CD19 and non-Hodgkin lymphoma: For in-depth and high-dimensional analysis, we performed unsupervised clustering of 75,000 CD3+ T-cells (CD3+CD19−) from concatenated FCS data files for each group after mass cytometry: 10 HIV-negative (12 data files), 20 HIV-positive cART-naïve (22 data files), and 10 HIV-positive pre-NHL (cART-naïve) samples (11 data files) (Figure 1).
