Non-alcoholic
Fatty Liver
Disease (NAFLD) is the most common form of liver disease and is associated with metabolic dysregulation. Although
G protein-coupled receptor 84
(
GPR84
) has been associated with inflammation, its role in metabolic regulation remains elusive. The aim of our study was to evaluate the potential of PBI-4547 for the treatment of NAFLD and to validate the role of its main target receptor,
GPR84
. We report that PBI-4547 is a fatty acid mimetic, acting concomitantly as a
GPR84
antagonist and GPR40/GPR120 agonist. In a mouse model of diet-induced obesity, PBI-4547 treatment improved metabolic dysregulation, reduced
hepatic steatosis
, ballooning and NAFLD score. PBI-4547 stimulated fatty acid oxidation and induced gene expression of mitochondrial uncoupling proteins in the liver. Liver metabolomics revealed that PBI-4547 improved metabolic dysregulation induced by a high-fat diet regimen. In Gpr84
-/-
mice, PBI-4547 treatment failed to improve various key NAFLD-associated parameters, as was observed in wildtype littermates. Taken together, these results highlight a detrimental role for the
GPR84
receptor in the context of meta-inflammation and suggest that
GPR84
antagonism via PBI-4547 may reflect a novel treatment approach for NAFLD and its related complications.
