Abstract

We found two functional populations of hemocytes in the hemolymph of the pulmonate snail Planorbarius corneus: hyalinocytes and granulocytes. The hyalinocytes were much more numerous than granulocytes. Each population was subdivided into subpopulations based on morphological and functional characteristics. The hyalinocyte population was represented by two subpopulations differing in size, granularity, and ability to form pseudopodia. In snails infected with the trematodes Plagiorchis sp., the cellular composition of the hemolymph changes, with hemocytes being mostly represented by granulocytes. This phenomenon is associated with the fact that granulocytes form a hemocytic paletot on the surface of sporocysts of Plagiorchis sp. It is suggested that pulmonate molluscs have one lineage of hemolymph cells. Hematopoietic stem cells can divide, ensuring multiplication of prohemocytes. The latter differentiate into hyalinocytes, which, in turn, differentiate into granulocytes.

感染吸虫Plagiochis sp.后蜗牛血淋巴细胞组成的变化。

我们在肺螺的血淋巴中发现了两个功能性的血细胞群:透明细胞和粒细胞。透明细胞比粒细胞多得多。每个种群根据形态和功能特征再划分为亚种群。透明细胞群由两个亚群代表，在大小、粒度和形成假足的能力上不同。钉螺感染斜吸虫后，其血淋巴的细胞组成发生变化，血细胞主要以粒细胞为代表。这一现象与粒淋巴细胞在斜鳃软体动物的孢子囊表面形成血细胞盘有关，提示肺源性软体动物具有单一的血淋巴细胞谱系。造血干细胞可以分裂，保证了造血原细胞的增殖。后者分化为透明质细胞，而透明质细胞又分化为粒细胞。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
