摘要

我们提供了细胞外囊泡(EVs)分泌在所有寄生阶段的绦虫(Schistocephalus solidus, m ller, 1776)(虫纲:Diphyllobothriidea)的实验室生命周期模型的第一个超微结构证据。我们在所有阶段都证实了evs样体的存在，包括六爪鱼、桡足类的原尾虫、巨眼棘鱼(Jurine, 1820)、三棘棘鱼体腔中的补尾虫、林内棘鱼和人工培养基中培养的成虫。此外，我们还描述了可能参与EV生物发生的新型被膜结构，以及独特的细长EV的存在，类似于先前仅在1758年的林奈肝片吸虫(trematda)、1819年的小膜吸虫(Rudolphi, cestda)和1899年的布鲁氏锥虫(Plimmer et Bradford, Kinetoplastida)中描述的EVs。

Secretion of extracellular vesicles during ontogeny of the tapeworm Schistocephalus solidus.

We provide the first ultrastructural evidence of the secretion of extracellular vesicles (EVs) across all parasitic stages of the tapeworm Schistocephalus solidus (Müller, 1776) (Cestoda: Diphyllobothriidea) using a laboratory life cycle model. We confirmed the presence of EV-like bodies in all stages examined, including the hexacanth, procercoids in the copepod, Macrocyclops albidus (Jurine, 1820), plerocercoids from the body cavity of the three-spined stickleback, Gasterosteus aculeatus Linnaeus, and adults cultivated in artificial medium. In addition, we provide description of novel tegumental structures potentially involved in EV biogenesis and the presence of unique elongated EVs similar to those previously described only in Fasciola hepatica Linnaeus, 1758 (Trematoda), Hymenolepis diminuta (Rudolphi, 1819) (Cestoda), and Trypanosoma brucei Plimmer et Bradford, 1899 (Kinetoplastida).

期刊介绍： FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
