AdipoRon (AR) inhibits methamphetamine (MA) reward memories by targeting the BLA-PrL circuit. This pathway, involving AdipoR1 and p-AMPK/Cav1.3 signaling, offers a potential therapeutic target for MA use disorders.
Area of Science:
- Neuroscience
- Molecular Biology
- Pharmacology
Background:
- Addiction involves drug-related memories and environmental cues.
- Neural mechanisms of methamphetamine (MA) memory are not fully understood.
Purpose of the Study:
- Investigate AdipoRon's effect on MA-induced memory formation.
- Elucidate the neural circuits and molecular pathways involved.
Main Methods:
- Used conditioned place preference (CPP) in MA-conditioned mice.
- Examined basolateral amygdala (BLA) CaMKIIα neuron activity.
- Investigated the BLA to prelimbic cortex (PrL) circuit.
Main Results:
- AdipoRon (AR) inhibited MA-induced CPP and BLA CaMKIIα neuron activity.
- Identified a BLA→PrL excitatory circuit for MA reward memory.
- Found AdipoR1, p-AMPK/Cav1.3 signaling in BLA CaMKIIα neurons modulate MA memory, influenced by exercise.
Conclusions:
- AdipoR1 in the BLACaMKIIα→PrLCaMKIIα circuit is crucial for MA memory formation.
- This pathway presents a potential therapeutic target for MA use disorders.

One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral...
