Functions and therapeutic targets of Siglec-mediated infections, inflammations and cancers

Siglecs, sialic acid (SA)-binding immunoglobulin (Ig)-like lectins, belong to a family of Ig-like lectins. All Siglecs have at least two domains including an extracellular domain with variable (V) and constant (C)-set immunoglobulin (Ig) regions, and a transmembrane domain. Some of the Siglecs (Sigl...

description Siglecs, sialic acid (SA)-binding immunoglobulin (Ig)-like lectins, belong to a family of Ig-like lectins. All Siglecs have at least two domains including an extracellular domain with variable (V) and constant (C)-set immunoglobulin (Ig) regions, and a transmembrane domain. Some of the Siglecs (Siglec-2–12, −17, -E, -F and -G) with three domains including immunoreceptor tyrosine-based inhibitory motif associated with Src homology 2 (SH2) tyrosine phosphatases (SHP1/2) usually deliver an inhibitory signal. Certain Siglecs (Siglec-14, -15, −16 and -H) containing no intracellular domain carry certain basic amino acid in transmembrane domain coupled with immunoreceptor tyrosine-based activating motif for cell activation. The number of Siglec-encoding genes has been correlated to lifespan of mammals, indicating its evolutional advantage on acquisition of Siglecs in humans. Certain polymorphisms of Siglecs have been associated with premature delivery, infection, schizophrenia, allergy, dementia or chronic obstructive pulmonary disease. Siglecs mainly expressing on leukocytes could interact with cis- or trans-SA ligands for cell–cell and host–organism interactions on infections, inflammations and cancers. Amplifying or eliminating the SA-Siglec interactions is a promising strategy to treat cancers, infections and inflammations, based on SA modifications in different linkages or nanoparticle decoration, and on the antibodies in conjugation of chimeric receptor design or toxins.
