Austin American-Statesman, Aug. 26, 2008 This article is about separate studies at UT Austin and UTMB in the fight against influenza.  UTMB's Dr. Christine Turley, who is heading up a study for a universal influenza A vaccine, comments on the UT Austin study in which researchers have discovered a "tricky protein" that attaches itself to a protein in human cells and prevents the immune system from mounting a defense against the virus. "This is a great step forward," Turley said. "It's an early stage discovery ... but the more we understand about the structure of that (virus) and the interactions of the proteins at the molecular level, the more we'll be able to develop good drugs."  Turley said the vaccine she is testing has shown promise in clinical trials. Turley is expected to present early test results Oct. 25-28 at a joint meeting of the Infectious Diseases Society of America and the Interscience Conference on Antimicrobial Agents and Chemotherapy in Washington.
