Transcriptional regulation during CD4+ T cell fate decisions enables their differentiation into distinct states, guiding immune responses toward antibody production via Tfh cells or inflammation by Teff cells. Tfh-Teff cell fate commitment is regulated by mutual antagonism between the transcription factors Bcl6 and Blimp-1. Here we examined how T cell receptor (TCR) signals establish and arbitrate...
Data from recent studies suggest that donor fasting imparts a beneficial effect on the viability of transplanted hepatic allografts. Because starvation may temporarily inactivate Kupffer cells, and because these cells are the likely mediators of liver injury after prolonged preservation-reperfusion, the purpose of this study is to establish a link between improved organ viability and Kupffer cell...
Despite improvements in preservation solutions, hepatic allografts continue to be lost from primary nonfunction. Previous work by this group and others has established that donor fasting improves the viability of hepatic allografts. We have also established an association between viability of stored organs and serum TNF levels. The purpose of this study was to determine whether improved viability...
