disease and is characterized by microglial activation and the secretion of proinflammatory
mediators. We previously reported that a surge in prostaglandin D 2 (PGD 2) production and
PGD 2-induced microglial activation could provoke neuroinflammation. We also reported
that a lipid sensor GPR120 (free fatty acid receptor 4), which is expressed in intestine, could
be activated by polyunsaturated fatty acids (PUFA), thereby mediating secretion of glucagon …
