PDCD1LG2 and gastric cancer: To see whether similar phenotypes might be exhibited on the neutrophils in GC, we first examined the expressions of PD‐L2 and FasL, and found that intratumoral neutrophils expressed significantly higher immunosuppressive molecules FasL and PD‐L2 than those from peritumoral and non‐tumor tissues whereas peripheral neutrophils expressed little FasL nor PD‐L2 (Figure S3A–C, Supporting Information).
