Following RSV respiratory infection, an altered expression profile of certain cellular miRNAs, specifically immune‐associated miRNAs, occurs in order to inhibit viral replication and preserve the airway epithelial barrier; meanwhile, the virus induces or inhibits the expression of other miRNAs that favor viral replication. The RSV G protein enhances let‐7f, the RSV NS1/NS2 proteins decrease miR‐30b and enhance let‐7i, and RSV infection decrease miR‐221, which is an advantage for the virus
