HOUSTON, Nov. 6 (UPI) -- 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.
