چکیده
Foot-and-mouth disease virus (FMDV) is the most contagious pathogen of cloven-hoofed animals. Previous studies have demonstrated that type I interferons [alpha/beta interferons (IFN/ s)] can suppress FMDV replication and spread. Conversely, FMDV can also inhibit IFNexpression in infected cells by

The leader proteinase of foot-and-mouth disease virus inhibits the induction of beta interferon mRNA and blocks the host innate immune response.
We have previously shown that the leader proteinase (L(pro)) of foot-and-mouth disease virus (FMDV) blocks cap-dependent mRNA translation and that a genetically engineered FMDV lacking the leader proteinase coding region (A12-LLV2) is attenuated in cell culture and susceptible animals. The attenuated phenotype apparently is a consequence of the inability of A12-LLV2 to block the expression of t...
متن کاملChanges in some pro-and anti-inflammatory cytokines produced by bovine peripheral blood mononuclear cells following foot and mouth disease vaccination
Interleukin (IL)-17 is exclusively produced by CD4 helper T-cells upon activation. It most often acts as a pro-inflammatory cytokine, which stimulates the release of pro-inflammatory cytokines IL-6, IL-8, TNF-α, and granulocyte-macrophage colony-stimulating factor (GM-CSF). In this study, we studied the in-vitro IL-17 response to specific antigens and a variety of mitogens and compared the IL-1...
متن کاملNovel viral disease control strategy: adenovirus expressing alpha interferon rapidly protects swine from foot-and-mouth disease.
We have previously shown that replication of foot-and-mouth disease virus (FMDV) is highly sensitive to alpha/beta interferon (IFN-alpha/beta). In the present study, we constructed recombinant, replication-defective human adenovirus type 5 vectors containing either porcine IFN-alpha or IFN-beta (Ad5-pIFNalpha or Ad5-pIFNbeta). We demonstrated that cells infected with these viruses express high ...
متن کاملComparative transcriptome analyses indicate enhanced cellular protection against FMDV in PK15 cells pretreated with IFN-γ.
Interferon gamma (IFN-γ) can induce a host antiviral response to foot and mouth disease virus (FMDV) in vivo and in vitro. To elucidate the mechanism of IFN-γ anti FMDV infection in host cells, high-throughput RNA sequencing was analyzed for systemic changes in gene expression profiles in PK15 cells infected by FMDV with or without IFN-γ pretreatment. More than 25 million reads, covering 1.2-1....
متن کاملRNA structural domains in noncoding regions of the foot-and-mouth disease virus genome trigger innate immunity in porcine cells and mice.
The induction of type I interferons (alpha/beta interferon [IFN-α/β]) in response to viral infection is a crucial step leading to the antiviral state in the host. Viruses produce double-stranded RNA (dsDNA) during their replication cycle that is sensed as nonself by host cells through different receptors. A signaling cascade then is activated to block viral replication and spread. Foot-and-mout...
