Scorpionism is a serious public health problem in various regions of the world. In Brazil, a high number of accidents by scorpions have been reported. From 2014 to 2018, about 547,000 cases were recorded, resulting in 466 deaths. The scorpion Tityus stigmurus is the predominant species in the northeast of Brazil, being responsible for most scorpionism cases in this region. With the aid of the transcriptomic approach of the venom gland of this species, components as neurotoxins, antimicrobials, metal chelating peptides and hypotensins, have been identified and characterized in silico, showing different biologic activity in vitro. In addition, the neuronal, pancreatic, renal, and enzymatic effects have been demonstrated for the crude T. stigmurus venom. Therefore, the T. stigmurus scorpion venom constitutes a rich arsenal of bioactive molecules with high potential for therapeutic and biotechnological application.
蝎蜇伤在世界各地区都是一个严重的公共卫生问题。在巴西,已报告大量蝎子蜇伤事故。2014年至2018年期间,记录了约54.7万例病例,导致466人死亡。巴西游走蛛是巴西东北部的主要蝎子种类,该地区大多数蝎蜇伤病例都由其导致。借助对该物种毒腺的转录组学方法,已在计算机上鉴定并表征了神经毒素、抗菌剂、金属螯合肽和降血压素等成分,它们在体外显示出不同的生物活性。此外,还证实了巴西游走蛛粗毒对神经元、胰腺、肾脏和酶的作用。因此,巴西游走蛛的蝎毒构成了一个丰富的生物活性分子库,具有很高的治疗和生物技术应用潜力。
