Bee and scorpion venom to make drugs

Extensive article published in Sunday’s issue of ARA on the research line developed by Meritxell Teixidó in Ernest Giralt’s lab to extract natural poison from bees, scorpions and spiders, which provides peptides able to cross the blood-brain barrier. Many drugs cannot enter the brain because of this barrier, which serves to protect this organ against infections. Several projects at IRB Barcelona seek to find and modify natural peptide venoms that have the capacity to cross this barrier without damaging it, in order to use them as drug transporters into the brain.
