CD8A and non-small cell lung carcinoma: Wang C25 collected 10 solitary ADC and 9 solitary SQCC lesions from 19 patients with non-small cell lung cancer (NSCLC), and the single-cell RNA sequencing (scRNA-seq) and mIHC analysis suggested that CD8 + T cells (p = 0.069), B cells (p = 0.020), Tregs (p = 0.007), and mast cells (p = 0.032) were more abundant in SQCC than in ADC.
