This session explores the intricate signaling pathways and metabolic networks that govern liver injury, repair, and chronic disease progression. Presentations will cover hepatocyte-stellate cell interactions, nuclear receptor signaling, autophagy zonation, and the molecular regulation of regeneration and fibrosis. Through multiomics and tissue-specific analyses, these studies illuminate how dysregulation of cellular communication and metabolism contributes to conditions such as steatohepatitis, fibrosis, sarcopenia, and Type II diabetes.
