Abstract

The skin of snakes acts as the first interface between these reptiles and the environment they live in. It plays an important role in the ecology of these organisms, and specialised structures, such as tactile corpuscles, are crucial in the sensing of a wide variety of stimuli. This study, by examining the presence, localisation and colocalisation of serotonin, substance P, PGP 9.5 and tubulin, wants to demonstrate the sensory role that these structures play in the ecology of the Green whip snake Hierophis viridiflavus (Lacépède, 1789). This study presents the first evaluation of nerve and immune molecules (TLR2) in the tactile corpuscles of H. viridiflavius ventral skin, indicating a potential defence role of these structures. These findings provide valuable information on the ecology of snakes, their defence systems, and their evolutionary morphostructural adaptations. Additionally, the identification of these corpuscles could provide valuable support for taxonomic recognition. Furthermore, this study expands the knowledge about stimuli sensing in snakes.

蛇皮的进化:viridiflavus 蛇(Lacépède,1789 年)皮肤触觉细胞的作用
蛇类的皮肤是这些爬行动物与生活环境之间的第一个界面。皮肤在这些生物的生态学中扮演着重要角色,而触觉体等特殊结构则是感知各种刺激的关键。本研究通过检测血清素、P 物质、PGP 9.5 和微管蛋白的存在、定位和共定位,希望证明这些结构在绿鞭蛇(Hierophis viridiflavus,Lacépède,1789 年)的生态学中发挥的感官作用。本研究首次评估了绿鞭蛇腹部皮肤触觉团中的神经和免疫分子(TLR2),表明这些结构具有潜在的防御作用。这些发现为蛇的生态学、防御系统及其进化形态-结构适应性提供了宝贵的信息。此外,对这些冠状体的鉴定可为分类识别提供有价值的支持。此外,这项研究还扩展了有关蛇类刺激感应的知识。

期刊介绍: Published regularly since 1920, Acta Zoologica has retained its position as one of the world''s leading journals in the field of animal organization, development, structure and function. Each issue publishes original research of interest to zoologists and physiologists worldwide, in the field of animal structure (from the cellular to the organismic level) and development with emphasis on functional, comparative and phylogenetic aspects. Occasional review articles are also published, as well as book reviews.
