Figure 2F exhibited a heatmap of clinicopathological characteristics. Besides, we have evaluated the correlation between the subtypes and the characteristics of the tumor immune microenvironment. The results show differences in immune cell infiltration (Figure 2G) and immune function (Figure 2H) between the two subtypes. Compared with pyroptosis cluster B, activated B cells, CD8+ T lymphocytes, and natural killer T lymphocytes were more enriched in cluster A. Meanwhile, cytolytic activity and type I IFN response in pyroptosis cluster A have a higher score. The gene discussed is CD8A; the disease is neoplasm.
