Siglecs (Sialic acid-binding immunoglobulin-type lectins) are cell surface proteins that bind sialic acid. They are found primarily on the surface of immune cells and are a subset of the I-type lectins. There are 14 different mammalian Siglecs, providing an array of different functions based on cell surface receptor-ligand interactions. WebSiglecs are sialic-acid-binding immunoglobulin-like lectins that are mostly expressed by cells of the immune system. Siglecs can be divided into two subsets based on their sequence similarity and ...

WebSialic acids are typically found at the outermost ends of glycan chains, and have important function in many physiological and pathological processes, including pathogen binding and regulation of the immune response1. In human cells, the linkage position of a sialic acid to a glycan side chain can be α2,3 or α2,6 to a Webof laboratory and field isolates are also able to invade erythrocytes in a sialic acid-independent manner. The identity of the erythrocyte sialic acid-independent receptor has been a mystery for decades. We report here that the complement receptor 1 (CR1) is a sialic acid-independent receptor for the invasion of erythrocytes by P. falciparum.
