In this review, we identify several snake venom toxins capable of affecting blood coagulation and the vascular system, as well as various toxins from other organisms, including leeches and ticks. The results showed that while no regression of atherosclerosis was observed, the lowering of serum cholesterol, prolonged blood clotting time and reduced fatty liver were significantly affected by the injection of one of the pooled protein fractions. High throughput screening and identification of coagulopathic snake venom proteins and peptides using nanofractionation and proteomics approaches. Epub 2019 May 30. XV. Although the molecular structures of most toxins are not unique to snake venom toxins, venom proteins often exhibit marked diversity in their biological effects, despite their structural similarities.

The venom of Agkistrodon halys was fractionated by DEAE-cellulose chromatography and the pooled protein fractions that resulted were injected intravenously into the quail with aortic atherosclerosis induced by dietary cholesterol. USA.gov. NLM USA.gov. The various components of snake venom toxins can be classified according to their mechanism of action, for example, serine proteases, metalloproteinases, Kunitz-type protease inhibitors, phospholipases A(2), (L)-amino acid oxidases, C-type lectin(-like) proteins, disintegrins, vascular endothelial growth factors, three-finger toxins, and cysteine-rich secretory proteins. eCollection 2019 Dec.
