As a result, mice become more susceptible to viral infection. Siramesine<\/a> Although IRF3 has been reported to preferentially activate IFN-b over IFN-a genes, IRF7 is believed to efficiently activate both IFN-a and IFN-b. The human IFN-b promoter region contains four positive regulatory domains that serve as binding sites for IRFs. In the human IFN-a promoter region there may be two or three PRD modules depending on the IFN-a subtype. Due to the importance of IRF7 in the innate immune response, it is an active target for viruses to evade the host immune response. A role for IRF7 in immunosurveillance has also been identified in breast cancer. Using the Australian black flying fox as a model species we have begun to explore the role of the IFN system in the control of viral replication in bats. We have demonstrated that TLRs, RIG-Ilike receptors, and some IFN stimulated genes appear to be conserved in sequence compared to other mammals. BAY 1000394<\/a> However, bats appear to have relatively higher expression of type III IFN and wider distribution of type III IFN receptors consistent with a role for type III IFNs in antiviral immunity. Bat genome analysis has also provided evidence for positive selection of genes within the IFN pathway, including TLR7, c-Rel, TBK-1, IFN-c, ISG15 and RIG-I. These changes may have occurred in response to the co-evolution of bats with viruses and may have consequences for the clearance of viral infections and the ability of bats to coexist with viruses. Due to the central role of IRF7 in the regulation of the IFN response, we performed sequence and functional analysis of P. alecto IRF7. Our results provide the first description of IRF7 in any species of bat and evidence for conserved IRF7 functional activity despite variation at the sequence level in the bat IRF7 gene. Primers listed in Table 1 were designed based on the P. alecto genomic sequences and used in RT-PCR to amplify IRF7, IRF3 and MyD88 from RNA extracted from freshly isolated bat splenocytes. To construct expression plasmids, PCR products corresponding to full-length IRF3 and IRF7 were ligated directly to Vivid Colors pcDNA 6.2\/EmGFP TOPO vector with an N-terminal GFP tag.<\/p>\n","protected":false},"excerpt":{"rendered":"
