The neuropeptide calcitonin gene-related peptide (CGRP) mediates inflammation and head pain by influencing the functional vascular blood supply. CGRP is a well-characterized mediator of receptor-regulated neurotransmitter release. However, knowledge regarding the role of CGRP during the development of the superior cervical ganglion (SCG) is limited. In the present study, we observed the localization of CGRP and vascular endothelial growth factor (VEGF-A) mRNAs during prenatal development at embryonic day 14.5 (E14.5), E17.5 and postnatal day 1 (P1) using in situ hybridization. The antisense probe for CGRP was detected by in situ hybridization at E14.5, E17.5, and P1, and the highest levels were detected at E17.5. In contrast, the antisense probe for VEGF-A was detected by in situ hybridization in gradually increasing intensity from E14.5 to P1. The differences in the expression of these two markers revealed specific characteristics related to CGRP concentration and release compared to those of VEGF-A during development. The correlation between CGRP and VEGF-A may influence functional stress and the vascular blood supply during prenatal and postnatal development.

Pituitary Adenylate Cyclase

Vasoactive intestinal polypeptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP) are regulatory neuropeptides of the hypothalamus–hypophyseal–adrenal axis, acting via the common receptors VPAC1 and VPAC2 and the selective PACAP receptor PAC1. In the adrenal glands of the Italian wall lizard, Podarcis sicula, the presence of VIP in chromaffin cells, and the VIP-stimulated release of catecholamine and aldosterone in vivo, was previously shown. To examine the localization of both peptides and receptors and their mRNAs in the adrenal gland of P. sicula, immunohistochemistry and in situ hybridization were performed: PACAP and its mRNA were detected in chromaffin cells, VPAC1 was found associated with steroidogenic tissue, VPAC2 and PAC1 with chromaffin tissue. Using ‘far western blot’ technique, we showed the presence of specific binding sites for VIP/PACAP in the adrenal glands of the lizard. The effects of both VIP and PACAP on the adrenal cells of the lizard were examined in vitro in adrenal cell co-cultures: both VIP and PACAP enhanced catecholamine, corticosterone and aldosterone release from adrenal cell co-culture in a time- and dose-dependent manner. The catecholamine release was inhibited by PAC1 antagonist and in VPAC2 immunoneutralized adrenal cells. The effects of VIP and PACAP on aldosterone secretion were counteracted by VPAC1 antagonist administration in vitro. Corticosterone secretion elicited by VIP was not blocked by VPAC1 antagonist, while the PACAP-induced release of corticosterone was blocked by the antagonist. Overall, our investigations indicate that these neuropeptides of the secretin superfamily can act not only as neurotransmitters but also as autocrine and paracrine regulators on chromaffin and cortical cells, being important mediators of the non-cholinergic system in the lizard adrenal gland.
