Subsequently, we subdivided the T cells into CASP8 high-expressing T cells and CASP8 low-expressing T cells according to the median value, and we found that the proportion of CASP8 high-expressing T cells was much higher than that of normal cells in tumor tissues but still lower than that of CASP8 low-expressing T cells (Figure 2D). The gene discussed is CASP8; the disease is neoplasm.
