Memory (22.6%) and naïve (16.1%) B cells were the most abundant immune infiltrates in DLBCL (Fig. S1), followed by tumor-related macrophages (M0 11.7%, M2 8.2%, and M1 7.4%), CD4+ (10.3%) and CD8+ (8.2%) T cells, resting (2.3%) and activated (0.6%) NK cells, and Tregs (1.4%). This evidence concerns the gene CD8A and diffuse large B-cell lymphoma.
