We employed Spearman correlation to investigate the correlation between LAMP2 expression and immune cell infiltration level using TCGA data quantified as the ssGSEA score and revealed 15 types of immune cells significantly correlated with LAMP2 expression (Figure 7(a)), indicating the vital role of LAMP2 in the immune infiltration in prostate cancer. This evidence concerns the gene LAMP2 and Familial prostate cancer.
