Platelets are important in the formation of blood clots. For this reason, antiplatelet medications are commonly prescribed for people at risk of developing blood clots, or who have already developed one. Many of the medications that are currently on the market to treat blood clots come with a risk for excessive bleeding and reduced platelet numbers. Researchers have now discovered an effective antiplatelet protein in snake venom that is not associated excessive bleeding. Trowaglerix is a C-type lectin protein found in the venom of Wagler’s pit vipers (Tropidolaemus wagleri). Their promising results were recently published in Arteriosclerosis, Thrombosis, and Vascular Biology. The hope is to create safer antiplatelet medications.
