Abstract
Sialic acid-binding Ig-like lectins (SIGLECS) are major members of the immune receptor superfamily, express in various immune cells, and are able to recognize specific sialic acids. Studies have found that they inhibit the anti-tumor activity mediated by myeloid cells, natural killer cells, and T cells. SIGLEC15 is a member of the SIGLEC family of glycine recognition proteins and is mainly expressed in a subset of myeloid cells. It is known that SIGLEC15 is involved in osteoclast differentiation and is considered as a potential therapeutic target for osteoporosis. In this review, we have concluded that SIGLEC15 has an unexpected role in immunomodulation and cancer microenvironment, thereby expanding the potential pathophysiological role of SIGLEC15, to provide a theoretical basis for the diagnosis and treatment of diseases.
Key words:
