According to a preprint abstract from biorxiv.org, researchers have found that the stearoyl coenzyme A desaturase 1 (SCD1) enzyme plays a role in regulating the replication of the foot-and-mouth disease virus (FMDV) by modulating host cell lipid metabolism and the formation of replication complexes. The study showed that overexpression of SCD1 or the addition of oleic acid (OA), a product of SCD1 activity, increased FMDV replication in certain cells. Inhibition of SCD1 activity also suppressed replication of other positive-sense RNA viruses. These findings suggest that SCD1 could be a potential target for developing drugs against positive-sense RNA virus infections.

These findings suggest that interactions with capsid precursors control the fate of viral genomes, either leading to packaging or serving as templates for replication and protein translation. However, it is important to note that this preprint has not yet undergone peer review. [Extracted from the article]

According to a preprint abstract from biorxiv.org, the 5' untranslated region (UTR) of the foot-and-mouth disease virus (FMDV) contains a highly conserved and essential structure called the short (S) fragment. The precise function of this structure is unclear, but it is believed to play a role in viral replication. Researchers used selective 2' hydroxyl acetylation analyzed by primer extension (SHAPE) to determine aspects of the structure and found that deletions in the stem loop of the S fragment affected genome replication in a size-dependent and host cell-dependent manner. Additionally, during the passage of viruses with the largest tolerated deletion, an additional mutation was selected in the viral RNA-dependent RNA polymerase, suggesting an interaction between the S fragment and the polymerase in the formation of the FMDV replication complex. This research has not yet undergone peer review. [Extracted from the article]

After one or three doses of a vaccine derived from a Sudanese SAT2 virus of topotype VII originated in 2010, heterologous neutralizing antibody titres with Sudanese SAT2 viruses in 2008 were <= 1.2 log 10, not consistent with likely protection. When r1 values between the vaccine virus and the SAT2 viruses isolated in 2008, whilst topotype XIII was circulating, were derived, values (approximate to 0.00) suggested similarly poor antigenic relationship and unlikely cross protection.
