Abstract

Liver fluke infection is a major risk for cholangiocarcinoma (CCA). It has been established that the Asian liver flukes, Clonorchis sinensis and Opisthorchis viverrini secrete growth factors, digestive enzymes, and extracellular vesicles (EVs) which contribute to abnormal cell development in the bile ducts where the worms reside. These secretions - combined with aberrant inflammation and repeated cycles of chronic wounding at the site of parasite attachment and grazing on the epithelium - promote biliary hyperplasia and fibrosis and ultimately malignant transformation. Application of post-genomic and gene-editing tools to the study of liver fluke immunobiology and pathogenesis has accelerated the discovery of essential virulence factors to which targeted therapies and diagnostics can be directed.

肝吸虫诱发胆管癌的机理研究。
肝吸虫感染是胆管癌(CCA)的一个主要风险因素。目前已经证实,亚洲肝吸虫、中华肝吸虫(Clonorchis sinensis)和肝吸虫(Opisthorchis viverrini)会分泌生长因子、消化酶和细胞外囊泡(EVs),导致虫体所在胆管中的细胞发育异常。这些分泌物与异常炎症、寄生虫附着部位的慢性伤害和上皮细胞上的反复循环相结合,促进了胆管增生和纤维化,并最终导致恶性转化。将后基因组学和基因编辑工具应用于肝吸虫免疫生物学和致病机理的研究,加快了重要毒力因子的发现,从而可以针对这些毒力因子进行靶向治疗和诊断。

期刊介绍: Since its inception as Parasitology Today in 1985, Trends in Parasitology has evolved into a highly esteemed review journal of global significance, reflecting the importance of medical and veterinary parasites worldwide. The journal serves as a hub for communication among researchers across all disciplines of parasitology, encompassing endoparasites, ectoparasites, transmission vectors, and susceptible hosts. Each monthly issue of Trends in Parasitology offers authoritative, cutting-edge, and yet accessible review articles, providing a balanced and comprehensive overview, along with opinion pieces offering personal and novel perspectives. Additionally, the journal publishes a variety of short articles designed to inform and stimulate thoughts in a lively and widely-accessible manner. These include Science & Society (discussing the interface between parasitology and the general public), Spotlight (highlighting recently published research articles), Forum (presenting single-point hypotheses), Parasite/Vector of the Month (featuring a modular display of the selected species), Letter (providing responses to recent articles in Trends in Parasitology), and Trendstalk (conducting interviews). Please note that the journal exclusively publishes literature reviews based on published data, with systematic reviews, meta-analysis, and unpublished primary research falling outside our scope.
