In-shell vaccine for chick disease

Infectious bronchitis virus causes devastating losses to the poultry industry but scientists are now developing a new way to vaccinate chicks against the disease -- one that can be delivered while they are still in their egg. Researchers have used a "reverse genetic" system to produce a new vaccine strain which is safe to deliver to chicks while they are still in the egg, making it more effective than current vaccines.

   Diane Griffin, M.D., Ph.D., of Johns Hopkins University Bloomberg School of Public Health will be presenting findings on Thursday, May 31 at the 10th Annual American Society of Gene Therapy meeting in Seattle showing that an experimental measles DNA vaccine showed promising results in infant monkeys and achieved "sterilizing immunity," or near-complete eradication of disease, in juvenile monkeys. The studies were conducted under a grant from the Bill and Melinda Gates Foundation.

   An international team of experts has published the first comprehensive review of evidence on pneumococcal conjugate vaccination for children with HIV infection. Now available in the online edition of the journal Lancet Infectious Diseases, the review shows that HIV increases the risk of pneumococcal infection by up to 40 fold, that the disease is usually due to serotypes in the PCV, and that the vaccine can protect HIV-infected infants.

6. Unlocking proteins from their cellular shell
   08-02-2007 · EurekAlert!
   Applying physical stress to cells, researchers at the University of Pennsylvania have demonstrated that everyday forces can alter the structure of proteins tucked within cells, unfold them and expose new targets in the fight against disease.The findings for both simple red blood cells and more versatile stem cells show that hidden and folded parts of proteins can be exposed by physical strain. From there, proteins can be labeled and mapped, increasing the understanding of cellular behavior and unlocking novel targetable sites for drugs.
