scRNA-seq data analysis on tumors from a cohort of four glioblastoma patients41 demonstrated that LDHA was highly expressed in both glioblastoma cells and CD68+CX3CR1- macrophages, but not in CD68+CX3CR1+ microglia (Supplementary Fig. S9b–e). The gene discussed is CX3CR1; the disease is glioblastoma.
