Prophylactic immunization against human papillomaviruses (HPVs) aims preferentially at the generation of antibodies, which are directed against the virus capsid proteins. DNA-free virus-like particles or their pentameric subunits, the capsomeres represent suitable antigens. Here we investigated if anti-HPV16 L1 specific antibodies and L1-specific CTL induced by intranasal immunization with capsomeres in sera and vaginal washings of C57Bl6 mice can be enhanced by co-application of the non-toxic cholera toxin adjuvants CTA1-D2D1 or CTB. We found that CTA1-D2D1 elevated L1-specific serum IgG antibodies in a dose-dependent manner and both CTA1-D2D1 and CTB significantly increased L1-specific IgA antibody levels in the vaginal lumen. Furthermore, CTA1-D2D1 and CTB enhanced L1-specific CTL responses.
