Expression of CD71 on neutrophils correlated positively with CD86, CD80 and CD69 on neutrophils in PDAC patients. Expression of CD86 on neutrophils in clinical control (n = 14) and PDAC patients and the correlation of CD86 with CD71 on neutrophils in PDAC patients (n = 70) (A); expression of CD80 on neutrophils in clinical control (n = 12) and PDAC patients and the correlation of CD80 with CD71 on neutrophils in PDAC patients (n = 70) (B); expression of CD69 on neutrophils in clinical control (n = 9) and PDAC patients and the correlation of CD69 with CD71 on neutrophils in PDAC patients (n = 70) (C); expression of PDL-1 on neutrophils in clinical control (n = 21) and PDAC patients and the correlation of PDL-1 with CD71 on neutrophils in PDAC patients (n = 70) (D); **p < 0.01.
