Figure 1From: P2X7 protein expression and polymorphism in non-small cell lung cancer (NSCLC) Immunohistochemical staining of P2X7 in lung cancers. (A and C) Low P2X7 expression levels in ADC (5%, 1+) and SCC (15%, 1+), respectively. (B and D) High P2X7 expression levels in ADC (80%, 2+) and SCC (70%, 2+), respectively.
