CXCL11 and cervical carcinoma: Moreover, it has been reported in the literature that tumor cells affect the expression of PD-L1 in cells by autocrine CXCL11 [31, 32], so we have reason to believe that EphA2 upregulates PD-L1 through autocrine chemokine CXCL11, thereby promoting the occurrence and development of cervical carcinoma.
