Immunogenicity of two representative American consensus scorpion neurotoxins from the genera Tityus and Centruroides. [PDF]

PLoS Neglected Tropical Diseases
Two consensus scorpion toxins derived from venoms of the genera Centruroides (NATx, North America), and Tityus (SATx, South America) were rationally designed and recombinantly expressed in Escherichia coli Origami. Both recombinant proteins were produced

Colombian Scorpion Centruroides margaritatus: Purification and Characterization of a Gamma Potassium Toxin with Full-Block Activity on the hERG1 Channel

Toxins, 2021
The Colombian scorpion Centruroides margaritatus produces a venom considered of low toxicity. Nevertheless, there are known cases of envenomation resulting in cardiovascular disorders, probably due to venom components that target ion channels. Among them,

Full Neutralization of Centruroides sculpturatus Scorpion Venom by Combining Two Human Antibody Fragments

Toxins, 2021
A fundamental issue of the characterization of single-chain variable fragments (scFvs), capable of neutralizing scorpion toxins, is their cross-neutralizing ability. This aspect is very important in Mexico because all scorpions dangerous to humans belong

Gene content evolution in the arthropods [PDF]

, 2020
Arthropods comprise the largest and most diverse phylum on Earth and play vital roles in nearly every ecosystem. Their diversity stems in part from variations on a conserved body plan, resulting from and recorded in adaptive changes in the genome ...
