FasL—T cells, NK cells, monocytes, and Paneth cells
(i) Fas—intestinal epithelial cells and T cells (ii) DcR3 (decoy)—activated T cells
Possible disruption of intestinal epithelium integrity by induction of epithelial cells apoptosis. Possible involvement in accumulation of proinflammatory T cells in intestinal lamina propria
TRAIL—intestinal epithelium, T cells, NK cells, and dendritic cells
(i) TRAIL-R1—almost all cell types (ii) TRAIL-R2—almost all cell types (iii) TRAIL-R3 (decoy)—almost all cell types (iv) TRAIL-R4 (decoy)—almost all cell types (v) OPG (decoy)—osteoclasts’ precursors, endothelial cells, and other cell types
Disruption of intestinal epithelium integrity by induction of epithelial cells apoptosis. Possible contribution to development of fistulas and strictures in CD patients
Possible upregulation of proinflammatory cytokines and infiltration of lamina propria by inflammatory cells. Induction of intestinal cells apoptosis in cooperation with IL-13
