The Role of the Gut Microbiome in Nonalcoholic Fatty Liver Disease

Sanjoy Roychowdhury et al. Med Sci (Basel). .

Abstract

Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease, with prevalence increasing in parallel with the rising incidence in obesity. Believed to be a "multiple-hit" disease, several factors contribute to NAFLD initiation and progression. Of these, the gut microbiome is gaining interest as a significant factor in NAFLD prevalence. In this paper, we provide an in-depth review of the progression of NAFLD, discussing the mechanistic modes of hepatocyte injury and the potential role for manipulation of the gut microbiome as a therapeutic strategy in the prevention and treatment of NAFLD.

Keywords: NAFLD; apoptosis; gut microbiome; necroptosis; probiotics.

Hepatic cell death pathway and liver injury in response to high fat diet exposure. A HFD induces multiple cell death mechanisms including both caspase-dependent apoptosis and RIP3-driven necroptosis in the liver. Inhibition of RIP3 exacerbates hepatocyte apoptosis following exposure to a HFD, and thus aggravates liver injury and inflammation. A high-fat diet also induces apoptosis in adipocytes. Adipocyte apoptosis drives monocyte/macrophage infiltration, as well as impairs glucose homeostasis. Reprinted with permission, Cleveland Clinic Center for Medical Art & Photography © 2015–2018.
