摘要

杆状细胞是一种独特的梨形细胞，主要存在于远洋鱼类的上皮细胞中。1892 年，Thèlohan 首次发现了小杆细胞，并将其命名为 Rhabdospora thelohani，因为人们认为它是原生动物门的一种寄生虫。此后，小杆孢子细胞作为寄生虫的说法持续了几十年，但在过去 20 多年中逐渐消失。现在，人们普遍认为小杆细胞是一种免疫细胞，对寄生虫的入侵起着早期反应的作用。这篇简短的综述详细比较了 apicomplexan 与小杆细胞的结构和行为，以进一步加强对鱼类细胞寄生性质的论证。然后提出，小杆细胞顶端的微绒毛可作为小杆排出的机械触发器，以抵御较大的体外寄生虫。

A comparison of teleost rodlet cells with apicomplexan cells

Rodlet cells are unique pear-shaped cells found primarily in the epithelium of the teleost fishes. The rodlet cell was first identified by Thèlohan in 1892 who named it Rhabdospora thelohani as it was believed to be a protozoan parasite of the phylum Apicomplexa. The rodlet cell as parasite paradigm persisted for several decades afterwards but has since faded in the last 20 years or so. The rodlet cell is now generally believed to be an immune cell, functioning as an early responder to parasite intrusion. This short review makes a detailed comparison of apicomplexan structure and behavior with that of the rodlet cell to further strengthen the argument against a parasitic nature for the fish cell. It is then proposed that apical microvilli of the rodlet cell serve as a mechanical trigger for rodlet discharge as possible defense against larger ectoparasites.

期刊介绍： Acta histochemica, a journal of structural biochemistry of cells and tissues, publishes original research articles, short communications, reviews, letters to the editor, meeting reports and abstracts of meetings. The aim of the journal is to provide a forum for the cytochemical and histochemical research community in the life sciences, including cell biology, biotechnology, neurobiology, immunobiology, pathology, pharmacology, botany, zoology and environmental and toxicological research. The journal focuses on new developments in cytochemistry and histochemistry and their applications. Manuscripts reporting on studies of living cells and tissues are particularly welcome. Understanding the complexity of cells and tissues, i.e. their biocomplexity and biodiversity, is a major goal of the journal and reports on this topic are especially encouraged. Original research articles, short communications and reviews that report on new developments in cytochemistry and histochemistry are welcomed, especially when molecular biology is combined with the use of advanced microscopical techniques including image analysis and cytometry. Letters to the editor should comment or interpret previously published articles in the journal to trigger scientific discussions. Meeting reports are considered to be very important publications in the journal because they are excellent opportunities to present state-of-the-art overviews of fields in research where the developments are fast and hard to follow. Authors of meeting reports should consult the editors before writing a report. The editorial policy of the editors and the editorial board is rapid publication. Once a manuscript is received by one of the editors, an editorial decision about acceptance, revision or rejection will be taken within a month. It is the aim of the publishers to have a manuscript published within three months after the manuscript has been accepted
