Cell-Based Adhesion Assays for Isolation of Snake Venom's Integrin Antagonists

Methods Mol Biol. 2020:2068:205-223. doi: 10.1007/978-1-4939-9845-6_11.

Abstract

Snake venoms could lead to the development of new drugs to treat a range of life-threatening conditions like cardiovascular diseases. Most snake venoms contain a large variety of lethal toxins as well as anti-adhesive proteins such as disintegrins, which have evolved from the harmless compounds ADAMs (proteins with a disintegrin and a metalloprotease domain) and C-type lectin proteins which disturb connective tissue and cell-matrix interaction. These anti-adhesive proteins target and block integrin receptors and disrupt normal biological processes in snakes' prey such as connective tissue physiology and blood clotting. This chapter provides the experimental details of a practical, cell-based adhesion protocol to help identify and isolate disintegrins and C-type lectin proteins from snake venoms, important tools in integrin research and lead compounds for drug discovery.

Keywords: Adhesion; C-type lection protein; Disintegrin; Integrin; Method; Snake venom; Toxin.
