IL4 has been shown to suppresses liver TNF-a mRNA expression, neutrophil accumulation and liver injury (52) whilst IL-10 has been shown to protect against hepatic ischemia-reperfusion injury by suppressing NFkB activation and subsequent expression of pro-inflammatory mediators (53) and importantly both have been shown to be upregulated following MAPC cell administration (54, 55). This evidence concerns the gene IL4 and ischemia.
