IL17A and non-small cell lung carcinoma: Moreover, the abundance of IL-17A in Th17 cells (8.77 ± 1.56% vs. 3.85 ± 0.39%), Tc17 cells (7.34 ± 1.09% vs. 2.85 ± 0.34%) and γδT17 cells (14.27 ± 1.75% vs. 4.88 ± 0.30%) isolated from NSCLC specimens was significantly higher than those isolated from paracancerous ones (all p < 0.0001).
