Which Tr1 Is Better for Transplant Tolerance Induction: Comparing the Tr1 Generated by IL-27 or TGF-βplus IL-27.
G. Gu, H. Hang, Q. Xia.
Department of Hepatic Surgery, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China
IL-10 producing T cells (Tr1) are important for the transplant tolerance induction. However, Tr1 can be induced in two methods: IL-27 or TGF-βplus IL-27. We…

Soluble Fibrinogen-Like Protein 2 Regulates Differentiation and Enhances Immunosuppressive Function of Myeloid-Derived Suppressor Cells in Allograft Immunity.
C. Yang, B. Peng, M. Xu, T. Zhu.
Urology, Zhongshan Hospital, Fudan University, Shanghai, China
Soluble fibrinogen-like protein 2 (sFGL2) is a novel immunoregulatory molecule, secreted mainly by regulatory T cells. CD11b+ Gr1+ myeloid-derived suppressor cells (MDSCs) are an important…
