Next, we further used the CIBERSORT algorithm to investigate the tumor-infiltrating immune cells, we found that the expression of SLA2 was positively correlated with the infiltration of B cells, cluster of differentiation 8-positive T cells (CD8 + T cells), cluster of differentiation 4-positive T cells (CD4 + T cells), Macrophages cells, Neutrophils cells, and Dendritic cells (Fig. 4B). Here, SLA2 is linked to neoplasm.
