Liver-sinusoidal endothelial cells (LSEC) play an essential role as protective scavenger cells for the
whole organism as stabilin-1/2-deficient mice show severe organ dysfunction. Comprehensive
molecular analyses revealed several functional gene clusters including transcription factors such as
GATA4 to determine the organ-specific differentiation program of LSEC. The major aim for the next
funding period is to investigate hepatic endothelial differentiation and reprogramming. To this end the
inter-connective network of transcription factors, miRNAs, signalling pathways and their target genes in
LSEC differentiation and their impact on LSEC functions will be analysed. To study decisive LSEC
genes such as Gata-4 and BMP2 in liver biology and pathology in vivo, a LSEC-specific (stab2) Credeleter
mouse will be generated. |
