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).

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.

Hep C treatment pegylated interferon reduces the virus but liver damage continues

Treating patients who have chronic hepatitis C and advanced liver disease with long-term pegylated interferon significantly decreased their liver enzymes, viral levels and liver inflammation, but the treatment did not slow or prevent the progression of serious liver disease, a study finds.

Researchers study virus with unusual properties

A team of researchers from Penn State University and the University of Chicago has uncovered clues that may explain how and why a particular virus, called N4, injects an unusual substance -- an RNA polymerase protein -- into an E. coli bacterial cell.

Potential new therapy for hepatitis C treatment

Combination therapies similar to those used for HIV patients may be the best way of treating hepatitis C virus (HCV), say researchers from the University of Leeds.

Biologists spy close-up view of poliovirus linked to host cell receptor

Researchers from Purdue and Stony Brook universities have determined the precise atomic-scale structure of the poliovirus attached to key receptor molecules in human host cells and also have taken a vital snapshot of processes leading to infection.

Gene therapy used to fight AIDS

The apparent success of a case in which German doctors cured a man of AIDS using a bone marrow transplant comes as no surprise to Gerhard Bauer, a UC Davis stem cell researcher.

Effects of stem cell source and patient age on stem cell transplantation outcomes

Two studies examining the effects of stem cell source and patient age on stem cell transplantation outcomes were explored at a press conference on Sunday, December 7 during the 50th Annual Meeting of the American Society of Hematology in San Francisco, CA.

Scientists pinpoint immune-system targets in complex pathogens

Our immune cells have an amazingly intricate recognition system to detect invading pathogens. Often, the intricacies have overwhelmed scientists who want to know exactly what gives an alarm signal to T cells, a class of white blood cells that recognizes invaders.

Well-armed immune cells help long-term non-progressors contain HIV

To help develop an effective HIV vaccine, researchers are trying to better understand how the immune systems of a small minority of HIV-infected people known as long-term non-progressors (LTNPs) contain the virus naturally.

Breakthrough in understanding the phenomenon of nucleolar dominance

Since the machinery involved in nucleolar dominance is some of the same machinery that can go haywire in diseases such as cancer, Pikaard and his collaborators' research may have important implications for applied medical research.

Interferon as long-term treatment for hepatitis C not effective

Use of the drug interferon as a long-term maintenance strategy to slow the progression of liver disease associated with the hepatitis C virus is ineffective, UT Southwestern Medical Center researchers and their colleagues from nine other institutions have found in a multicenter study.
