By comparing the functional capacities, we did not observe differences in the degranulation (Figure 5) and cytokine secretion (Figure S10) of FcεRIγ− adaptive NK cells obtained from HCMV+ HCC patients compared to HCMV+ control cohorts, neither after stimulation with tumor cells (Figure 5A–C, Figure S10A–F), nor with cytokines (Figure 5D, Figure S10G,H), nor after CD16 crosslink (Figure 5E, Figure S10K,L), nor after co-cultivation with activated autologous CD8+ T cells (Figure 5F, Figure S10I,J). Here, CD8A is linked to hepatocellular carcinoma.
