\n\nConclusions: LDLT recipients, despite lower acuity of disease, have higher hospitalization requirements when compared with DDLT recipients. Continuing efforts are warranted to reduce the incidence of complications requiring post-LDLT inpatient admission, with particular emphasis on biliary tract issues.”
“In the last few years, we have been functionally characterizing the promoter of the human mitochondrial citrate carrier (CIC). In this study we show that CIC silencer activity extends over 26 bp (-595/-569), which

specifically bind a protein present in HepG2 cell nuclear extracts. This transcription factor was purified by DNA affinity and identified as ZNF224. Overexpression of ZNF224 decreases LUC transgene activity in cells transfected with a construct containing the CIC silencer region, whereas ZNF224 check details CA3 cost silencing activates reporter transcription in cells transfected with the same construct. Moreover, overexpression and silencing of ZNF224

diminishes and enhances, respectively, CIC transcript and protein levels. Finally, ZNF224 is abundantly expressed in fetal tissues contrary to CIC. It is suggested that CIC transcriptional repression by ZNF224 explains, at least in part, the low expression of CIC in fetal tissues in which fatty acid synthesis is low. (C) 2009 Elsevier Inc.

“DNAX-activation protein 12 (DAP12), a transmembrane adapter, plays a major role in transducing activation signals in natural killer cells and various myeloid cells. Quantitative RT-PCR detected in normal mouse eyes considerable levels PD98059 mw of DAP12 and multiple DAP12-coupled receptors, in particular TREM-1, Clec5a and SIRPb1. The role of DAP12 and its receptors in experimental autoimmune diseases has been controversial. Here, we analysed the effect of DAP12 deficiency on the capacity of mice to mount immunopathogenic cellular responses to the uveitogenic ocular antigen and interphotoreceptor retinoid-binding protein (IRBP), and to develop experimental autoimmune uveitis (EAU).

Surprisingly, sequential analysis of EAU in mice deficient in DAP12 in two different animal facilities at first revealed enhanced disease as compared with wild-type mice, but when these mice were re-derived into a second, cleaner, animal facility, the response of control mice was essentially unchanged, whereas the DAP12 null mice were markedly hyporesponsive relative to controls in the new facility. Accordingly, when stimulated in vitro with IRBP, lymphocytes from the DAP12-deficient mice housed in the two facilities proliferated and produced opposite profiles of pro-inflammatory and anti-inflammatory cytokines, compared with their controls. These findings therefore demonstrate that the effects of DAP12 deficiency on development of autoimmune disease are dramatically affected by environmental factors.
