CLEC7A and colitis: DECTIN‐1 is expressed in freshly isolated human intestinal epithelial cells (IECs) and human IEC lines, but not in the analogous mouse cells.27 Stimulation of human IECs with β‐glucans induces IL‐8 and CCL2 secretion, which can be blocked by SYK inhibition,27 suggesting involvement of IECs in the development of colitis in humans.
