May 2009 in “Journal of Neuroscience” In this study, researchers found that in late pregnancy, the neuroactive progesterone metabolite allopregnanolone inhibits HPA axis responses to immune challenges via an opioid-mediated mechanism.

April 2004 in “Journal of Neurochemistry” In this study, acute restraint stress increased Y1 receptor gene expression in the amygdala and PVN of transgenic mice, but this effect was not due to elevated neuroactive steroid concentrations, indicating a potential ligand-induced mechanism.

February 2025 in “GeroScience” This study found that restoring hypothalamic NPY levels in mice delayed aging-related characteristics such as fat loss, hair loss, and memory decline, suggesting that maintaining these levels could be important for counteracting aging and its effects.
