Comparison between the groups showed significantly more GFAP expression (p < 0.05) in the Peyer’s patches of CD patients when compared to non-IBD controls (Figure 3B), and less GFAP expression (p = 0.13) in lamina propria of CD patients when compared to non-IBD controls (Figure 3B). The gene discussed is GFAP; the disease is inflammatory bowel disease.
