Detection of CXCR6 on infiltrated PMN of patients with pancreatic carcinoma. Expression of CXCR6 on PMN of patients (n = 6) with pancreatic carcinoma was determined with confocal laser scan microscopy by using colocalization of CD66b (a), a marker molecule for PMN, and CXCR6 (b). In (c) a representative example of the overlay of both stainings revealing CXCR6-positive PMN infiltrated in pancreatic carcinoma specimens is given. The appropriate isotype negative controls are presented in (d) and (e).
