PDCD1 and infection: For DN, PD-1+ and DP cells, we found a strong positive association between the total infection frequency and infection frequency of proviruses with intact p24 (DN: r=0.78, 95% CI: 0.45, 0.92, p=0.0006; PD-1: r=0.96, 95% CI: 0.89, 0.99, p<0.0001; DP: r=0.78, 95% CI: 0.43, 0.92, p=0.001; Supplementary Figure 3A, B, D).
