    • The present invention relates to apoptotic bodies derived from human tumor cells or cell lines recovered from patient's tumor biopsy and induced to apoptotis, said apoptotic bodies having the following characteristics: they maintain plasma membrane integrity, they are vesicles above about 0,1 &mgr;m, they contain intact mitochondria and cleaved nuclear DNA originating from the tumor cells, they present unmasked tumor antigens on their membranes, they present specific tumor and MHC antigens from the patient. The invention also provides new monocytes derived cells, which can be used as anti-tumor vaccines after integration of apoptotic bodies. Apoptotic bodies are phagocytosed and processed by monocyte derived antigen presenting cells and potentiate the effective tumor antigenic presentation to the immune system.
    • 本发明涉及源自人肿瘤细胞或从患者肿瘤活组织检查中诱导凋亡的细胞系的凋亡小体,所述凋亡小体具有以下特征:它们保持质膜完整性,它们是高于约0.1μm的囊泡,它们 含有源自肿瘤细胞的完整的线粒体和切割的核DNA,它们在其膜上存在未被掩蔽的肿瘤抗原,它们呈现来自患者的特异性肿瘤和MHC抗原。 本发明还提供新的单核细胞衍生细胞,其可以在凋亡小体整合后用作抗肿瘤疫苗。 细胞凋亡体被吞噬细胞并由单核细胞衍生的抗原呈递细胞处理,并增强免疫系统的有效肿瘤抗原呈递。
