Is the Blood-Brain Barrier a Key to Behavior?

Posted by in categories: biotech/medical, neuroscience

Summary: The blood-brain barrier (BBB) in carpenter ants isn’t just a protective boundary, but actively shapes ant behavior.

The BBB produces an enzyme called Juvenile hormone esterase (Jhe) that degrades the Juvenile Hormone (JH3), which promotes foraging behavior. The presence and degradation of JH3 by the BBB helps determine whether an ant becomes a forager or soldier.

Interestingly, similar mechanisms might influence mouse behavior, hinting at broader implications beyond ants.
