abstract = {Notably, the majority of papillomaviruses associated with a
high cancer risk have the potential to translate different
isoforms of the L1 major capsid protein. In an infection
model, the cutaneous Mastomys natalensis papillomavirus
(MnPV) circumvents the humoral immune response of its
natural host by first expressing a 30 amino acid extended L1
isoform (L1LONG). Although inducing a robust seroconversion,
the raised antibodies are not neutralizing in vitro. In
contrast, neutralizing antibodies induced by the
capsid-forming isoform (L1SHORT) appear delayed by several
months. We now provide evidence that, although L1LONG
vaccination showed a strong seroconversion, these antibodies
were not protective. As a consequence, virus-free animals
subsequently infected with MnPV still accumulated high
numbers of transcriptionally active viral genomes,
ultimately leading to skin tumor formation. In contrast,
vaccination with L1SHORT was completely protective. This
shows that papillomavirus L1LONG expression is a unique
strategy to escape from antiviral immune surveillance.},
