Stress-induced changes in dietary amino acid preferences and 5-HT2A receptor gene expression in acute and chronic stress models

Key Points

• This research investigates how stress affects dietary amino acid preferences and gene expression of the 5-HT2A receptor in the amygdala.
• Real-time PCR was used to evaluate gene expression in the basolateral amygdala of rats under acute and chronic stress models.
• Changes in amino acid preferences were observed in response to stress.
• Altered expression of the 5-HT2A receptor was detected, indicating a possible link to depression pathophysiology.
