CXCL10 and type 1 diabetes mellitus: We found a significant correlation between the density of EV-positive cells in the small bowel mucosa and the levels of IP-10 (r = 0.52; P = 0.04) and sTNFRII (r = 0.45; P = 0.02) in CD patients, while CD patients with coexisting T1D showed a very strong correlation between the density of EV-positive cells and level of GM-CSF (r = 0.91; P = 0.006).
