CD8+ CTL responses are critical for eliminating virus infected cells in acute infection and in controlling virus replication during chronic infection. Despite evidence of potent HIV-1-specific CD8+ CTL responses during the earliest stage of acute infection leading to replacement of founder virus sequence(s) and resolution of peak viral load, in the majority of infected individuals, these responses are inadequate to prevent the establishment or control of persistent infection. Protective CD8+ CTL responses have yet to be achieved by vaccine approaches for HIV-1 or other viruses causing persistent infections, Mycobacterium tuberculosis, malaria, and cancer. Understanding the limitations of CD8+ CTL responses to keep pace with the diversity of rapidly evolving virus in the case of HIV-1 and HCV and to overcome the diverse and complex mechanisms persistent pathogens employ to escape immune recognition should lead to more effective prophylactic and therapeutic approaches for these diseases. Recent technological advances including single genome amplification (SGA) of plasma viral RNA along with direct amplicon sequencing to identify virus quasispecies, bioinformatics, and statistical methods for the systematic identification of HLA-class I associated escape mutations, and mathematical models that better define the kinetics of virus replication and decay, have provided significant insight into mechanisms of viral transmission and sequence evolution, virus-host interactions, and HIV-1 pathogenesis. In this review we attempt to integrate recent findings from studies in HIV-1, persistent virus infections, and cancer that predict effective T cell responses and suggest approaches that could shift the balance of control in favor of the host immune response. Here, we highlight factors considered essential for effective HIV-1 vaccine CD8+ T cell responses: vaccine antigens, quality, magnitude and breadth, mucosal targeting, and formation of CD8+ T cell mucosal memory.
