Abstract
Using a panel of human T-cell receptor (TCR) variable region β chain (Vβ) polymerase chain reaction (PCR) primers, we performed cross-sectional and longitudinal analyses of the TCR Vβ repertoire in naive and HIV-1 infected chimpanzees. We demonstrate that our TCR PCR primer panel will support amplification of chimpanzee cDNA from most of the TCR Vβ families. However, no differences in TCR Vβ expression were found between the naive and HIV-1 infected chimpanzees, unlike the TCR Vβ repertoire perturbation found in HIV-1 infected human subjects. This finding suggests that a complete TCR repertoire in HIV-1 infected chimpanzees is associated with the maintenance CD4 + T-cell numbers and lack of progression to AIDS.
