Intravenous administration of the 5-HT1B agonist, m-chlorophenylpiperazine (m-CPP) to rats produced increases in plasma prolactin (peak effect at 15 min), corticosterone (peak effect at 30 min) and a decrease in plasma growth hormone (peak effect at 15 min) concentrations. Short-term or long-term clorgyline treatment did not affect baseline levels of prolactin, corticosterone or growth hormone. Short-term clorgyline treatment attenuated m-CPP's effect on corticosterone but not on prolactin or growth hormone. On the other hand, long-term clorgyline treatment attenuated m-CPP's effect on prolactin but not on corticosterone or growth hormone. These findings are compatible with development of functional subsensitivity of 5-HT1B receptors mediating prolactin release following long-term clorgyline treatment. Attenuation of m-CPP's effect on corticosterone following short-term clorgyline treatment suggests either early adaptational changes in a 5-HT receptor subtype mediating corticosterone release, or clorgyline-induced increases in other neurotransmitters such as norepinephrine which may be responsible for attenuating m-CPP's effect on corticosterone.

D010879	Piperazines	Compounds that are derived from PIPERAZINE.
D011388	Prolactin	A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.
