CXCL10 and urinary bladder cancer: The results showed that the expression of IRGs was closely correlated with immune cell infiltration (Figure 3A), revealing that high expression of IRGs, especially of chemokines that recruit T cells, such as CXCL9, CXCL10, CXCL11, etc., could induce an increase in immune cell infiltration in bladder cancers of the hot tumor subtype.
