Siglec-15 Promotes the Proliferation and Migration of Colorectal Cancer Cells and Inhibits the Infiltration of CD4 / 中国生物化学与分子生物学报

Sialic acid binding immunoglobulin type lectin-15 (Siglec-15), one of the Siglec gene family members, is a new immunosuppressive molecule. Siglec-15 is highly expressed in a variety of human tumor cells and tumor-associated macrophages, but the biological function of Siglec-15 in colorectal cancer (CRC) and its effect on the tumor immune microenvironment remains poorly understood. This study aimed to investigate the effects of aberrant expression of Siglec-15 on the biological behaviors of CRC cells and the infiltration of CD4
