Randomized trial evaluates IL-1β's effects on hepatic metabolism, indicating its role in lipid accumulation.

This study aims to investigate the effects of IL-1β on hepatic metabolism, focusing on its insulin-independent actions.
Fasting wild-type and hepatocyte-specific IL-1 receptor knockout mice received IL-1β.
Primary hepatocytes from both mouse types were stimulated with IL-1β to assess glucose production and gene expression.
In vitro analyses included measuring gluconeogenesis and lipid synthesis pathways in hepatocytes.
Pre-treatment with IL-1β led to sustained hypoglycemia and suppressed hepatic glucose production, despite normalized insulin levels.
IL-1β induced triglyceride accumulation in the liver and altered metabolism towards glycolysis.
In vitro, IL-1β inhibited glucagon-stimulated gluconeogenesis, redirecting hepatocyte metabolism to lipid synthesis.

NEUBERT et al. (2026) studied this question.
