AgRP neurons in the brain are activated by fasting. The images show immunostaining of neurons from mice that fast for four hours (right) and mice that do not fast (left). Stained are AgRP neurons (Cyan), POMC neurons (Yellow) and a marker for synaptic activity (cFOS, Magenta).
The brain releases the hormone corticosterone after short fasting that boosts autophagy. AgRP neurons in the brain are activated by fasting. The images show immunostaining of neurons from mice that fast for four hours ( right ) and mice that do not fast ( left ). Stained are AgRP neurons ( Cyan ), POMC neurons ( Yellow ) and a marker for synaptic activity (cFOS, Magenta ). Weiyi Chen/ Max Planck Institute for Metabolism Research - Fasting triggers autophagy in our body. The body switches on the waste disposal system in the cells and gains new energy. Researchers at the Max Planck Institute for Metabolism Research in Cologne have now shown in mice that the brain plays a decisive role in this process.
