Figure 8. Association between FPN1 and immune cell infiltration in lung cancer. (A) FPN1 showed a significant correlation with the infiltrating abundance of CD4+ T cells, CD8+ T cells, B cells, neutrophils, macrophages and dendritic cells using the TIMER database. (B, C) The relationship between FPN1 and the infiltrating abundance of different immune cells was investigated using CIBERSORT. All results are shown in a circos plot.
