    • Abstract

       

      Eight liver cell types were isolated using the methods of Percoll density gradient centrifugation and immunomagnetic beads to explore effects of histidine catabolites on rat liver regeneration. Rat Genome 230 2.0 Array was used to detect the expression profiles of genes associated with metabolism of histidine and its catabolites for the above-mentioned eight liver cell types, and bioinformatic and systems biology approaches were employed to analyse the relationship between above genes and rat liver regeneration. The results showed that the urocanic acid (UA) was degraded from histidine in Kupffer cells, acts on Kupffer cells itself and dendritic cells to generate immune suppression by autocrine and paracrine modes. Hepatocytes, biliary epithelia cells, oval cells and dendritic cells can convert histidine to histamine, which can promote sinusoidal endothelial cells proliferation by GsM pathway, and promote the proliferation of hepatocytes and biliary epithelia cells by GqM pathway.
