Fig. 2From: Deep sequencing of the HIV-1 polymerase gene for characterisation of cytotoxic T-lymphocyte epitopes during early and chronic disease stagesFrequently recognized Pol CTL epitopes in early and chronic HIV infection. These are epitopes that were recognized by more than one participant. A Epitopes within the protease (PR) region. B Epitopes within the reverse transcriptase (RT) region. C Epitopes within the integrase (IN) region. Many epitopes were located within RT and IN as compared to PR, and most were found in chronic HIV infection.
