Live vaccines more effective against horse herpes virus

..., home of the Kentucky Derby, a Cornell University virologist says his preliminary research indicates that vaccines containing weakened live viruses, called modified live vaccines (MLV), appear to be more effective in preventing horse herpes than other more widely used vaccines. "It's important that people kno...

Virologist finds contagious equine flu in dogs

A Cornell University virologist has isolated a highly contagious equine flu virus that is spreading a sometimes-fatal respiratory flu among dogs, and is responsible for a major dog-flu outbreak in New York state. There is no evidence that the virus could infect people. According t...

Other key co-authors from the Hamilton, MT, RML laboratory include Richard Race, D.V.M., and Gerald Baron, Ph.D. Their collaborators included Michael Oldstone, M.D., and Matthew Trifilo, Ph.D., of The Scrip...

Federal grant funds research on novel HIV therapy

...s four separate projects. Projects 1 and 2, led by virologist Wen-Zhe Ho, M.D., of Children's Hospital, and Dr. Douglas, respectively, aim to better understand the underlying mechanisms behind anti-HIV activity of NK-1R antagonists. The basic science research will particularly examine how these agents affect HI...

Cell barrier shows why bird flu not so easily spread among humans

...earch group led by University of Wisconsin-Madison virologist Yoshihiro Kawaoka, describes experiments using tissue from humans that showed that only cells deep within the respiratory system have the surface molecule or receptor that is the key that permits the avian flu virus to enter a cell. Flu viruses, lik...

Scientists identify molecular structure of key viral protein

...able to the whole family of paramyxoviruses," said virologist Robert A. Lamb, John Evans Professor of Biochemistry, Molecular Biology and Cell Biology and co-leader of the study. "The family includes viruses that cause measles, mumps, bronchitis, pneumonia, canine distemper, croup and Newcastle disease, which k...

Research holds promise for herpes vaccine

...hed earlier this year in the Virology Journal, MSU virologist William Halford showed that mice vaccinated with a live, genetically-modified herpes simplex virus type 1 (HSV-1) showed no signs of disease 30 days after being exposed to a particularly lethal "wild-type" strain of the virus. In contrast, a second...

Scientists find mutations that let bird flu adapt to humans

...waoka, the senior author of the Nature paper and a virologist at the University of Wisconsin-Madison School of Veterinary Medicine. "Both changes are needed for the H5N1 virus to recognize human receptors." The new report provides a molecular blueprint for the genetic changes required to transform a virus th...

Researchers discover that sheep need retroviruses for reproduction

...g their evolution," said. Dr. Massimo Palmarini, a virologist at The University of Glasgow Veterinary School. "This infection was beneficial to the host and was then positively selected for during evolution. In other words, animals with enJSRVs were better equipped than those without. Therefore, enJSRVs became ...

Mayo researchers discover HIV dependence on a human protein

...estion," says Eric Poeschla, M.D., the Mayo Clinic virologist who led the research. "It's critical to understand this better because permanently integrated viruses in long-lived cells prevent elimination of HIV. In the future, it will be of interest to examine whether HIV's dependence on p75 can be exploited th...

Study uncovers a lethal secret of 1918 influenza virus

...ure, a team led by University of Wisconsin-Madison virologist Yoshihiro Kawaoka reveals how the 1918 virus - modern history's most savage influenza strain - unleashes an immune response that destroys the lungs in a matter of days, leading to death. The finding is important because it provides insight into ho...

How 'memory' T cells curb the spread of viruses throughout the body

...eases has been debated. The new work by Fox Chase virologist Luis J. Sigal, D.V.M., Ph.D., and his Fox Chase colleagues in the virology and pathology programs, provides the basis whereby memory CD8 T cells do, in fact, prevent viral diseases. CD8 T cells normally reside in lymphoid organs such as the lymph n...
