Experimental vaccine against human norovirus generates strong, safe immune response in mice

Scientists have shown that an experimental vaccine against the human norovirus - the bug behind about 90 percent of highly contagious nonbacterial illnesses that cause diarrhea and vomiting - can generate a strong immune response in mice without appearing to cause the animals any harm.

Scientists determine protein structure that delivers genetic material of HIV to human cells

A team of scientists at The Scripps Research Institute and the University of Virginia has determined the structure of the protein package that delivers the genetic material of the human immunodeficiency virus to human cells.

Molecular interaction between structural HCV protein and protein critical to viral replication identified

Scientists from the Florida campus of The Scripps Research Institute have identified a molecular interaction between a structural hepatitis C virus protein (HCV) and a protein critical to viral replication. This new finding strongly suggests a novel method of inhibiting the production of the virus and a potential new therapeutic target for hepatitis C drug development.

Scientists find potential Achilles Heel in JC polyomavirus

The JC polyomavirus doesn't strike very often, but it's a mean bug that preys on people with weakened immune systems, including people with AIDS, and almost always kills them. Now an international team of scientists at Brown University, the University of T-bingen in Germany, and Imperial College in London has found a potential Achilles Heel and painted a target on it: The virus must bind to a very specific sugar molecule dangling from the side of the brain cells it attacks.

LigoCyte to enroll 98 subjects in first clinical trial for bivalent IM norovirus vaccine

LigoCyte Pharmaceuticals, Inc., a private, clinical-stage biopharmaceuticals company focused on the development of innovative vaccine products, announced today that it has initiated the first clinical trial for its bivalent intramuscular (IM) norovirus vaccine candidate, marking the fourth human clinical trial in the Company's norovirus virus-like particle (VLP) vaccine program.

Scientists discover sensor in dendritic cells that recognizes HIV

Dendritic cells are the grand sentinels of the immune system, standing guard 24/7 to detect foreign invaders such as viruses and bacteria, and bring news of the invasion to other immune cells to marshal an attack. These sentinels, however, nearly always fail to respond adequately to HIV, the virus causing AIDS. Now a team of scientists at NYU Langone Medical Center has discovered a sensor in dendritic cells that recognizes HIV, spurring a more potent immune response by the sentinels to the virus.

Trigger that induces B cells to produce early, effective antibody response discovered

Researchers at National Jewish Health have discovered a trigger that induces B cells to produce effective and long-lived antibodies early in the immune response. They found that a molecule that binds toll-like receptors doubles the early antibody response to an antigen, and shifts it to a more effective, IgG form.

New research may help advance treatment strategies for common liver disease

A research article published in the journal PloS Pathogens could lead to improvements in the production of vaccines for hepatitis A, the most widespread viral disease in the world.

Third human clinical trial of LigoCyte's norovirus vaccine started

LigoCyte Pharmaceuticals, Inc. announced today that it has initiated its third human clinical trial of its norovirus vaccine. The Phase I/II study will assess safety and immunogenicity associated with LigoCyte's investigational, nasally-delivered, dry powder vaccine in healthy adults. The study will also assess potential protection against clinical symptoms of norovirus infection by including a live virus challenge of subjects that have received either the vaccine or placebo.

Structure of the HIV protein shell revealed

New research by scientists at The Scripps Research Institute and other institutions provides a close-up look at the cone-shaped shell that is the hallmark of human immunodeficiency virus (HIV), revealing how it is held together - and possible ways to break it apart.

Scientists determine key structural features of mimivirus

The mimivirus is the largest virus known to scientists, about half of a micrometre (0.0005 millimeter) in diameter.

Scientists discover key molecules that inhibit viral production

The research, led by Professor Donny Strosberg of Scripps Florida, was published on March 4, 2009, in the Journal of General Virology's advance, online edition, Papers in Press.

A potential marker of increased histological activity in hepatitis C virus infection

Early, vigorous and sustained lymphocyte proliferative responses specific to hepatitis C virus (HCV) have been regarded as pivotal for viral clearance.

How DNA is packed

The life cycles of many viruses include a self-assembly stage in which a powerful molecular motor must pack the DNA genome into the virus's preformed shell (the capsid). How it manages this intricate feat has been subject to debate, but we know that the DNA passes into the capsid shell through a channel formed by a structure called the connector. Scientists have speculated that rotation of the connector complex might feed the DNA into the capsid as it turns.
