CD8A and meningioma: The percentage of the 22 types of immune cells was visually displayed in Fig. 4A. The Pearson correlations among the 22 immune cell types’ infiltrations and the immune scores in meningioma patients showed that T cell CD8 were positively correlated to monocytes and negatively correlated with Mast cells activated; B cell memory were positively correlated with T cells regulatory Tregs, and negatively correlated with Eosinophils (Fig. 4B).
