               [摘   要] 唾液酸结合免疫球蛋白样凝集素(sialic acid⁃binding immunoglobulin⁃like lectin,Siglec)家族是一类广泛表达于免疫
                细胞表面的免疫调节受体,其异常表达与肿瘤免疫逃逸、机体炎症反应及自身免疫性疾病的发生密切相关。目前,Siglec受体
                作为肿瘤及炎性疾病的潜在分子靶点受到广泛关注。在诊断领域,基于Siglec受体开发的放射性分子探针已在正电子发射型
                计算机断层扫描(positron emission computed tomography,PET)和单光子发射型计算机断层扫描(single⁃photon emission computed
                tomography,SPECT)等分子影像技术中得到发展与应用。在治疗领域,Siglec靶向的α核素( Ac、 At)和β核素( Lu)标记探针
                                                                                         211
                                                                                                     177

                通过靶向放疗可实现对病灶的精准杀伤,特别是在血液肿瘤的治疗中显示出优势。文章评述了近年来靶向Siglec家族的放射
                性核素诊疗探针的相关研究进展,对探针的性能及其临床应用价值进行了分析,以期为Siglec靶向分子探针的研发及临床应
                用提供参考。

               [Abstract] The sialic acid ⁃ binding immunoglobulin ⁃ like lectin(Siglec)family comprises a group of immunoregulatory receptors
                broadly expressed on the surface of immune cells. Its aberrant expression is closely linked to tumor immune evasion,systemic
                inflammatory responses,and the pathogenesis of autoimmune diseases. Currently,Siglec receptors have received extensive attention as
                potential molecular targets for tumors and inflammatory disorders. In the field of diagnosis,radiopharmaceutical molecular probes
                based on Siglec receptors have been developed and applied in molecular imaging such as positron emission computed tomography
               (PET)and single ⁃ photon emission computed tomography(SPECT). In the field of therapy,Siglec ⁃ targeted probes labeled with α
                nuclides(such as  225 Ac and  211 At)and β nuclides(such as  177 Lu)enable precise ablation of the focal lesion through targeted radiotherapy,
                showing advantages particularly in the treatment of hematological malignancies. This article summarizes recent research progress in
                Siglec⁃targeted radiopharmaceuticals,and analyzes their performance and clinical application value,aiming to provide insights for the
                development and clinical application of novel Siglec⁃targeted molecular probes.
