Backbround: Many tumors express tumor-associated antigens (TAA). Antigen presenting cells (APC), such as dendritic cells (DC) process and present TAAs to T cells, thereby eliciting a tumor-specific immune response.

• 研究背景和目的:许多肿瘤都能表达肿瘤相关抗原(TAA),包括肝癌和结直肠癌,这些抗原被抗原递呈细胞(APC)摄取、加工处理后可传递给T淋巴细胞,进而诱导出特异性的抗肿瘤免疫反应。
