Dominant induction of vaccine antigen-specific cytotoxic T lymphocyte responses after simian immunodeficiency virus challenge

► We examined CTL immunodominance after SIV challenge in vaccinated macaques. ► Vaccine antigen-specific CTL responses were induced dominantly post-challenge. ► SIV non-vaccine antigen-specific CTL induction post-challenge was delayed. ► These imply an influence of vaccination on immunodominance pos...

description ► We examined CTL immunodominance after SIV challenge in vaccinated macaques. ► Vaccine antigen-specific CTL responses were induced dominantly post-challenge. ► SIV non-vaccine antigen-specific CTL induction post-challenge was delayed. ► These imply an influence of vaccination on immunodominance post-viral exposure. ► This study provides insights into CTL antigen design in AIDS vaccine development. Cytotoxic T lymphocyte (CTL) responses are crucial for the control of human and simian immunodeficiency virus (HIV and SIV) replication. A promising AIDS vaccine strategy is to induce CTL memory resulting in more effective CTL responses post-viral exposure compared to those in natural HIV infections. We previously developed a CTL-inducing vaccine and showed SIV control in some vaccinated rhesus macaques. These vaccine-based SIV controllers elicited vaccine antigen-specific CTL responses dominantly in the acute phase post-challenge. Here, we examined CTL responses post-challenge in those vaccinated animals that failed to control SIV replication. Unvaccinated rhesus macaques possessing the major histocompatibility complex class I haplotype 90-088-Ij dominantly elicited SIV non-Gag antigen-specific CTL responses after SIV challenge, while those induced with Gag-specific CTL memory by prophylactic vaccination failed to control SIV replication with dominant Gag-specific CTL responses in the acute phase, indicating dominant induction of vaccine antigen-specific CTL responses post-challenge even in non-controllers. Further analysis suggested that prophylactic vaccination results in dominant induction of vaccine antigen-specific CTL responses post-viral exposure but delays SIV non-vaccine antigen-specific CTL responses. These results imply a significant influence of prophylactic vaccination on CTL immunodominance post-viral exposure, providing insights into antigen design in development of a CTL-inducing AIDS vaccine.
