CD4 and tuberculosis: CD4 TB cells were cultured in the presence or absence of IL‐2 (TB IL‐2 and TB IL‐2nil), non‐apoptotic live cells were purified (Fig EV1B) before DNase I treatment, and the DHSs were ranked according to the fold change in the DNA sequence tag count of peaks in TB IL‐2 compared to TB IL‐2nil (Figs 2A and EV1C).
