Refining the role of epicardial adipose tissue in non-alcoholic fatty liver disease.

Hepatology international·2019

Non-alcoholic steatohepatitis (NASH) is rising with metabolic syndrome. Animal models help study NASH mechanisms, focusing on liver fat, inflammation, and fibrosis to understand human non-alcoholic fatty liver disease.

Area of Science:

  • Hepatology and metabolic disease research.

Background:

  • Non-alcoholic steatohepatitis (NASH) incidence is increasing globally.
  • NASH is associated with visceral adiposity, insulin resistance, dyslipidemia, and type 2 diabetes mellitus.
  • The rise in NASH correlates with the increasing prevalence of metabolic syndrome.

Purpose of the Study:

  • To review animal models of steatohepatitis.
  • To investigate mechanisms regulating hepatic lipid, glucose, and cholesterol homeostasis in steatotic livers.
  • To understand inflammatory recruitment and fibrogenesis in the steatotic liver.

Main Methods:

  • Review of existing literature on animal models of steatohepatitis.
  • Analysis of studies examining hepatic lipid, glucose, and cholesterol metabolism.
  • Examination of research on inflammatory and fibrotic processes in animal models.

Main Results:

  • Animal models are crucial for dissecting the complex mechanisms of NASH.
  • These models allow for the study of hepatic lipid accumulation, inflammation, and fibrosis.
  • Insights from animal models contribute to understanding the progression of liver disease.

Conclusions:

  • Animal models provide valuable tools for studying NASH pathogenesis.
  • Research in these models aims to elucidate the roles of lipid, inflammation, and fibrosis.
  • The ultimate goal is to gain insights applicable to human non-alcoholic fatty liver disease.
