CXCR2 and neoplasm: Yet, in the context of anti‐tumour therapy, using a mouse model of colon carcinoma, Brackett and colleagues demonstrated that photodynamic therapy (PDT) was also associated with the rapid recruitment of neutrophils (i.e. within 4 h post PDT) into tumour‐draining LNs through HEVs in an IL‐17 and CXCR2/CXCL2 (but not CXCL1)‐dependent manner 58, 107.The authors also showed the importance of L‐selectin and of peripheral node addressin (PNAd) in neutrophil entry through HEVs in this model.
