Application progress of early nutrition intervention in patients with hepatocellular carcinoma after liver transplantation

Figure 1 Anatomical microstructure of liver. NAD kinase plays a role in the development of inflammation and liver fibrosis by regulating metabolic and antioxidant mechanisms in the liver. NADK: NAD kinase.

Figure 2 Gut-liver axis. The occurrence of ischemia reperfusion injury in the liver can trigger immune and inflammatory responses, resulting in the aggregation of neutrophils, macrophages and other immune cells at the injury site and the release of a large number of pro-inflammatory factors, thereby affecting the functions of the intestine and liver. AMP-activated protein kinase pathway plays an important regulatory role in this process. IRI: Ischemia/reperfusion injury; IL: Interleukin; AMPK: AMP-activated protein kinase; SIRT1: Sirtuin 1; GSDMD: Gasdermin-D.
