Lymphoid aggregate polyp.

Abstract. Regulatory T cells seem to play a central role in maintaining immune tolerance in the gut mucosa. Previously we have shown that interleukin (IL)-10 is produced at high levels in the inflamed colonic tissue of ulcerative colitis (UC) patients. The cellular source was CD4 + T cells, suggesting local activation of regulatory T cells.
