Species Specific

The picornavirus foot-and-mouth disease virus (FMDV) is responsible for one of the most significant diseases of livestock, leading to large economic losses due to reduced productivity and trade embargoes for areas not certified as disease-free. The picornavirus non-structural protein 3A is involved in replication of the viral RNA genome and is implicated in host tropism of several picornaviruses. Deletions in the C-terminus of 3A have been observed in FMDV outbreaks specific for swine and such viruses are non-pathogenic in cattle. The mechanism for species specific attenuation of FMDV is unknown. We have shown that FMDV containing a C-terminal deletion in 3A is attenuated in bovine cell culture and that the attenuated phenotype can be reversed by the JAK1/2 inhibitor Ruxolitinib (Rux), identifying a role for the induction of interferon stimulated genes (ISGs) in the restricted bovine tropism of the 3A-deleted virus.

Early Origin

Abstract In this study, we compiled 84-year worth (1934–2017) of genomic and epidemiological data of foot-and-mouth disease virus (FMDV), and performed comprehensive analyses to determine its early origin and transmission route. We found that recombination is a key feature of FMDV, and that the genomic regions coding for structural and non-structural proteins have markedly different evolutionary histories, and evolve at different rates. Despite all of these differences, analyses of both structural and non-structural protein coding regions consistently suggested that the most recent common ancestor of FMDV could be dated back to the Middle Age, ~ 200 to 300 years earlier than previously thought. The ancestors of the Euro-Asiatic and SAT strains could be dated back to the mid-seventeenth century, and to the mid-fifteenth to mid-sixteenth century, respectively. Our results implicated Mediterranean counties as an early geographical origin of FMDV before spreading to Europe and subsequently to Asia and South America.

Fmdv Replication

Foot-and-mouth disease virus (FMDV) is the etiological agent of FMD, which affects domestic and wild cloven-hoofed animals. The structural protein VP1 plays an important role in FMDV pathogenesis. However, the interacting partners of VP1 in host cells and the effects of these interactions in FMDV replication remain incompletely elucidated. Here, we identified a porcine cell protein, serine/threonine kinase 3 (STK3), which interacts with FMDV VP1 using the yeast two-hybrid system. The VP1-STK3 interaction was further confirmed by coimmunoprecipitation experiments in human embryonic kidney 293T and porcine kidney 15 (PK-15) cells. The carboxyl-terminal region (amino acids 180–214) of VP1 was essential for its interaction with STK3. The effects of overexpression and underexpressing of STK3 in PK-15 cells were assessed, and the results indicated that STK3 significantly inhibited FMDV replication. Our data expand the role of STK3 during viral infection, provide new information regarding the host cell kinases that are involved in viral replication, and identify potential targets for future antiviral strategies.
