Megjegyzések:	Milk contains a variety of proteins and peptides that possess biological activity. Growth factors, such as growth hormone, insulin-like, epidermal and nerve growth factors are important milk components which may regulate growth and differentiation in various neonatal tissues and also those of the mammary gland itself. We have recently shown that pituitary adenylate cyclase-activating polypeptide (PACAP), an important neuropeptide with neurotrophic actions, is present in the human milk in much higher concentration than in the plasma of lactating women. Investigation of growth factors in the milk of domestic animals is of utmost importance for their nutritional values and agricultural significance. Therefore, the aim of the present study was to determine the presence and concentration of PACAP in the plasma and milk of three ruminant animal species. Furthermore, the presence of PACAP and its specific PAC1 receptor were investigated in the mammary glands. Radioimmunoassay measurements revealed that PACAP was present in the plasma and the milk of the sheep, goat and the cow in a similar concentration to that measured previously in humans. PACAP38-like immunoreactivity (PACAP38-LI) was 5-20-fold higher in the milk than in the plasma samples of the respective animals, a similar serum/milk ratio was found in all the three species. The levels did not show significant changes within the examined 3-month-period of lactation after delivery. Similar PACAP38-LI was measured in the homogenates of the sheep mammary gland samples taken 7 and 30 days after delivery. PAC1 receptor expression was detected in these udder biopsies by fluorescent immunohistochemistry suggesting that this peptide might have an effect on the mammary glands themselves. These data show that PACAP is present in the milk of various ruminant domestic animal species at high concentrations, the physiological implications of which awaits further investigation.

Cím:	Pituitary Adenylate Cyclase-Activating Polypeptide Is Upregulated in Murine Skin Inflammation and Mediates Transient Receptor Potential Vanilloid-1-Induced Neurogenic Edema / Zsuzsanna Helyes, Jozsef Kun, Nora Dobrosi, Katalin Sándor, Jozsef Németh, Aniko Perkecz, Erika Pintér, Krisztina Szabadfi, Balazs Gaszner, Valeria Tékus, Janos Szolcsányi, Martin Steinhoff, Hitoshi Hashimoto, Dora Reglődi, Tamas Bíró

Megjegyzések:	Although pituitary adenylate cyclase-activating polypeptide (PACAP) was described as a key vasoregulator inhuman skin, little is known about its expression in mouse skin. As it is important to investigate PACAP signaling intranslational mouse dermatitis models, we determined its presence, regulation, and role in neurogenic and nonneurogeniccutaneous inflammatory mechanisms. The mRNA of PACAP and its specific receptor PAC1 wasdetected with real-time PCR in several skin regions at comparable levels. PACAP-38-immunoreactivity measuredwith radioimmunoassay was similar in plantar and dorsal paw skin and the ear but significantly smaller in theback skin. PACAP and PAC1 mRNA, as well as PACAP-38 and PAC1 protein expression, significantly increased in theplantar skin after intraplantar administration of capsaicin (50 ?l, 100 ?gml?1), an agonist of the transient receptorpotential vanilloid 1 (TRPV1) receptor, evoking chiefly neurogenic inflammation without inflammatory cellaccumulation. Intraplantar complete Freund's adjuvant (CFA; 50 ?l, 1mgml?1) also increased PACAP/PAC1 mRNAbut not the PACAP peptide. Capsaicin-induced neurogenic paw edema, but not CFA-evoked non-neurogenicswelling, was significantly smaller in PACAP-deficient mice throughout a 24-hour period. To our knowledge, weprovide previously unreported evidence for PACAP and PAC1 expression upregulation during skin inflammation ofdifferent mechanisms and for its pro-inflammatory function in neurogenic edema formation.

Megjegyzések:	Pituitary adenylate cyclase activating polypeptide(PACAP) is a pleiotropic and multifunctional neuropeptidehaving important roles in various physiological processes.Recent trends in PACAP research point to the clinical introductionof PACAP or its analogs/fragments possibly in thenear future. Recently, we have shown the presence ofPACAP in human plasma, milk, placenta, and follicularfluid samples. However, relatively few data are availableon PACAP in human tissues from patients with differentdisorders. The aim of the present study was to determine, byradioimmunoassay, the tissue level of PACAP38-like immunoreactivity(LI) and PACAP27-LI in different primary nonsmallcell lung cancer, colon tumor samples, and in cardiacmuscle samples from patients suffering from ischemic heartdisease and valvular disorders. We also labeled the PAC1receptors in human cardiac cells. All samples showed significantlyhigher PACAP38-LI compared with PACAP27-LI. We found significantly lower levels of PACAP38-LI andPACAP27-LI in tumoral and peripheral samples comparedwith normal healthy tissue in both lung and colon cancers.Further investigations are necessary to describe the exactfunction of PACAP in oncogenesis. We showed thatPACAP38-LI and PACAP27-LI are significantly higher inischemic heart diseases compared with valvular abnormalities,suggesting that PACAP might play a role in ischemicheart disorders.
