ABSTRACT
The repertoire of Abs is generated by genomic rearrangements during B cell differentiation. Although V(D)J rearrangements lead to repertoires mostly different between individuals, recent studies have shown that they contain a substantial fraction of overrepresented and shared "public" clones. We previously reported a strong public IgHµ clonotypic response against the rhabdovirus viral hemorrhagic septicemia virus in a teleost fish. In this study, we identified an IgL chain associated with this public response that allowed us to characterize its functionality. We show that this public Ab response has a potent neutralizing capacity that is typically associated with host protection during rhabdovirus infections. We also demonstrate that the public response is not restricted to a particular trout isogenic line but expressed in multiple genetic backgrounds and may be used as a marker of successful vaccination. Our work reveals that public B cell responses producing generic Abs constitute a mechanism of protection against infection conserved across vertebrates.
