Figure 1  

Intracellular cascades of the gp130 receptor. After interleukin 6 (IL-6) binding to gp80, two gp130 molecules homodimerise and activate JAK kinases which in turn phosphorylate the intracellular tyrosines of the gp130 receptor. Via the different phosphotyrosines, STAT1/3 and Ras dependent pathways are activated in the cell.

Figure 2  

The role of interleukin 6 (IL-6) in hepatocyte proliferation after partial hepatectomy. After partial hepatectomy, tumour necrosis factor α (TNF-α) activates IL-6 expression, most likely in Kupffer cells. TNF-α and IL-6 via the gp80/gp130 receptor complex in turn activate intracellular pathways in liver cells which are essential for triggering hepatocyte proliferation after hepatectomy.
