CD4 and neoplasm: The expression of activated dendritic cells and activated CD4 T cells showed a high correlation with the tumour-related risk score (Figure 5E), with a negative correlation between the expression of activated dendritic cells and the risk score (p<0.001) and a positive correlation between the expression of activated CD4 T cells and the lysosomal pathway-related risk score (p<0.05), with a significant linear relationship.
