Lipid droplets in mouse liver (IMAGE) Cold Spring Harbor Laboratory Caption When the neurons Li studied were inactivated, it protected mice against long-term weight gain. The left image shows lipid droplets (red) in the liver of a mouse that had those neurons turned off. In contrast, the right image shows many more lipid droplets in mice that did not have the neurons turned off.
