Additionally, a correlation was observed between the CRG score and infiltration of CD8 + T cells, naïve CD4 + T cells, activated memory CD4 + T cells, resting NK cells, M0 macrophages, and activated dendritic cells; however, only the correlation with CD8 + T cells was validated by the immune score (Fig. 5C), suggesting that the CRG score may be more closely related to immune cell infiltration in gliomas than the immune score. Here, CD8A is linked to central nervous system cancer.
