Similarly, we were unable to identify any overall statistically significant differences in the infection frequency of proviruses with an intact p24 ORF between the four cell subsets within this data, though we observed that DN, PD-1+ and DP cells had a higher estimated infection frequency of provirus with an intact p24 ORF compared to CTLA-4+ cells (Figure 6C). The gene discussed is PDCD1; the disease is infection.
