Also, the ITGAX (which encodes for dendritic cell marker CD11c), CD8A (a marker of CD8+ T cell), and MS4A1 (which encodes for B‐cell marker CD20) genes presented markedly high expression in STING‐high SCLC tumors, and they positively correlated with STING expression (Figure 3G, Figure S3C,D). Here, CD8A is linked to small cell lung carcinoma.
