PDCD1 and non-small cell lung carcinoma: In accordance with our predictions, most of the patients with NSCLC with IFN-γ+ and TNF-α+ CD3 T cells activated by docetaxel and rocaltrol did not relapse; 1α,25(OH)2D3 level was marginally increased, but 1α,25(OH)2D3 level negatively correlated with PD-1 expression on CD8+ T cells (online supplemental figures S7E–G).
