Abstract__ Background Human papillomavirus HPV L1 capsid proteins can self-assemble into pentamers capsomeres that are immunogenic and can elicit neutralizing antibodies. Structural modelling of L1 inter-pentameric interactions predicts that helix 4 h4 of each of the five L1 monomers project laterally and outwards from the pentamer. We sought to utilize HPV L1 capsomeres as a vaccine platform by engineering heterologous epitopes within L1 derivatives deleted for h4 domain. Results We used baculovirus - .
