Siglecs as Immune Cell Checkpoints in Disease - Annual Reviews

Siglecs are Type I transmembrane proteins where the NH3 -terminus is in the extracellular space and the COO -terminus is cytosolic. Each Siglec contains an N-terminal V-type immunoglobulin domain (Ig domain) which acts as the binding receptor for sialic acid. These lectins are placed into the group of … See more 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 … See more The first described candidate Siglec was Sialoadhesin (Siglec-1/CD169) a lectin-like adhesion protein on macrophages. Parallel studies by Ajit Varki and colleagues on the previously cloned CD22 (a B cell surface protein involved in adhesion and activation) showed direct … See more Many pathologies have been linked to the spontaneous interactions between sialic acid and the immunosuppressive sialic acid-binding immunoglobulin-like lectin (Siglec) receptors on immune cells such as cancer, HIV-1 and Group B Strep Infection. The See more The primary function of Siglecs is to bind glycans containing sialic acids. These receptor-glycan interactions can be used in cell adhesion, cell … See more This table briefly summarises the cellular distribution of each human/primate Siglec; the linkage specificity each has for sialic acid binding; the number of C2-Ig domains it contains; and … See more • Functional Glycomics Gateway, a collaboration between the Consortium for Functional Glycomics and Nature Publishing Group See more WebConversely, specific inhibition of MAG or sialyl-T MUC1 partially blocked adhesion. Immunohistochemical analysis of pancreatic perineural invasion showed the expression of both MUC1 and MAG. These results support the hypothesis that the adhesive interactions between MUC1 and MAG are of biological significance in pancreatic cancer perineural ... burning frankincense for protection
