CD4 and cancer: Using TIMER2.0,[31] cell type deconvolution analysis revealed that CXCL13 expression positively correlated with immune cell subsets known to promote antitumor immunity (e.g., DC cells, M1 macrophages, NK cells, and CD4+ and CD8+ T cell subsets) and inversely correlated with immunosuppressive subsets (e.g., cancer‐associated fibroblasts, M2 macrophages, and MDSCs) across cancers (Figure 1h).
