Our results demonstrate that DOC induces CD8+ T cell recruitment to the tumor microenvironment by enhancing the secretion of HMGB1 and CXCL11, thus improving the anti-tumor efficacy, indicating that modulating the HMGB1-CXCL11 axis might be helpful for NSCLC treatment. Here, CXCL11 is linked to non-small cell lung carcinoma.
