NCAM1 and lung adenocarcinoma: A comparison of different CD3+ T cell subpopulations, such as CD4+, CD8+, CD4+/CD25+ regulatory, NKG2D+, and CD94+ T cells revealed no major differences, apart from a significant increase in the subpopulation of CD3+/CD56+ NKT cells in patients with adeno lung carcinomas compared to healthy controls (p = 0.038) (Figure 4B).
