In harmony to the current results, exosomes obtained from BMDCs treated with IL‐10 were reported to be superior to those derived from immature DCs in terms of their ability to attenuate increased expression of TNF‐α, IL‐2 and interferon-gamma (IFN‐γ) in colon tissues, suppressing more effectively chemically induced colitis inflammation in rats [62]. The gene discussed is IL2; the disease is colitis.
