Abstract:

Siglecs are cell surface transmenbrane receptor and are expressed on the immune cells, which regulated the immune balance in inflammation diseases. Sepsis is organ dysfunction induced by infection, the pathogenesis of sepsis contains the immune disorder, inflammatory reaction and coagulation dysregulation. In this article, we reviewed the role of Siglecs in the pathogenesis of sepsis was reviewed. Siglec-1, Siglec-5 and Siglec-14 play bidirectional role by regulating the inflammation and immunity. Siglec-2 modulates the immune balance in inflammation through regulating B cell and T cell response. Siglec-9 modulates macrophagepolarization and restrain the function of neutrophils during infection through the endocytosis of toll-like receptor 4 (TLR4). Siglec-10 inhibits the danger-associated molecular pattern (DAMP) and helps T cells initiate antigen-antibody responses, and reduces the number of B cells, thus reducing inflammation. Modulation of Siglecs function in different stages of sepsis have potential therapeutic significance in the treatment of sepsis.

Key words: Siglecs, Infection, Sepsis, Inflammation
