Platelets express a wide range of adhesion molecules such as integrins (including αIIbβ3/CD41, αVβ3, α2β1, α6β1 and so on), immunoglobulin superfamily proteins (PECAM-1), C-type lectin receptor family proteins (P-selectin, CLEC-2), leucine-rich glycoproteins (GPIb-IX-V), etc. These molecules are capable of bridging connections between platelets and vascular wall, tumor cells, and other platelets [9, 27, 45]. Here, ITGA2B is linked to neoplasm.
