Story summary

Researchers have identified a nuclear role for hormone-sensitive lipase (HSL) in fat cells that helps maintain healthy adipose tissue.
Adrenaline regulates HSL levels in the nucleus and activates HSL on lipid droplets.
The discovery explains why individuals lacking HSL develop lipodystrophy instead of obesity.
The findings are relevant as obesity affects half of adults in France and poses global health risks.
