Immune system hyperactivation are involved with clinical severity and pathological alterations during scorpion envenomation. In a murine model, mice inoculated with a lethal dose of Tityus serrulatus scorpion venom presented mitochondrial swelling in cardiomyocytes, with other structures such as sarcomeres and intercalated disks preserved. Treatment with dexamethasone or knockout animals to the interleukin-1β receptor do not undergo mitochondrial changes in cardiomyocytes during envenomation.
