Furthermore, the occurrence of MPR is more likely to happen in high delta CD4+ T cells and high delta CD4+ Tcon groups (p = 0.025, OR = 6.000, 95% CI = 1.248–28.840; p = 0.025, OR = 6.000, 95% CI = 1.248–28.840), but patients with non-small cell lung cancer (NSCLC) exhibiting low levels of delta CD8+ Trm cells are more likely to achieve MPR (Figure 4A). Here, CD8A is linked to non-small cell lung carcinoma.
