Chlamydia trachomatis Pgp3 protein-induced immunoprotection is effective but incomplete, which requires the suitable adjuvants to enhance its immune response. Within this context, Hepatitis B core virus-like particles (HBc-VLP) emerge as nanoscale protein particles capable of incorporating either endogenous or exogenous antigens or epitopes. In this study, HBc-Pgp3 chimeric protein was accomplished by integrating the identified dominant epitope of the Pgp3 protein into the major immunodominant region of a truncated HBc-VLP, which was realized i...
