The experiment was performed using 40 male Wistar rats fed a typical rat diet with two dosages of Cu used as CuCO3 (6.5 and 13 mg\/kg diet) and dietary addition of two CuNP dosages (standard 6.5 and enhanced 13 mg\/kg diet), randomly divided into four groups. The levels of neurodegenerative markers were evaluated. Nanoparticles caused a reduction in the level of glycosylated acetylcholinesterase (GAChE), an increase the level of acetylcholinesterase (AChE) and lipoprotein receptor-related protein 1 (LRP1), a reduction in \u03b2-amyloid (\u03b2AP) in the brain and in the intestine of rats and a reduction in Tau protein in the brain of rats. The highest levels of AChE, the ATP-binding cassette transporters (ABC) and LRP1 and lower levels of toxic GAChE, \u03b2-amyloid, Tau, hyper-phosphorylated Tau protein (p-Tau) and the complex of calmodulin and Ca2+ (CAMK2a) were recorded in the tissues of rats receiving a standard dose of Cu. The neuroprotective effect of Cu can be increased by replacing the carbonate form with nanoparticles and there is no need to increase the dose of copper.<\/jats:p>","DOI":"10.3390\/ijms241411321","type":"journal-article","created":{"date-parts":[[2023,7,12]],"date-time":"2023-07-12T00:50:41Z","timestamp":1689123041000},"page":"11321","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["The Influence of Copper Nanoparticles on Neurometabolism Marker Levels in the Brain and Intestine in a Rat Model"],"prefix":"10.3390","volume":"24","author":[{"given":"Monika","family":"Cendrowska-Pinkosz","sequence":"first","affiliation":[{"name":"Chair and Department of Human Anatomy, Medical University of Lublin, 20-090 Lublin, Poland"},{"name":"CM Alergologia, 20-865 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4287-4665","authenticated-orcid":false,"given":"Magdalena","family":"Krauze","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Toxicology, Faculty of Animal Science and Bioeconomy, University of Life Sciences in Lublin, 20-950 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0068-5970","authenticated-orcid":false,"given":"Jerzy","family":"Ju\u015bkiewicz","sequence":"additional","affiliation":[{"name":"Department of Biological Functions of Food, Division of Food Science, Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences, 10-748 Olsztyn, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9727-7481","authenticated-orcid":false,"given":"Bartosz","family":"Fotschki","sequence":"additional","affiliation":[{"name":"Department of Biological Functions of Food, Division of Food Science, Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences, 10-748 Olsztyn, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katarzyna","family":"Ognik","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Toxicology, Faculty of Animal Science and Bioeconomy, University of Life Sciences in Lublin, 20-950 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Cendrowska-Pinkosz, M., Ostrowska-Lesko, M., Ognik, K., Krauze, M., Ju\u015bkiewicz, J., D\u0105browska, A., Szponar, J., and Mandziuk, S.
