SIGLEC15

SIGLEC15,全稱為唾液酸結合免疫球蛋白樣凝集素15,別名包括CD33抗原樣3、SIGLEC-15、CD33L3、sialic acid-binding Ig-like lectin 15和Siglec15。在巨噬細胞上,SIGLEC15可以直接抑制T細胞活性,其作用機制與PD-1/PD-L1類似,能夠抑制T細胞活性,但不依賴PD-1/PD-L1途徑。此外,SIGLEC15表達與PD-L1的表達呈現互斥性,這預示著SIGLEC-15可能是一個補充治療靶點,為抗PD-1/PD-L1耐藥患者提供新的治療選擇。目前,SIGLEC-15在動物模型中顯示出較強的免疫抑制作用,但在人體內產生實際抗腫瘤作用尚不明確,相關研究也沒有突破性進展。NC318是目前唯一一款進入臨床試驗階段的SIGLEC-15單抗,但其在阻斷SIGLEC-15在人體內產生實際抗腫瘤作用上不明確,相關研究目前暫沒有突破性進展。
