CXCR5 and neoplasm: Biswas et al demonstrated that co‐expression of the ligand‐receptor pair CXCL13–CXCR5 directly regulates the epithelial to mesenchymal transition in tumors and enhances tumor migration and invasion,40 indicating that CXCL13 may be a valuable prognostic indicator and a therapeutic target for patients with advanced LUAD.
