Rapidly improving acute myocarditis after a scorpion sting

Türk Kardiyoloji Derneği Arşivi, 2013
Scorpion stings are usually benign, but especially cardiovascular death has been reported due to complications. Local reactions at the site of the sting as well as organ dysfunction may be due to the effects of a systemic toxin.

Characterization of a Novel BmαTX47 Toxin Modulating Sodium Channels: The Crucial Role of Expression Vectors in Toxin Pharmacological Activity

Toxins, 2014
Long-chain scorpion toxins with four disulfide bridges exhibit various pharmacological features towards the different voltage-gated sodium channel subtypes. However, the toxin production still remains a huge challenge.

The Scorpion Toxin Analogue BmKTX-D33H as a Potential Kv1.3 Channel-Selective Immunomodulator for Autoimmune Diseases

Toxins, 2016
The Kv1.3 channel-acting scorpion toxins usually adopt the conserved anti-parallel β-sheet domain as the binding interface, but it remains challenging to discover some highly selective Kv1.3 channel-acting toxins.

Scorpion toxins specific for Na⁺‐channels [PDF]

European Journal of Biochemistry, 1999
Na+‐channel specific scorpion toxins are peptides of 60–76 amino acid residues in length, tightly bound by four disulfide bridges. The complete amino acid sequence of 85 distinct peptides are presently known. For some toxins, the three‐dimensional structure has been solved by X‐ray diffraction and NMR spectroscopy.

Potassium Channels Blockers from the Venom of Androctonus mauretanicus mauretanicus

Journal of Toxicology, 2012
K+ channels selectively transport K+ ions across cell membranes and play a key role in regulating the physiology of excitable and nonexcitable cells. Their activation allows the cell to repolarize after action potential firing and reduces excitability ...
