Inhibition of Tityus serrulatus venom hyaluronidase affects venom biodistribution [PDF]
PLoS Neglected Tropical Diseases, 2019 BackgroundThe hyaluronidase enzyme is generally known as a spreading factor in animal venoms. Although its activity has been demonstrated in several organisms, a deeper knowledge about hyaluronidase and the venom spreading process from the bite/sting ...

The nociceptive response induced by different classes of Tityus serrulatus neurotoxins: The important role of Ts5 in venom-induced nociception [PDF]
PLoS Neglected Tropical Diseases, 2023 Scorpion sting envenomations (SSE) are feared by the intense pain that they produce in victims. Pain from SSE is triggered mainly by the presence of neurotoxins in the scorpion venom that modulates voltage-gated ion channels.
