Characterization of an essential RNA secondary structure in the 3' untranslated region of the murine coronavirus genome.

abstract：UNLABELLED:Type I IFN signaling, which is initiated through activation of the alpha interferon receptor (IFNAR), regulates the expression of proteins that are crucial contributors to immune responses. Paramyxoviruses, including human metapneumovirus (HMPV), have evolved mechanisms to inhibit IFNAR signaling, but the sp...
