Lumazine synthase from Brucella spp. (BLS) is a highly immunogenic decameric protein. It has been previously described as a carrier of peptides or proteins to increase their immunogenicity in different animal species, but its activity has never been evaluated in chickens. In this work, the use of BLS to improve the antibody response against bovine rotavirus (BRV) VP8d protein in laying hens was assessed. VP8d is the inner domain of the VP8 spike protein which preserves the sialic acid binding activity and the neutralizing epitopes present in the viral protein. Hens were immunized three times with 2 μg of VP8d alone or fused to BLS. Hens inoculated with BLSVP8d developed higher antibody titers (evaluated by ELISA and viral neutralization test) than hens immunized either with VP8d alone or the mixture of VP8d and BLS. Furthermore, IgY antibodies against BLSVP8d were able to fully protect mice against challenge with virulent BRV in a dose-depent-manner. Overall, these results demonstrate that BLS is a potent immonumodulator that enhances the antibody response in hens, thus increasing the concentration of specific IgY in the egg yolk, one of the main issues to be adressed in order to improve the use of the IgY technology.

Despite advances in therapy, hepatitis C virus(HCV) infection remains an important global health issue. It is estimated that a significant part of the world population is chronically infected with the virus, and many of those affected may develop cirrhosis or liver cancer. The virus shows considerable variability, a characteristic that directly interferes with disease treatment. The response to treatment varies according to HCV genotype and subtype. The continuous generation of variants(quasispecies) allows the virus to escape control by antivirals. Historically, the combination of ribavirin and interferon therapy has represented the only treatment option for the disease. Currently, several new treatment options are emerging and are available to a large part of the affected population. In addition, the search for new substances with antiviral activity against HCV continues, promising future improvements in treatment. Researchers should consider the mutation capacity of the virus and the other variables that affect treatment success.
