  ABSTRACT: The development of animal models of HPV infection has given investigators a new set of tools to expand basic knowledge of the early events of infection in vivo. The use of HPV pseudovirions, in which the viral genome has been replaced with a reporter pseudogenome, in combination with advanced imaging techniques has facilitated and simplified studies using these models. Herein we provide details for a murine model of cervicovaginal HPV infection in conjunction with several methods for imaging and quantitating the transduced genes, both ex vivo and in vivo.

  ABSTRACT: The majority of HIV infections occur via mucosal transmission. Vaccines that induce memory T and B cells in the female genital tract may prevent the establishment and systemic dissemination of HIV. We tested the immunogenicity of a vaccine that uses human papillomavirus (HPV)-based gene transfer vectors, also called pseudovirions (PsVs), to deliver SIV genes to the vaginal epithelium. Our findings demonstrate that this vaccine platform induces gene expression in the genital tract in both cynomolgus and rhesus macaques. Intravaginal vaccination with HPV16, HPV45, and HPV58 PsVs delivering SIV Gag DNA induced Gag-specific Abs in serum and the vaginal tract, and T cell responses in blood, vaginal mucosa, and draining lymph nodes that rapidly expanded following intravaginal exposure to SIV(mac251.) HPV PsV-based vehicles are immunogenic, which warrant further testing as vaccine candidates for HIV and may provide a useful model to evaluate the benefits and risks of inducing high levels of SIV-specific immune responses at mucosal sites prior to SIV infection.
