Abstract
The liver fluke Opisthorchis felineus is a foodborne zoonotic pathogen endemic to Russia, Kazakhstan, and several European countries. The adult flukes affect the hepatobiliary system of piscivorous mammals and humans, thereby causing numerous complications, including liver fibrosis. Detailing the mechanisms of progression of the fibrotic complications is a hot topic in the field of research on opisthorchiasis pathogenesis. Pathologic angiogenesis appears to be associated with the fibrogenic progression due to active participation in the recruitment of inflammatory cells and many factors involved in the modulation of the extracellular matrix. The aim of the study was to evaluate neoangiogenesis and amyloid deposits in liver tissues of model animals and patients with confirmed chronic opisthorchiasis. In addition, we assessed a possible correlation of neoangiogenesis with liver fibrosis. We found a significant increase in the number of newly formed vessels and amyloid deposits in the liver of people with chronic opisthorchiasis compared to that of uninfected ones. Thus, for the first time we have demonstrated neoangiogenesis and amyloid deposits during O. felineus infection in a Mesocricetus auratus model. Regression analysis showed that CD34+ newly formed vessels correlate with fibrosis severity in the course of the infection. Our results indicate the potential contribution of angiogenesis to the progression of liver fibrosis, associated with O. felineus infection.

Extracellular vesicles of the liver fluke Opisthorchis felineus stimulate the angiogenesis of human umbilical vein endothelial cells. CURRENT RESEARCH IN PARASITOLOGY & VECTOR-BORNE DISEASES 2023; 4:100153. [PMID: 38045538 PMCID: PMC10690567 DOI: 10.1016/j.crpvbd.2023.100153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 10/05/2023] [Accepted: 10/26/2023] [Indexed: 12/05/2023]
Abstract
The liver fluke Opisthorchis felineus is a clinically important food-borne parasite of humans. Infection with O. felineus in mammals is associated with liver morbidities such as periductal fibrosis, bile duct neoplasia, and chronic inflammation. Previously we have shown that excretory-secretory products (ESP) can stimulate the healing of skin wounds in mice, which may be due to stimulated angiogenesis and extracellular matrix remodeling. However, there are no studies analyzing the angiogenic character of O. felineus, and its effects on angiogenesis, vascularity, and vascular endothelium. The aim of this study was to evaluate the capacity of ESP and extracellular vesicles (EVs) of O. felineus to stimulate angiogenesis and the formation of pseudo-capillaries in vitro. We also aimed at the assessment of the angiogenesis during the infection in vivo, and estimation of the endothelial cell type abundances from heterogeneous bulk liver transcriptome between uninfected and infected animals with single-cell information. The study revealed significant alterations in vascularity in the hamster liver and significant involvement of portal endothelial cells at the transcriptome level. We also demonstrated that the ESP and EVs of O. felineus have the capacity to stimulate the formation of pseudo-capillaries in vitro. Both ESP and EVs appeared to have similar effects on all four parameters, increasing node formation and total master segments length, and significantly decreasing total isolated branches length and number of isolated segments of pseudo-capillaries. The liver flukes manipulate the host's angiogenic response, a fact that has been related to the pathogenesis caused by these parasites. Understanding these pathogenic mechanisms may uncover new therapeutic targets to relieve or prevent the most severe complications of opisthorchiasis.
