SAN DIEGO, April 15 /PRNewswire/ -- NexBio, Inc. announced today that it has completed the formation of a new Clinical Advisory Board (CAB) to complement its existing group of Senior Advisers. NexBio recently completed a First-In-Man clinical trial of DAS181 (Fludase(R)), an investigational drug candidate for influenza. The new CAB will guide NexBio throughout the clinical development of this novel medicine, helping the company to conduct advanced product development to address the...

U.S. scientists say they've found how the avian influenza virus "hides" from the body's immune system, preventing an antiviral response from infected cells. Baylor College of Medicine researchers said they discovered a protein found in the virulent avian flu virus strain called H5N1 forms tiny tubules in which it "hides" the pieces of double-stranded RNA formed during viral infection. Professor B.V. Venkataram Prasad and Zachary Bornholdt, now with the Scripps Research Institute,...

Scientists and researchers have taken a big step closer to a cure for the most common strain of avian influenza, or "bird flu," the potential pandemic that has claimed more than 200 lives and infected nearly 400 people in 14 countries since it was identified in 2003. Researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory, in conjunction with scientists from China and Singapore, have crystallized and characterized the structure of one of the most important protein...

As they design new drugs to fight off influenza, scientists may not need to attack the virus directly. Instead, they may be able to stave off infection by targeting one of more than 100 proteins inside host cells on which the virus depends. These potential drug targets are the result of a study in which scientists, led by Howard Hughes Medical Institute investigator Paul Ahlquist and colleague Yoshihiro Kawaoka at the University of Wisconsin-Madison, tested the ability of a modified influenza...

Researchers have found nearly 100 genes that the H5N1 bird flu virus needs in a host to be able to duplicate.  The finding will help researchers better understand how to keep the virus from reproducing. In the newest edition of Nature Magazine, the scientists wrote, "All viruses rely on host cell proteins and their associated mechanisms to complete the viral life cycle. Identifying the host molecules that participate in each step of virus replication could provide valuable new targets...

MILWAUKEE, Wis. _ A team from the University of Wisconsin-Madison is one step ahead of a quickly evolving influenza virus that's been threatening the planet with pandemic disease for the past five years. The team, under Yoshihiro Kawaoka, is leading the charge to find new drugs and weapons to fight a virus that has evolved to resist the only drugs known to beat it. Using a novel approach to screen for genes that aid and abet flu viruses, Kawaoka's team has opened the door for the rapid...

Flu viruses must be able to break a very specific code before it can enter and infect human respiratory cells, U.S. researchers said on Sunday, presenting a new understanding of how influenza works.This discovery may be able to offer scientists a better way to monitor changes in the H5N1 bird flu virus that could possibly trigger a deadly pandemic in humans. It may also lead to better ways to fight it as well. Scientists found that a flu virus must be able to attach itself to an...

By Patricia Reaney LONDON (Reuters) - Scientists have solved the genetic puzzle of how influenza A viruses -- including the H5N1 bird flu -- replicate inside cells, which could help to speed up the development of new drugs to avert a pandemic. As governments bolster efforts to halt the spread of avian flu which has killed 83 people since 2003, an international team of researchers has discovered that the flu virus infects cells by organizing its genetic material in a set of eight segments....

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Genetic tests of samples taken from Turkish victims of the bird flu virus show it has made a small change but probably not enough to make it more dangerous yet, researchers said on Thursday. The mutation is one that would be expected in a highly changeable virus, the experts said, and is one that would be predicted to eventually allow it to cause a pandemic. H5N1 avian influenza has caused a burst of human...
