  AaTs-1, a Tetrapeptide from Scorpion Venom Mitigates Demyelination and Neuroinflammation in a Cuprizone-Induced Model of Multiple Sclerosis Abstract Purpose This study focuses on the evaluation of the therapeutic potential of Tetrascorpin-1 (AaTs-1), a tetrapeptide isolated from Androctonus australis hector venom, proposed as a putative formyl peptide receptor 2 (FPR2) antagonist, in a cuprizone-induced murine model of Multiple sclerosis (MS), a chronic autoimmune and inflammatory disease of the central nervous system. Methods Acute demyelination was induced in mice by administering cuprizone (0.2% w/w in the diet) for six weeks. During the sixth week of cuprizone intake, demyelinated mice received intranasal administration of AaTs-1 at a dose of 50–100 µg/kg for five consecutive days, with 24-hour intervals between treatments. Results Behavioral assessments, immunological assays, and histological analyses revealed that AaTs-1 improved body weight, reduced behavioral impairments...

Theraphosid medicine: what to do when something is peculiar with the tarantula

Abstract

Background: With over 1060 species reported and a considerable number of these kept in captivity, theraphosid spiders, also known as tarantulas, have become a significant part of private and zoological collections, hence necessitating a greater demand for veterinary expertise.

Aim of the article: This comprehensive review addresses the unique challenges in tarantula care. It delves into the application of diagnostic tools like histology, radiography, haematology and microbiology in tarantulas, and discusses how to gather clinically relevant data for effective treatment planning of common conditions. It also outlines adaptations to cater treatments to tarantulas' unique anatomy, and offers guidance on drug selection and veterinary procedures, as well as covering humane euthanasia methods.
