Hintergrund: Siglec proteins (sialic acid binding Ig-like lectins) are type I membrane proteins with an extracellular region which contains a sialic acid binding V-set Ig-like domain at the N-terminus, followed by varying numbers of C2-set Ig domains. In the cytosolic domain, most siglecs contain a combination of tyrosine motifs that include immunoreceptor tyrosine-based inhibitory motifs (ITIMs) along with ITIM-like, Grb2-binding, and Fyn kinase sites. Siglecs are widely expressed on hematopoietic cells, often in a cell type specific manner. Their ligands, sialic acids, are negatively charged monosaccharides found on cell surface glycoproteins and glycolipids. Studies suggest that Siglecs may participate in cell-to-cell interactions or can act as receptors during the entry of viral or bacterial pathogens. In addition, the presence of ITIMs indicate that these molecules play a role in the suppression of immunoreceptor signaling. Siglecs can be classified into two subgroups with Siglec 1, 2, and 4 as one group and a Siglec 3/CD33-related subgroup (Siglec 3 and Siglec 5 - 14) as the second. Siglec 5, a human CD33-related Siglec, selectively regulates early recruitment of neutrophils in the lung during lipopolysaccharide-induced acute lung inflammation.
