The present study aims to develop chlorotoxin (CTX), from Giant Yellow Israeli scorpion venom, as a new BBB-shuttle. Minimised versions of CTX were prepared to reduce its complexity while enhancing its BBB-shuttle capacity and preserving its protease-resistance. MiniCTX3, a monocyclic lactam-bridge peptidomimetic, was capable of transporting nanoparticles across endothelial cell monolayers. Our results reveal animal venoms as an outstanding source of new families of BBB-shuttles.

The immune response is increasingly being linked to the pathogenic processes underlying neurological disorders including potassium channel malfunction. Few investigations, meanwhile, have shown how cyclooxygenase-2 (COX-2) is involved in the neuroimmunopathology linked to potassium channel failure. Thus, using an animal model of neuropathology caused by kaliotoxin, an exclusive blocker of voltage-gated potassium channels from the scorpion venom of Androctonus australis hector, we examined the immunomodulatory impact of celecoxib (selective inhibitor of COX-2).

Mosquitoes are responsible for the transmission of numerous pathogens, including Plasmodium parasites, arboviruses and filarial worms. They pose a significant risk to public health with over 200 million cases of malaria per annum and approximately 4 billion people at risk of arthropod-borne viruses (arboviruses). Mosquito populations are geographically expanding into temperate regions and their distribution is predicted to continue increasing.

Tityus serrulatus accident promote vast symptomatology related to toxins of the venom, which leads to a massive release of neurotransmitters, notably dopamine, affecting behavior and neurochemistry. The recommended treatment for envenomation is the antiscorpionic serum (SAEsc) administration. Related to this complexity of the Tityus serrulatus envenomation, this study aimed to assess organism responses to the venom, its impact on behavior, oxidative stress, neurochemistry, and genetic impacts, as well as the efficacy of SAEsc, especially concerning dopamine levels and genetic interactions.

Scorpion venom research aims to develop treatments for dangerous species and identify candidates for new drugs. The extraction of high-quality venom, which is essential, requires mastery of the extraction and maintenance of scorpions. It is in this perspective that we have undertaken this present work which aims to contribute to scientifically mastering venom yields and the factors that influence them in scorpions.
