Polynucleotides for reducing respiratory syncytial virus gene expression

摘要

This invention pertains to polynucleotides, such as small interfering RNA (siRNA), useful for reducing the expression of respiratory syncytial virus (RSV) genes within a subject; and methods for treating a patient suffering from, or at risk of developing, an RSV infection by administering such polynucleotides to the subject.

主权项

1. A method for reducing the expression of a respiratory syncytial virus (RSV) gene and RSV viral titer in a human subject, comprising administering a vector to airway cells in the subject, wherein the subject does not have an RSV infection at the time the vector is administered, wherein the vector comprises a nucleic acid sequence encoding a short interfering RNA (siRNA) targeted to a target nucleic acid sequence within the RSV NS1 gene or RSV NS1 transcript, and wherein the vector is administered in an effective amount to reduce expression of the RSV NS1 gene or NS1 transcript in the airway cells and reduce RSV titer in the subject.
