In NSCLC samples, the proportions of Plasma cells, T cells CD8, T cells CD4 naive, T cells regulatory (Tregs), Macrophages M0, Macrophages M1, Dendritic cells resting, and Neutrophils were elevated, whereas the proportions of T cells follicular helper, Dendritic cells activated, Monocytes, Mast cells resting, and Eosinophils were reduced. Here, CD4 is linked to non-small cell lung carcinoma.
