Siglecs are a family of sialic acid-binding immunoglobulin-like receptors that participate in the discrimination between self and non-self, and that regulate the function of cells in the innate and adaptive immune systems through the recognition of their glycan ligands.
Engagement of myelomonocytic siglecs by tumor-associated ligands modulates the innate immune response to cancer certain pathogenic bacteria are known to modulate the innate immune response by decorating themselves with sialic acids, which can engage the myelomonocytic lineage inhibitory receptor siglec-9, thereby evading immunosurveillance.
Siglecs are mostly inhibitory receptors similar to known immune checkpoints including pd-1 or ctla-4 that are successfully targeted with blocking antibodies for cancer immunotherapy. Here, we summarize the known changes of sialic acids in cancer and the role siglec receptors play in cancer immunity.
Siglecs have important roles in the regulation of activatory and inhibitory receptors on immune cells, which can influence host–pathogen interactions, inflammation, neurodegeneration, autoimmune.
Many siglecs are inhibitory receptors expressed on innate immune cells, they also have a role in maintaining b cell tolerance as well as modulating the activation of conventional and plasmocytic dendritic cells. Through these and other roles they contribute directly and indirectly to the regulation of t cell function.
Siglecs are proteins that bind to a sugar molecule, which is found attached to many other proteins, and are known to inhibit the immune response. However, it remained unclear how siglecs do this and if they can interact directly with toll-like receptors.
Many siglecs are inhibitory receptors expressed in innate immune cells that regulate inflammation mediated by damage-associated and pathogen-associated molecular patterns (damps and pamps). This family also includes molecules involved in adhesion and phagocytosis and receptors that can associate with the itam-containing dap12 adaptor.

Cancer cells also take advantage of the sialic acid-siglec interaction to induce immune tolerance.
Recent publications highlight the important roles siglecs play in tumor immunosurveillance making them attractive anti-cancer drug targets.
Siglecs are sialic acid-binding ig-like lectins expressed in a highly specific manner, and which are implicated in signaling and adhesive functions. The cd33-related siglecs represent a distinct subgroup that is undergoing rapid evolution within the innate immune system, with the potential to trigger apoptosis and provide inhibitory signals.

Sialic acid–binding immunoglobulin-type lectins (siglecs) are expressed on the majority of white blood cells of the immune system and play critical roles in immune cell signaling. Through recognition of sialic acid–containing glycans as ligands, they help the immune system distinguish between self and nonself.
Abstract sialic acid-binding immunoglobulin-like lectins (siglecs) are predominately expressed on immune cells. They are best known as regulators of cell signaling mediated by cytoplasmic tyrosine motifs and are increasingly recognized as receptors for pathogens that bear sialic acid-containing glycans. Most siglec proteins undergo endocytosis, an activity tied to their roles in cell signaling.

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.
