Nonalcoholic steatohepatitis (NASH) is a subtype of nonalcoholic fatty liver disease that is characterised by steatosis, chronic inflammation, and hepatocellular injury with or without fibrosis. The role and activation of macrophages in the pathogenesis of NASH is complex and is being studied for possible therapeutic options to help the millions of people diagnosed with the disease. The purpose of this review is to discuss the pathogenesis of NASH through the activation and role of Kupffer cells and other macrophages in causing inflammation and progression of NASH. Furthermore, this review aims to outline some of the current therapeutic options targeting the pathogenesis of NASH.

Objectives: Non-alcoholic fatty Liver Disease (NAFLD) poses a growing global health concern, yet its complex aetiology remains incompletely understood. Emerging evidence implicates the gut microbiome and choline metabolism in NAFLD pathogenesis. This study aims to elucidate the association of choline-consuming bacteria in gut microbiome with choline level.

Nonalcoholic fatty liver disease (NAFLD) encompasses a spectrum of liver conditions, ranging from hepatic steatosis to steatohepatitis, fibrosis, and severe outcomes such as cirrhosis or cancer. The progression from hepatic steatosis to fibrosis involves significant extracellular matrix (ECM) remodeling, characterized by increased collagen deposition and cross-linking of ECM proteins, causing increased tissue stiffness and altered MMP expression patterns. Dysregulated MMP expression and extracellular acidosis are key contributors to NAFLD progression.

Background: Insulin resistance and the G allele of rs738409 interact to create a greater risk of metabolic dysfunction-associated steatotic liver disease.
Objective: This study aims to confirm that one promising way to reduce insulin resistance is by following a very low-carbohydrate (VLC) dietary pattern.
Methods: Adults with rs738409-GG or -CG with liver steatosis and elevated liver function tests, were taught an ad libitum VLC diet, positive affect and mindful eating skills, goal setting, and self-monitoring and given feedback and coaching for 4 months.

Reactive oxygen species exacerbate nonalcoholic steatohepatitis (NASH) by oxidizing macromolecules; yet how they promote NASH remains poorly understood. Here, we show that peroxidase activity of global hepatic peroxiredoxin (PRDX) is significantly decreased in NASH, and palmitic acid (PA) binds to PRDX1 and inhibits its peroxidase activity. Using three genetic models, we demonstrate that hepatic PRDX1 protects against NASH in male mice.

Purpose Of Review: This narrative review explores the role of Medical Nutritional Therapy (MNT) in managing Metabolic-Associated Steatotic Liver Disease (MASLD), previously known as nonalcoholic fatty liver disease. It aims to examine the effectiveness of specific nutritional strategies in preventing and treating this obesity-linked liver disease.
Recent Findings: Emerging evidence underscores the benefits of the Mediterranean diet, low-carbohydrate diets, and intermittent fasting in reducing liver fat, improving insulin sensitivity, and mitigating inflammation.
