CD4 and posterior cortical atrophy: Likewise, we found B cell, Th1, Th2, macrophage (and macrophage M1), CAF, and mDC were positively associated with EZH2 gene copy number (all r > 0, p-value < 0.05), while T cell CD4+, T cell CD4+ non-regulatory, and T cell CD8+ were negatively associated with EZH2 gene copy number in PCa (all r < 0, p-value < 0.05) (Supplementary Figure S4B).
