CD8A and diffuse large B-cell lymphoma: A manual gating strategy was developed (Figure 2e, Supplementary figure 4a) and confirmed the prevalence of MC09 and MC11, but not MC10, in DLBCL biopsies compared to control LN (Figure 2f) or paired DLBCL PBMCs (Supplementary figure 4b), emphasising the prominence of these two CD8+ follicular subsets in the DLBCL TME.
