abstract = {Licensed L1-VLP-based immunizations against high-risk
mucosal human papillomavirus (HPV) types have been a great
success in reducing anogenital cancers, although they are
limited in their cross-protection against HPV types not
covered by the vaccine. Further, their utility in protection
against cutaneous HPV types, of which some contribute to
non-melanoma skin cancer (NMSC) development, is rather low.
Next generation vaccines achieve broadly cross-protective
immunity against highly conserved sequences of L2. In this
exploratory study, we tested two novel HPV vaccine
candidates, HPV16 RG1-VLP and CUT-PANHPVAX, in the
preclinical natural infection model Mastomys coucha. After
immunization with either vaccines, a mock control or MnPV
L1-VLPs, the animals were experimentally infected and
monitored. Besides vaccine-specific seroconversion against
HPV L2 peptides, the animals also developed cross-reactive
antibodies against the cutaneous Mastomys natalensis
papillomavirus (MnPV) L2, which were cross-neutralizing MnPV
pseudovirions in vitro. Further, both L2-based vaccines also
conferred in vivo protection as the viral loads in plucked
hair after experimental infection were lower compared to
mock-vaccinated control animals. Importantly, the formation
of neutralizing antibodies, whether directed against L1-VLPs
or L2, was able to prevent skin tumor formation and even
microscopical signs of MnPV infection in the skin. For the
first time, our study shows the proof-of-principle of next
generation L2-based vaccines even across different PV genera
in an infection animal model with its genuine PV. It
provides fundamental insights into the humoral immunity
elicited by L2-based vaccines against PV-induced skin
tumors, with important implications to the design of next
generation HPV vaccines.},
