Analysis of T cell subpopulations in discordant couples showed no activation of a specific marker between discordant positives and negatives and the expression of T cell subpopulations was comparable. The expression of activation markers was in significantly (P<0.05) higher in concordant couples compared with discordant positives and apparently healthy control, indicating lower immune activation in discordant couples. Moreover, we observed in discordant positives, certain markers (CD4+CD45RA-CD27-) in a high proportion (>30%), similar to non-progressors. CCR5 co receptors were significantly (P<0.05) lower in discordant couples when compared with concordant couples and healthy control. In discordant negatives CD4 and CD8 cells were higher similar with healthy negative controls. Unlike the concordant couples, immune activation markers were significantly low and expressed significantly lower CCR5 receptors. However, high memory T-cells was observed.
