Chimeric human papillomavirus type 16 (HPV-16) L1 particles presenting the common neutralizing epitope for the L2 minor capsid protein of HPV-6 and HPV-16.

ABSTRACT: Both the Human papillomavirus (HPV) major (L1) and minor (L2) capsid proteins have been well investigated as potential vaccine candidates. The L1 protein first oligomerizes into pentamers, and these capsomers assemble into virus-like particles (VLPs) that are highly immunogenic. Here we examine the potential of using HPV type 16 (HPV-16) L1 subunits to display a well-characterized HPV-16 L2 epitope (LVEETSFIDAGAP), which is a common-neutralizing epitope for HPV types 6 and 16, in various regions of the L1 structure. The L2 sequence was introduced by PCR (by replacing 13 codons) into sequences coding for L1 surface loops D-E (chideltaC-L2), E-F (chideltaA-L2), and an internal loop C-D (chideltaH-L2); into the h4 helix (chideltaF-L2); and between h4 and beta-J structural regions (chideltaE-L
