CD8A and hepatocellular carcinoma: The analysis also showed that the group with high FLAD1 expression had significantly lower enrichment scores for these cells than did the group with low FLAD1 expression (including cytotoxic cells, CD8+ T cells, neutrophils, DCs, Tregs, B cells, Th1 cells, and TCMs), highlighting the potential immunosuppressive role of high FLAD1 expression in HCC (Figures 8B, C; Supplementary Tables S9, 10).
