'Naïve' and 'memory' CD4+ T-cells and T-cell receptor (TCR) V beta repertoire dynamics are independent of the levels of viremia following HIV seroconversion.

The progression of 'naive' and 'memory' T-cells and the T-cell receptor Vbeta (TCR Vbeta) repertoire dynamics within the peripheral CD4+ T-cell compartment were studied in individuals following HIV seroconversion. Profound TCR Vbeta repertoire perturbations were observed within the CD4+ T-cell pool in treatment-naive patients regardless of their levels of viremia during the first 6-8 months after seroconversion. The ratio of 'naive' to 'memory' CD4+ T-cells as well as the TCR Vbeta repertoire dynamics did not appear to correlate with absolute numbers of CD4 T-cells.
