune diseases

With a new $45 million private gift from the family of a grateful patient, the University of Maryland School of Medicine is planning to establish the nation's only major research enterprise devoted to the study of autoimmune and inflammatory diseases such as celiac disease, multiple sclerosis, chronic obstructive pulmonary disease, asthma and Type 1 diabetes. The gift, from Indiana couple Ken and Shelia Cafferty, is the largest private donation in the history of the University System of Maryland.

Research on sheep population could help explain variation in vaccine protection

Strong immunity may play a key role in determining long life, but may do so at the expense of reduced fertility, a Princeton University study has concluded.

Antigenics third quarter net loss decreases from $10.8 million to $5.9 million

Antigenics Inc. reported today its results for the quarter ended September 30, 2010. The company incurred a net loss attributable to common stockholders of $5.9 million, or $0.06 per share, basic and diluted, for the third quarter of 2010, compared with a net loss attributable to common stockholders of $10.8 million, or $0.13 per share, basic and diluted, in the third quarter of 2009.

New findings suggest way to treat lung diseases

A new study of an exotic, infectious virus that has caused three recent outbreaks in the United States reveals clues to how the virus might damage lungs during infection. The findings also suggest possible new ways to treat lung diseases in humans.

Sex hormones behind increased risk of destructive periodontitis in men

Sex hormones may be the biological reason why men are at greater risk than women for destructive periodontitis, an infection of the gums, according to researchers at the University of Maryland Dental School.

Bivalent oral polio vaccine produces better immune response than more commonly used trivalent vaccine, study says

The bivalent oral polio vaccine (bOPV) was found to induce a significantly higher immune response than the existing trivalent oral polio vaccine (tOPV), according to a study published on Tuesday in the journal Lancet, Reuters reports.

Viral microRNA allows EBV to hide within cells and evade immune system

While most commonly associated with mononucleosis, Epstein-Barr virus (EBV) has been linked to many diseases that affect people long after the initial infection takes place, including some forms of cancer. In the current issue of the Journal of Biological Chemistry, scientists at The Wistar Institute describe how viral microRNA - small segments of RNA that suppress the effects of gene activity - allows EBV to hide within cells and evade the immune system.

FlexBone shows potential replacement for current bone transplantations

With a failure rate as high as 50 percent, bone tissue grafts pose a significant obstacle to orthopedic surgeons attempting to repair complex fractures or large areas of bone loss, such as those often caused by trauma and cancer. Current synthetic substitutes rarely possess the bone-like properties needed for successful grafting and are often difficult for surgeons to manipulate in the operating room. In response to these challenges, researchers at UMass Medical School have developed an easy-to-produce, inexpensive, synthetic bone material called FlexBone.
