In ADC specimens from smokers, using the distance analysis, we observed a significant close median distance from malignant cells to suppressive TAIC phenotypes such as PD-L1 + T-cells, CD3 + CD8 + cytotoxic T-cells expressing PD-L1, macrophages expressing PD-L1, and ICOS + B-cells compared with nonsmokers. This evidence concerns the gene CD8A and AIDS dementia complex.
