Oral glycine and Pro‐Hyp attenuated the recruitment of inflammatory cells into the colonic tissue (Figure 1f,g), possibly owning to their prevention of leukocytosis and lymphocytosis (Figure 5a,b), and this may explain their effectiveness in suppressing the colonic increase in IL‐6 and TNF‐α (Figure 3b,c). Here, IL6 is linked to Increased total leukocyte count.
