CCR2+ Monocyte-Derived Ly6C-F4/80+ Fibrocytes Inhibit Collagen Degradation and Contribute to the Development of Colon Fibrosis Via Production of TIMP-1

Conclusions: Circulating CCR2+ monocytes migrate into the inflamed colon via CCL2/CCR2 axis and differentiate into CCR2+Ly6C-F4/80+ fibrocytes, which inhibit collagen degradation and contribute to the development of colon fibrosis by the production of TIMP-1.DisclosuresMasuya: Kyowa Hakko Kirin Co., Ltd.: Research Funding.
