CAMBRIDGE, Mass.--(BUSINESS WIRE)--Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), a leading RNAi therapeutics company, announced today the publication of new research findings in the journal Proceedings of the National Academy of Sciences (PNAS) by Alnylam scientists and collaborators from Mount Sinai School of Medicine. In the new study, Alnylam and Mount Sinai scientists discovered a novel class of virus-produced small non-coding RNAs, called small viral RNAs (svRNAs), which play a critical role in the replication of influenza A virus. Antagonism of these svRNAs resulted in decreased viral mRNA and blocked viral infectivity. These new findings provide further understanding of how influenza virus is able to infect cells, and identify new targets and strategies for anti-influenza virus-based therapies.
