Figure 1. Recipient CC1 signaling mitigates hepatic IRI and suppresses NF-kB p65 in mouse OLT. Mouse WT livers subjected to 18 hours of cold storage were transplanted into WT or CC1KO syngeneic recipients (n ¼ 6–8/group). OLT/serum samples were analyzed 6 hours after reperfusion. The sham group (n ¼ 5) underwent the same procedures except for OLT. (A) Representative H&E and TUNEL staining. DAPI, 40,6-diamidino-2-phenylindole. Scale bars ¼ 100 mm. (B) Suzuki’s histologic grading of liver IRI and quantiﬁcation of TUNELþ cells/HPF. (C) sAST/sALT and (D) lactate dehydrogenase (LDH) levels (U/L). Quantitative reverse transcription polymerase chain reaction–assisted OLT detection of (E) IFN-gamma, IL6, IL17, and gran- zyme B/perforin 1, and (F) TLR4, IL1b, and TNF-a (n ¼ 6–7/group). Data normalized to hypoxanthine guanine phosphor- ibosyltransferase gene expression. (G) Western blot–assisted detection of phosphorylated (p)-IkBa, IkBa, p-NF-kB p65, NF-kB p65, and vinculin (VCL). The relative intensity ratio of p-IkBa/IkBa and p-NF-kB p65/NF-kB p65 (n ¼ 4/group) is shown. Data are shown as mean ± standard error of the mean *P < .05, **P < .01, Student t test.

MD1003 accelerates the differentiation potential of murine OPCs in vivo. ( A – E ) The percentage of the total Olig2+ cells (red) over Hoechst ( H in blue) increases over time for both vehicle- and MD1003-treated groups. MD1003 significantly increases the number of murine OPC at 12 wpt ( F ) and the OPC differentiation potential (CC1+ in green) at 20 wtp ( G ) in the brain of shiverer mice. There is no effect on the percentage of Ki67+OLIG2+/Hoechst+ cells ( H ) or Ki67+OLIG2+/OLIG2+ cells ( I ).
