Promoter Structures and Differential Responses to Viral and Nonviral Inducers of Chicken Type I Interferon Genes

Abstract excerpt

Two serologically distinct type I interferons (IFNs), designated ChIFN1 and ChIFN2, are known in the chicken. ChIFN1 is encoded by a family of 10 or more genes, whereas ChIFN2 is encoded by a single gene. We show here that ChIFN1 and ChIFN2 transcripts are both strongly induced by Newcastle disease virus in primary chicken macrophages. By contrast, oral administration of the imidazoquinoline S-28463, which...
