Doctoral thesis on Classical Swine Fever

On January 25, 2012, Joan Tarradas Font (PhD student of the CReSA) will defend his doctoral thesis entitled “Studies on immunopathogenesis of classical swine fever virus for developing of new vaccination methods”, directed by Dr Llilianne Ganges.

The event will be held on January 25, 2012 (12:00h), in the Sala d’Actes of the Facultat de Veterinària (Universitat Autònoma de Barcelona).

The work of this thesis helped to clarify the role of cellular responses associated with IFN-gamma pathway in protection against classical swine fever virus (CSFV). On the other hand, it demonstrated the involvement of alpha IFN in the development of the acute form of the disease. High levels of alpha IFN detected in the sera of infected animals may be related to the immunosuppression, survival of virus in the host and, at the same time, can be considered as a marker of viral replication.

We characterized the immunomodulatory capacity of the swine chemokine CCL20 on DNA vaccination against CSFV. The co-injection of plasmid expressing this chemokine with the E2 protein can induce a sterilizing protection against the virus.

Finally, this thesis showed that the strategy of vaccination with dendrimeric peptide can be used as a DIVA (Differentiation of Infected and Vaccinated Animals) vaccine candidate against the virus. In addition, it has been shown that dendrimers are an effective tool for the characterization of new B and T CSFV epitopes in vivo.
