Because of its characteristics, this infection is used as an animal model for acute liver failure (ALF). Apoptosis is one of the key processes underlying ALF and has been described as one of the mechanisms of RHD pathogenesis. Apoptotic cell death has been quite well characterized in infection with different variants of GI.1 strains, but so far, the GI.2 genotype has not been widely studied. In this study, we performed an evaluation of apoptotic cell death in hepatocytes of rabbits infected with Lagovirus europaeus\/GI.2. We analyzed the expression of genes involved in apoptotic cell death by real-time PCR and performed immunohistochemical (IHC) assays. We showed a significant increase in the expression of caspase-3 and the proapoptotic Bax and anti-apoptotic Bcl-2 in infected animals. In addition, we recorded increased Bax\/Bcl-2 ratios. IHC analyses showed the presence of morphological signs of apoptosis in the hepatocytes of infected rabbits. Our results indicate that caspase-3 and proteins from the Bcl-2 families play a key role in apoptosis induced by Lagovirus europaeus\/GI.2 infection.<\/jats:p>","DOI":"10.3390\/ijms25020798","type":"journal-article","created":{"date-parts":[[2024,1,9]],"date-time":"2024-01-09T04:38:51Z","timestamp":1704775131000},"page":"798","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Apoptotic Cell Death in an Animal Model of Virus-Induced Acute Liver Failure\u2014Observations during Lagovirus europaeus\/GI.2 Infection"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3689-2381","authenticated-orcid":false,"given":"Dominika","family":"B\u0119bnowska","sequence":"first","affiliation":[{"name":"Institute of Biology, University of Szczecin, Felczaka 3c, 71-412 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0688-6928","authenticated-orcid":false,"given":"Rafa\u0142","family":"Hrynkiewicz","sequence":"additional","affiliation":[{"name":"Institute of Biology, University of Szczecin, Felczaka 3c, 71-412 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2157-0315","authenticated-orcid":false,"given":"Sylwia","family":"Rzeszotek","sequence":"additional","affiliation":[{"name":"Department of Histology and Embryology, Faculty of Medicine and Dentistry, Pomeranian Medical University in Szczecin, Powsta\u0144c\u00f3w Wlkp. 72, 70-111 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marika","family":"Freus","sequence":"additional","affiliation":[{"name":"Department of Histology and Embryology, Faculty of Medicine and Dentistry, Pomeranian Medical University in Szczecin, Powsta\u0144c\u00f3w Wlkp. 72, 70-111 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6719-803X","authenticated-orcid":false,"given":"Agata","family":"Poniewierska-Baran","sequence":"additional","affiliation":[{"name":"Institute of Biology, University of Szczecin, Felczaka 3c, 71-412 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4065-3842","authenticated-orcid":false,"given":"Paulina","family":"Nied\u017awiedzka-Rystwej","sequence":"additional","affiliation":[{"name":"Institute of Biology, University of Szczecin, Felczaka 3c, 71-412 Szczecin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"B\u0119bnowska, D., and Nied\u017awiedzka-Rystwej, P.
