Immune microenvironment analysis. A Boxplot showing the differences in immunogenicity score (IS) between tissues from the DPN patients and HC participants. B Heatmap showing the association between the immunogenicity score (IS) of 24 immune cells in DPN patients. C Heatmap showing the association between the four hub genes and the immunogenicity score (IS) of 24 immune cells in DPN patients. D Scatter plot showing the association between the expression level of the HSPA5 gene and the IS of neutrophils in DPN patients
