For other cell types, potential strong interactions between CAFs and T cells were observed via ligand–receptor interaction, such as GZMA‐F2R (Figure 7A), to induce tumour suppression and T cell‐mediated killing of tumour cells between cytoxic T and tumour cells in hepatocellular carcinoma.39 The gene discussed is GZMA; the disease is hepatocellular carcinoma.
