IL13RA1 and cancer: These IL-13Rα1+ cells were highly significantly increased (p<0.001) in muscle from fibrotic CD intestine compared to all other groups (Figure 6A) and were rarely observed in muscle tissue from cancer control or inflamed UC intestine (Figure 4 panel A, Figure 6A) and there was an uneven distribution of KIR+ cells in fibrotic muscle tissue, with the highest numbers in the inner muscle, and significantly fewer in the mucosa compared to all other regions (p<0.01 all comparisons) (Figure 6B).
