CD4 and glioma: The results demonstrated that WSCD2 protein expression was weakly correlated with the protein expressions of CD20+ B cells (r = 0.288, p = 0.001), CD4+ T cells (r = 0.231, p = 0.026), CD8+ T cells (r = 0.215, p = 0.038), CD68+ macrophages (r = 0.136, p = 0.116), CD66B+ neutrophils (r = 0.242, p = 0.005), and CD83+ dendritic cells (r = 0.201, p = 0.016) in glioma tissues (Fig. 2B, 3A-E).
