To investigate the role of enhanced antigen presentation in dendritic cell (DC)-based immunotherapy. Here, we describe the development of a cell-penetrating mucin 1 (MUC1) antigen and its immunotherapeutic potential against tumors. After animal groups received two immunizations of MUC1-MPA(11)P-pulsed DCs, we observed a marked tumor regression compared with the mice treated with DCs alone or DCs pulsed with MUC1 peptide. We confirmed the migration and homing of DCs in the popliteal lymph node using magnetic resonance imaging during the study. In summary, enhanced antigen uptake using an MPA(11)P delivery molecule improves cell therapy.
为了研究增强的抗原提呈在树突状细胞(DC)为基础的免疫疗法中的作用。在这里,我们描述了一种穿透细胞的粘蛋白 1(MUC1)抗原的开发及其针对肿瘤的免疫治疗潜力。在动物组接受两次 MUC1-MPA(11)P 脉冲 DC 免疫接种后,与单独用 DC 或用 MUC1 肽脉冲的 DC 治疗的小鼠相比,我们观察到肿瘤明显消退。在研究过程中,我们使用磁共振成像确认了 DC 在腘淋巴结中的迁移和归巢。总之,使用 MPA(11)P 递药分子增强抗原摄取可改善细胞治疗。
