Sirna Compositions And Methods For Potently Inhibiting Viral Infection

总结

No Antiviral Regimen Has Been Consistently Successful In Treating H5n1 Virus Infection. We Demonstrate That A Group Of Highly Effective Sirnas Targeting Different H5n1 Viral Genes Shares A Unique Motif, Ggagu/Acucc. We Further Demonstrate That The Effectiveness Of Sirnas Containing This Motif Is Not Sequence Specific. The Results Suggested That The Structure Of The Unique Motif Is Critical In Determining The Potency Of Sirna-Mediated Protective Effects Against Viral Infection And This Potent In Vivo Protection Is Associated With Early Productions Of [Beta]-Defensin And Il-6 Induced By The Motif. Provided Are Methods And Prophylactic And Therapeutic Agents Useful Against Other Viral Infections In Addition To The H5n1 Influenza Virus.

Title: siRNA compositions and methods for potently inhibiting viral infection
Usefulness: siRNA compositions and methods for potently inhibiting viral infection
Summary: For preparing an agent for stimulating interleukin-6 (IL-6) production or for stimulating β -defensin production in a subject; for screening of potential antiviral agents; and as antiviral agents (all claimed), for prophylaxis or treatment of viral infection, preferably by H5N1 influenza virus.
Novelty: New small interfering RNAs useful for prophylaxis or treatment of influenza A virus infection, comprise pentanucleotide motif or reverse motif having specific nucleotide sequence
