CD4 and glioblastoma: Using the TIMER database, WSCD2 mRNA expression in LGG and GBM, respectively, was found to correlate with the expressions of B cells (r = 0.032, p > 0.05; r = −0.378, p < 0.01), CD8+ T cells (r = 0.08, p > 0.05; r = 0.039, p > 0.05), CD4+ T cells (r = 0.066, p > 0.05; r = −0.57, p < 0.01), macrophages (r = −0.094, p > 0.05; r = −0.508, p < 0.01), neutrophils (r = 0.146, p = > 0.05; r = −0.384, p < 0.01), and dendritic cells (r = −0.199, p < 0.05; r = −0.495, p < 0.01) (Fig. 1C).
