Sample
N=N/A (multiple rat cohorts)
Participants
Sprague-Dawley female rats exposed to single prolonged stress (SPS) PTSD model

What This Study Found

Female rats needed 1,200 μg intranasal NPY (4x male dose) to prevent SPS-induced depression. Combining 600 μg NPY + DPP4 inhibitor was equally effective.

Key Numbers

1,200 μg effective (4x male 300 μg); 600 μg alone ineffective; 600 μg + omarigliptin effective; prevented FST depression; tested at 19 days post-SPS

How They Did This

Sprague-Dawley female rats. SPS model. Multiple NPY doses tested intranasally after SPS. Behavioral testing at 19 days: forced swim, elevated plus maze, social interaction. DPP4 inhibitor combination tested.

Why This Research Matters

PTSD and depression disproportionately affect women. Understanding sex-specific dosing of neuropeptide therapies is essential for effective treatment.

What This Study Doesn't Tell Us

Rat model. SPS may not fully replicate human PTSD. Only one behavioral timepoint tested. Intranasal delivery in rats differs from humans.
