The venom of a single spider can contain up to 3000 components. These components, mostly peptides, can be used to develop promising drug leads for the treatment of diseases. Spider venom can also be used as a biological pesticide. A team of scientists from the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Justus Liebig University in Giessen is primarily researching the venoms of spiders native to Germany, which have mostly been neglected until now. Their results regarding the biology of the toxins, in particular from the venom of the wasp spider, have been published in the journals “Biomolecules” and “Biological Reviews”.
