Electrophysiological Characterization of the Antarease Metalloprotease from Tityus serrulatus Venom
Scorpions are among the oldest venomous living organisms and the family Buthidae is the largest and most medically relevant one. Scorpion venoms include many toxic peptides, but recently, a metalloprotease from Tityus serrulatus called antarease was reported to be capable of cleaving VAMP2, a protein involved in the neuroparalytic syndromes of tetanus and botulism. We have produced antarease an...
متن کاملToxicity of crude and detoxified Tityus serrulatus venom in anti-venom-producing sheep
Specific anti-venom used to treat scorpion envenomation is usually obtained from horses after hyperimmunization with crude scorpion venom. However, immunized animals often become ill because of the toxic effects of the immunogens used. This study was conducted to evaluate the toxic and immunogenic activities of crude and detoxified Tityus serrulatus (Ts) venom in sheep during the production of ...
متن کاملMolecular, Immunological, and Biological Characterization of Tityus serrulatus Venom Hyaluronidase: New Insights into Its Role in Envenomation
BACKGROUND Scorpionism is a public health problem in Brazil, and Tityus serrulatus (Ts) is primarily responsible for severe accidents. The main toxic components of Ts venom are low-molecular-weight neurotoxins; however, the venom also contains poorly characterized high-molecular-weight enzymes. Hyaluronidase is one such enzyme that has been poorly characterized. METHODS AND PRINCIPAL FINDINGS...
متن کاملThe dynamics of cytokine d nitric oxide secretion in mice injected with Tityus serrulatus scorpion venom.
AIMS The effects of Tityus serrulatus venom (TSV) were analysed with respect to the susceptibility of four isogenic mouse, the symptoms following injection of venom and the inflammatory mediators in an experimental model of severe envenomation induced in mice. METHODS The susceptibility was analysed by lethal dose (LD50) determination, including the symptoms observed during envenomating and g...
متن کاملProteomic endorsed transcriptomic profiles of venom glands from Tityus obscurus and T. serrulatus scorpions
BACKGROUND Except for the northern region, where the Amazonian black scorpion, T. obscurus, represents the predominant and most medically relevant scorpion species, Tityus serrulatus, the Brazilian yellow scorpion, is widely distributed throughout Brazil, causing most envenoming and fatalities due to scorpion sting. In order to evaluate and compare the diversity of venom components of Tityus ob...
