Snaclecs (Snake C-Type Lectins) that Inhibit Platelet Receptors

Abstract

One of the major targets for snake venom proteins is haemostasis. This weakens the prey and helps with swallowing and digestion. The venom proteins act either on coagulation factors or on platelets. Snake venom proteins often adapt physiological mechanisms to inhibit or activate platelets. Inhibitory mechanisms are mainly directed against integrins, which is also true of many of the snaclecs described in this chapter. Their main physiological ligands are von Willebrand factor and collagen. GPIb is also a target of snaclecs described as inhibitory but that may be due to the methods of testing as such snaclecs induce thrombocytopenia when tested in vivo. In the case of those targeting integrins they may indeed be inhibitory but platelets may not be their primary target since α2β1 is also present on endothelial and smooth muscle cells and inhibitory molecules are anti-angiostatic.
