Because of their physiological characteristics, scorpions can be considered laboratory animals in the study of specific problems not only medical (envenomings) but also pharmaco-toxicologic or environmental (resistance to environmental stresses such as radioresistance, or resistance to bacterial infections, epidemiology). Indeed, the scorpion lifetime is long, several years for the larger species, and their breeding is easy. These aspects will be reflected in a series of articles sorted by specialties which provide the widest vision on problems that can be approached using this model. The following topics will shed light on the offered interest research on scorpions:
(i) venoms: in the family Buthidæ, the most important in number (40% species) and the medically most important, the venom composition is usually simple, poor in enzymes. The venom toxins essentially act on membrane ionic channels of excitable cells (neuromuscular system) and their structure is based on a basic model also present in the defensins. The study of toxins acting on sodium channels have led to the discovery of two specific binding sites and require a study of potassium and sodium membrane receptors as well as a comparative study with defensins.
(ii) these toxins involve also inflammatory systemic reactions of great medical interest: release of cytokins and neuromediators, transient myocardial injury, hypertension.
(iii) from a public health point of view, epidemiology is an important issue, as the large majority of the target of severe or lethal poisonings is constituted children and young adolescents. There is also an urban scorpionism of an unusual type in venomous animals, as some dangerous scorpion species are parthenogenetic (genus Tityus, South America). Besides, the value of the serotherapy which developed largely after the antiophidian serotherapy is currently challenged and deserves a specific focus. The possibility of producing efficient recombinant antibodies with a high neutralizing power is more advanced for scorpions than other venomous animals.
With its content this Special Issue involving a wide range of specialists is aimed at the wider public.
