We found that the expression levels of biomarkers of CD8+ T cells (CD8A and CD8B), T cells (CD3D, CD3E, and CD2), B cells (CD19 and CD79A), monocytes (CD86 and CD115), and TAMs (CD68 and IL10) positively correlated with the expression levels of JAK3 and TYK2 in STAD. This evidence concerns the gene CD2 and gastric adenocarcinoma.
