Consequently, the correlation between PLAUR expression and the infiltration of different immune cells was examined (Fig. 6B), and a significant positive correlation was found between the expression of PLAUR and the expression of all immune cells in NSCLC, including B-lymphocytes, CD8+ T-cells, CD4+ T-cells, macrophages, neutrophils, and dendritic cells. The gene discussed is CD4; the disease is non-small cell lung carcinoma.
