Presence of prolactin mRNA in extra-pituitary brain areas in the domestic turkey

It is well known that prolactin plays diverse roles in vertebrate reproduction. Besides expression in the pituitary, prolactin is also found in extra-pituitary tissues. In the present study, prolactin mRNA expression was studied utilizing in situ hybridization histochemistry. Prolactin mRNA, while found throughout the turkey brain, was predominantly localized within the pituitary, confirming a pivotal role of prolactin in turkey reproduction. The expression of prolactin mRNA was also observed within extra-pituitary brain areas including the cerebellum, nucleus accumbens, lateral septum, anterior hypothalamic nucleus, lateral hypothalamus, paraventricular nucleus, ventromedial nucleus, and infundibular nuclear complex. In the hypothalamus, an abundance of prolactin mRNA-expressing cells was observed in the anterior hypothalamic nucleus, lateral hypothalamus, and ventromedial nucleus. Cells expressing the least prolactin mRNA were found in the lateral septum, paraventricular nucleus, and the infundibular nuclear complex. This study reveals, for the first time, that prolactin mRNA was expressed in extra-pituitary brain areas in birds. In addition, the diverse expression of prolactin mRNA in the brain areas suggests that prolactin plays various physiological roles in birds.     

Cervical stimulation activates A1 and locus coeruleus neurons that project to the paraventricular nucleus of the hypothalamus

In female rats, stimulation of the uterine cervix during mating induces two daily surges of prolactin. Inhibition of hypothalamic dopamine release and stimulation of oxytocin neurons in the paraventricular nucleus (PVN) are required for prolactin secretion. We aim to better understand how stimulation of the uterine cervix is translated into two daily prolactin surges. We hypothesize that noradrenergic neurons in the A1, A2, and locus coeruleus (LC) are responsible for conveying the peripheral stimulus to the PVN. In order to determine whether projections from these neurons to the PVN are activated by cervical stimulation (CS), we injected a retrograde tracer, Fluoro-Gold (FG), into the PVN of ovariectomized rats. Fourteen days after injection, animals were submitted to artificial CS or handling and perfused with a fixative solution. Brains were removed and sectioned from the A1, A2, and LC for c-Fos, tyrosine hydroxylase (TH), and FG triple-labeling using immunohistochemistry. CS increased the percentage of TH/FG+ double-labeled neurons expressing c-Fos in the A1 and LC. CS also increased the percentage of TH+ neurons expressing c-Fos within the A1 and A2, independent of their projections to the PVN. Our data reinforce the significant contributions of the A1 and A2 to carry sensory information during mating, and provide evidence of a functional pathway in which CS activates A1 and LC neurons projecting to the PVN, which is potentially involved in the translation of CS into two daily prolactin surges.
