Research summary:

Foot-and-mouth disease virus (FMDV) is one of the major concerns for animal health. It is also an interesting model system for understanding the interactions of a highly variable virus and its natural hosts and the implications of these interactions on disease control. We are working in the development of new FMDV peptide marker vaccines that can induce protective humoral and cellular immune responses, using pig and cattle, important domestics hosts, as animal models. We have also analyzed the functional role of FMDV proteins on the viral particle stability and internalization, the replication cycle and the mechanisms mediating the pathogenesis of FMDV and other related viruses causing vesicular diseases, such as swine vesicular disease virus (SVDV), and vesicular stomatitis virus (VSV). Special attention has been paid to the functional implications of nonstructural proteins in virus virulence and host range. The role of different cellular lipids in the multiplication of these and other viruses such as West Nile virus (WNV), responsible for an important zoonosis, have also been addressed. As part of these studies, we have continued collaborating in the characterization of the inhibitory effect of valproic acid and other antiviral compounds targeting cellular metabolism such as lauryl gallate on the multiplication of FMDV and of other enveloped viruses, like African swine fever virus (ASFV) and type I herpesvirus.

In a second line of research, Margarita Sáiz undertakes the analysis of the interplay between FMDV and the innate immunity system. With the aim of unveiling the molecular mechanisms exerted by FMDV for immune evasion, the role of the two virally-encoded proteases is being studied. We have shown that the FMDV Leader protease targets innate immune sensor LGP2 for cleavage, resulting in lower levels of IFN-β and antiviral activity. The interference of the proteases with different signaling routes triggered by viral sensors and their interaction with a variety of immune effectors as potential targets for viral antagonism are being analyzed.

On the other hand, the biotherapeutic applications of synthetic non-coding RNAs derived from the viral genome, and known to elicit a broad spectrum antiviral activity, is being explored. We have shown that RNA delivery enhanced the specific B- and T-cell mediated immune responses elicited by a conventional FMD vaccine, increasing the rate of protection against viral challenge. The activity of these molecules in livestock species is being analyzed to assess their biotechnological potential for the development of new antiviral molecules and vaccine adjuvants.
