Research Abstract

Lysophosphatidic acid(LPA) is a bioactive lipid mediator eliciting diverse biological functions though its specific G protein-coupled receptors. Although we have identified the fourth LPA receptor LPA4, little is known about physiological or pathological role of LPA4. Here we have revealed that LPA4 is involved in obesity-associated insulin resistance and fatty liver by using LPA4-deficient mice.
