Single-cell RNA-sequencing combined with bulk RNA-sequencing analysis of peripheral blood reveals the characteristics and key immune cell genes of ulcerative colitis

Figure 8 Immune infiltration in patients with ulcerative colitis. A: Relative percentages of 22 immune cell subsets in ulcerative colitis (UC) samples; B: Pearson correlation among the 22 immune cell types. Blue indicates a positive correlation, and red indicates a positive correlation; C: Differences in the immune cell content between controls and patients with UC. Blue indicates controls, and pink indicates patients with UC. ^aP < 0.05, ^bP < 0.01, ^cP < 0.001; D-F: Pearson correlation analysis of the three core genes with immune cells. Orange indicates a positive correlation, and purple indicates a negative correlation.
