摘 要
肿瘤免疫治疗作为近年来生物医学领域的研究热点，为多种恶性肿瘤的治疗提供了新的思路。抗体工程作为一种关键技术，在提高抗肿瘤免疫反应和靶向治疗效果方面展现出巨大潜力。本研究旨在探讨抗体工程在肿瘤免疫治疗中的创新应用及其临床转化价值。通过结合基因工程技术、蛋白质工程优化以及计算辅助设计等方法，本研究开发了多种新型抗体结构，包括双特异性抗体、抗体药物偶联物（ADC）和嵌合抗原受体T细胞（CAR-T）相关抗体。实验结果表明，这些新型抗体能够显著增强对肿瘤细胞的特异性识别能力，并有效激活宿主免疫系统以清除肿瘤细胞。特别是在双特异性抗体的设计中，通过引入特定的分子桥接机制，实现了同时靶向肿瘤抗原和免疫检查点的功能，从而克服了传统单克隆抗体的局限性。此外，本研究还验证了抗体药物偶联物在降低毒副作用的同时提升治疗效果的可行性。最终结论显示，抗体工程不仅能够显著改善现有肿瘤免疫疗法的效果，还为个性化医疗提供了重要的技术支撑。本研究的创新点在于首次提出并验证了多靶点协同作用的抗体设计策略，为未来肿瘤免疫治疗的精准化和高效化奠定了理论和技术基础。

Abstract
Tumor immunotherapy, as a research hotspot in the field of biomedicine in recent years, has provided new insights into the treatment of various malignant tumors. Antibody engineering, as a key technology, has demonstrated great potential in enhancing anti-tumor immune responses and improving the efficacy of targeted therapies. This study aims to explore the innovative applications of antibody engineering in tumor immunotherapy and its clinical translation value. By integrating gene engineering techniques, protein engineering optimization, and computationally assisted design, this study developed several novel antibody structures, including bispecific antibodies, antibody-drug conjugates (ADCs), and chimeric antigen receptor T-cell (CAR-T) related antibodies. The experimental results indicate that these novel antibodies significantly enhance the specific recognition of tumor cells and effectively activate the host immune system to eliminate tumor cells. Particularly in the design of bispecific antibodies, the introduction of a specific molecular bridging mechanism enabled simultaneous targeting of tumor antigens and immune checkpoints, thereby overcoming the limitations of traditional monoclonal antibodies. Additionally, this study validated the feasibility of ADCs in reducing toxic side effects while enhancing therapeutic efficacy. The final conclusion shows that antibody engineering not only markedly improves the effectiveness of existing tumor immunotherapies but also provides crucial technical support for personalized medicine. The innovation of this study lies in the first proposal and validation of a multi-target synergistic antibody design strategy, laying a theoretical and technical foundation for the precision and efficiency of future tumor immunotherapy.
