As shown in Fig. 8, we found a positive association between LAG3 expression and tumor infiltration of CD8 + central memory T cell in CESC, KIRC, SKCM, OV, UCEC, etc. Additionally, LAG3 expression exhibited a positive correlation with infiltration of B cell in LUAD, PAAD, OV, SKCM, TGCT and UCEC. The gene discussed is LAG3; the disease is neoplasm.
