Snake venoms, especially of Elapidae and Hydrophiidae, have been known for centuries to produce symptoms relevant to nervous systems in the envenomed subject. As described in detail in Chapter 24 and 25, the most characteristic symptom is the paralysis o
Despite the wide-array of snakes, venoms are mostly composed of four types of compounds: phospholipases, serine proteases, metalloproteases, and three-finger toxins, Barua said. Each type has unique physiological effects. For instance, three-finger toxins prevent nerve transmission, while phospholipa...
Protease is recognized as a common component in Hymenoptera venoms, which falls into the categories of metalloproteinase (MP) and serine protease (Table 3). Combined with Natterin-4, Phospholipase A2 (PLA2) and vascular endothelial growth factor toxin (VEGF-Tx), they were reported to induce ...
precipitation increases, and venomous pests start to breed. The custom of Dragon Boat Festival, which falls on the fifth day of the fifth lunar month, is to “repel the five venoms,” referring to the five types of venomous pests, which are generally considered...
Venoms, which have evolved numerous times in animals, are ideal models of convergent trait evolution. However, detailed genomic studies of toxin-encoding genes exist for only a few animal groups. The hyper-diverse hymenopteran insects are the most specio

It has been hypothesized that trophic innovations were the main drivers of rapid radiation of Neogastropoda in the late Cretaceous. We ...
Snakebite envenoming is a serious and neglected tropical disease that kills ~100,000 people annually. High-quality, genome-enabled comprehensive characterization of toxin genes will facilitate development of effective humanized recombinant antivenom.
