The data lacked significant power to unmix CXCR5 on CD4+ T cells by CSx; however, tumor cell-specific CXCL13 expression was positively correlated with bulk mRNA CXCR5 expression (Fig. 5o) and a strong receptor-ligand interaction was predicted between CXCL13 in tumor cells and CXCR5 in CD4+ T cells (Supplementary Fig. 8d), suggesting a chemoattractant recruitment mechanism. The gene discussed is CXCL13; the disease is neoplasm.
