Researchers develop universal influenza vaccine for animals

A University of Maryland-led science team has developed a universal influenza vaccine for animals that may help prevent or delay another human flu pandemic.

Research suggests that immunity is stronger at night

The immune system's battle against invading bacteria reaches its peak activity at night and is lowest during the day.

Possible new therapeutic target for pancreatic cancer

A possible new therapeutic target for pancreatic cancer, the most lethal form of human cancer, has been identified in the proteins whose DNA recipe comes from gene, "Seven-In-Absentia," according to researchers at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Researchers identify how key mutations occur in human lymphomas

Researchers at the Keck School of Medicine of the University of Southern California (USC) have explained how certain key mutations occur in human lymphomas - a process that has, until now, remained a mystery.

Humble toothbrush helps stop ventilator-associated pneumonia

Hospital-borne infections are a serious risk of a long-term hospital stay, and ventilator-associated pneumonia (VAP), a lung infection that develops in about 15% of all people who are ventilated, is among the most dangerous.

Novavax announces positive results in trial of seasonal influenza VLP (trivalent) vaccine candidate

Novavax, Inc. has announced favorable results from a Phase IIa human clinical trial of its seasonal influenza VLP (trivalent) vaccine candidate.

Enzyme that mutates antibodies also targets cancer-causing gene

The human immune system is in a perpetual state of self-experimentation. It expertly mutates and shuffles the DNA of its own cells to evolve new defenses against the vast array of microbes that try to invade our bodies.

Scientists show that HIV's evolution in the body does not occur at a constant rate

HIV is so deadly largely because it evolves so rapidly. With a single virus as the origin of an infection, most patients will quickly come to harbor thousands of different versions of HIV, all a little bit different and all competing with one another to most efficiently infect that person's cells. Its rapid and unique evolution in every patient is what allows HIV to evade the body's defenses and gives the virus great skill at developing resistance to a pantheon of antiviral drugs.

Enzyme that mutates antibodies also targets a cancer-causing oncogene

Rockefeller University scientists have discovered that the same enzyme that enables the immune system's defensive creativity is also responsible for a particular genetic malfunction - a translocation of one piece of DNA to the wrong chromosome - that causes Burkitt's lymphoma.

Vaxfectin-formulated H5N1 pandemic influenza achieves T-cell responses and cross-clade reactivity in humans

Vical Incorporated has announced that the company's Vaxfectin-formulated H5N1 pandemic influenza DNA vaccines induced T-cell responses against a matching strain of influenza virus and demonstrated cross-clade antibody responses against a different strain in a Phase 1 clinical trial.

Mathematical models of adaptive immunity

More than five million people die every year from infectious diseases, despite the availability of numerous antibiotics and vaccines. The discovery of penicillin to treat bacterial infections, along with the development of vaccines for previously incurable virus diseases such as polio and smallpox, achieved great reductions in mortality during the mid-20th century.

Genetic links found between type 1 diabetes and celiac disease

Type 1 (juvenile) diabetes and celiac disease appear to share a common genetic origin, scientists at the University of Cambridge and Barts and The London School of Medicine and Dentistry, have confirmed.

RNA interference can facilitate vaccine development

Pharmaceutical companies and universities are racing to develop drugs that use the gene silencing mechanism known as RNA interference to treat a host of diseases.

Scans show immune cells intercepting parasites

Researchers may have identified one of the body's earliest responses to a group of parasites that causes illness in developing nations.

Blocking immune receptor molecule improves response to HIV-like virus, prolongs survival in monkeys

By blocking PD-1 (programmed death-1), an immune receptor molecule known to inhibit the immune response to chronic viral infections, scientists have safely and significantly reduced the plasma viral load and also prolonged survival of rhesus macaque monkeys severely infected with simian immunodeficiency virus (SIV), the nonhuman primate version of human immunodeficiency virus (HIV).

UK kidney cancer patients face toxic, out-dated treatments with little hope of change

Leading oncologist Professor Tim Eisen has expressed concerns that patients with advanced kidney cancer could be condemned to toxic, barely effective, 20 year-old treatments because the National Institute for Health and Clinical Excellence (NICE) is likely to rule out using all four of the new treatments it has assessed.

DNA vaccine for SARS achieves neutralizing responses in first U.S. human trial

Vical Incorporated (NASDAQ:VICL) today announced that results from a Phase I clinical trial of a DNA vaccine for severe acute respiratory syndrome (SARS), conducted by the National Institutes of Health (NIH) and published in the November 25 issue of Vaccine(1), demonstrated that the vaccine was well-tolerated, and induced neutralizing antibody responses in 80% of the vaccinees and T-cell immune responses in all vaccinees.
