Computational designing of a poly-epitope fecundity vaccine for multiple species of livestock.

Inhibin and follistatin are known to reduce fecundity by inhibiting the actions of activin and FSH. Thus, the immunoneutralization of these hormones is a rational proposal for augmenting reproductive performance. The present study describes a comprehensive computational methodology comprising of a consensus approach of several B- and Th-cell epitope prediction tools for the identification of epitopic regions within the structure of these hormones that can be incorporated into a poly-epitope fecundity vaccine. The proposed peptide (RGD-WSPAALRLLQRPPEEPA-KK-YSFPISSILE) should be effective in multiple animal species, generating good immunological memory.
