The small RNA component was originally identified through a process called deep sequencing. This revolutionary new technique allows scientists to obtain millions of small RNAs from cells in a completely unbiased fashion. The technique was applied to lung cells infected with influenza A virus and ultimately led to the discovery of the first small RNA component ever identified from this family of viruses.

"Questions remain about exactly how the svRNAs function," said Dr. tenOever. "We're also hoping to engineer a means of delivering RNA-based antagonists into the body's system as a means of inhibiting svRNA function. We're still a few years off from solving the entire puzzle. However, by finding this one piece, a universal treatment for all strains of influenza is within reach of becoming a reality."
