The aim of the study was to determine how acrylamide affects the pituitary adenylate cyclase-activating polypeptide (PACAP)-immunoreactive intramural neurons in the small intestine of sexually immature gilts. Methods: The study was conducted on 15 sexually immature Danish gilts receiving for 28 days empty gelatin capsules or acrylamide in low (0.5 \u00b5g\/kg of body weight (b.w.)\/day) and high (5 \u00b5g\/kg b.w.\/day) doses. After euthanasia, intestinal sections were stained using the double immunofluorescence staining procedure. Results: Studies have shown that oral administration of acrylamide in both doses induced a response of intramural neurons expressed as an increase in the population of PACAP-immunoreactive neurons in the small intestine. In the duodenum, only in the myenteric plexus (MP) was an increase in the number of PACAP-immunoreactive (IR) neurons observed in both experimental groups, while in the outer submucous plexus (OSP) and inner submucous plexus (ISP), an increase was noted only in the high-dose group. In the jejunum, both doses of acrylamide led to an increase in the population of PACAP-IR neurons in each enteric plexus (MP, OSP, ISP), while in the ileum, only supplementation with the higher dose of acrylamide increased the number of PACAP-IR enteric neurons in the MP, OSP, and ISP. Conclusions: The obtained results suggest the participation of PACAP in acrylamide-induced plasticity of enteric neurons, which may be an important line of defence from the harmful action of acrylamide on the small intestines.<\/jats:p>","DOI":"10.3390\/ijerph20043272","type":"journal-article","created":{"date-parts":[[2023,2,13]],"date-time":"2023-02-13T05:25:26Z","timestamp":1676265926000},"page":"3272","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Acrylamide-Induced Changes in the Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP) Immunoreactivity in Small Intestinal Intramural Neurons in Pigs"],"prefix":"10.3390","volume":"20","author":[{"given":"Aleksandra","family":"Karpiesiuk","sequence":"first","affiliation":[{"name":"Department of Clinical Physiology, Faculty of Veterinary Medicine, University of Warmia and Mazury in Olsztyn, Oczapowskiego Str. 13, 10-718 Olsztyn, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaros\u0142aw","family":"Ca\u0142ka","sequence":"additional","affiliation":[{"name":"Department of Clinical Physiology, Faculty of Veterinary Medicine, University of Warmia and Mazury in Olsztyn, Oczapowskiego Str. 13, 10-718 Olsztyn, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7593-9552","authenticated-orcid":false,"given":"Katarzyna","family":"Palus","sequence":"additional","affiliation":[{"name":"Department of Clinical Physiology, Faculty of Veterinary Medicine, University of Warmia and Mazury in Olsztyn, Oczapowskiego Str. 13, 10-718 Olsztyn, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,13]]},"reference":[{"key":"ref_1","first-page":"6","article-title":"Acrylamide an in vitro thyroid carcinogenic agent, induces DNA damage in rat thyroid cell lines and primary cultures","volume":"257\u2013258","author":"Massart","year":"2006","journal-title":"Mol.
