NIH-funded research R15 grant

ApoA4 and sympathetic signals to improve fat metabolism in obesity

Official title: Effects of Apolipoprotein A4 on Lipid Metabolism via Sympathetic Regulation

Funded at Miami University Oxford · NIH-11359236 · Data updated 2026-11-12

A researcher team will study how apolipoprotein A4 (APOA4) affects fat tissue and liver metabolism through the body’s sympathetic nervous system, with a focus on adults with obesity.

Who could benefit from this research

Could help

Ideal candidates are adults with obesity who may benefit from therapies targeting lipid metabolism and sympathetic pathways.

Less likely to help

Individuals without obesity or those not related to lipid metabolism disorders may not benefit from these findings.

What this research studies

This project studies APOA4’s ability to boost sympathetic activity and fatty acid use in fat tissue, potentially lowering harmful fats in the blood. It will test how APOA4 changes fat and liver metabolism in obese mice, examining the roles of norepinephrine and adrenergic receptors. The study uses a two-aim approach to see how APOA4 affects lipid metabolism in adipose tissues and in the liver, and whether these effects depend on sympathetic signaling in both sexes. Findings could uncover new biological targets for therapies aimed at reducing triglycerides and liver fat in obesity.

Why it matters

Potential benefit: If successful, the work could lead to new strategies to lower triglycerides and improve liver and heart health in people with obesity.

How similar studies have gone: Prior studies in animals showed APOA4 can increase fat burning and lower fat mass; this project extends those findings to understand mechanisms.
