In the AML_GSE116256 dataset, FLT3LG is mainly expressed in CD4+ T cells, but compared with the PBMC_30K_10× dataset, the expression level of FLT3LG is remarkably reduced (Figures 6B, D), and FLT3 is mainly expressed in leukemia cells and precursor cells (Figure 6F). The gene discussed is FLT3LG; the disease is leukemia.
