An international team of researchers published a new study of the possible use of a biodetection technology developed by the Lawrence Livermore National Laboratory (LLNL) for rapid detection of emerging viral diseases by public health authorities. Livermore, California (PRWEB) July 15, 2014 A microbe detection array technology developed by Lawrence Livermore National Laboratory (LLNL) scientists could provide a new rapid method for public health authorities to conduct surveillance for...

Single Mutation Gives Virus A New Target

Brown University In a new study published online in the journal PLoS Pathogens, an international team of scientists showed that by swapping a single amino acid they could change the sugar to which the human BK polyomavirus will bind on the surface of cells. The BK polyomavirus lost the ability to bind its usual target sugar and instead “preferred” the same sugar as its cousin SV40 polyomavirus, which is active in monkeys. The researchers were working in cell cultures with safe...

For more than a decade the research group of Brown University Professor Walter Atwood has doggedly pursued the workings of the JC polyomavirus, which causes a disease called PML that fatally degrades the central nervous system of patients with weakened immune systems. In a study published online Oct. 2 in the Journal of Virology, his team describes how it gains entry into cells: It breaks in via certain receptors of the neurotransmitter serotonin called 5-HT2 receptors. Atwood, lead author...

Bird Virus Found In Dolphin

Brett Smith for redOrbit.com - Your Universe Online A group of marine biologists announced they have found a stranded dolphin on a San Diego beach that was apparently killed by a virus previously thought to have only a mild effect on mammals. The short-nosed dolphin was apparently killed by a polyomavirus, which is known to cause disease in birds. "It is therefore interesting that this particular polyomavirus appears to be what killed this dolphin," said Simon Anthony, a researcher at...

The JC polyomavirus is clearly opportunistic. It infects half the population but lethally destroys brain tissue only in immunocompromised patients – and it may be outright sneaky, too. Even as a new research paper allays fears that common mutant forms of the virus are the ones directly responsible for the disease's main attack, that same finding raises new questions about what the mutants are doing instead. Even if they are not the ones killing key brain cells, the mutants are up to...
