背靠背三篇Science论文:David Baker团队中国博后利用AI从头设计TCR,加速癌症免疫治疗
生物世界· 2025-07-25 04:05
Core Viewpoint - The article discusses the advancements in cancer immunotherapy through the use of generative AI to design artificial T-cell receptors (TCRs) that can specifically bind to pMHC complexes, overcoming the limitations of natural TCRs and enabling more precise targeting of tumor antigens [4][21][23]. Group 1: Traditional TCR Methods - Traditional methods for utilizing TCR in cancer immunotherapy involve isolating T cells from patients, either through tumor-infiltrating lymphocytes (TILs) or expanding T cells from an initial T cell library, which is technically challenging and labor-intensive [3]. - Natural TCRs often have poor affinity for tumor antigens, making it difficult to achieve effective immunotherapy [3]. Group 2: Generative AI Research - On July 24, 2025, three research papers published in the journal Science demonstrated the use of generative AI to design artificial TCRs that can bind with high specificity to pMHC complexes, thus enhancing the precision of tumor antigen targeting [4][5][21]. - The research teams involved include those from the University of Washington, Technical University of Denmark, and Stanford University [5]. Group 3: Protein Design and Functionality - The David Baker/Liu Bingxu team developed a computational method to enhance the immune system's ability to recognize and destroy cells carrying less detectable disease markers by designing proteins that specifically recognize target pMHC complexes [10]. - The designed proteins were tested against 11 different pMHC targets, including fragments from HIV and cancer-related mutations, with 8 of them successfully activating immune cells [13]. - The study confirmed that the designed proteins only bind to their specific targets, achieving atomic-level precision in construction [14]. Group 4: Rapid and Scalable Design Process - The design process demonstrated high adaptability, allowing the creation of new versions of binding proteins for different tumor and viral peptide targets in less than a week [16]. - This digital approach contrasts with traditional drug development methods, significantly shortening the drug development cycle and reducing complexity, while paving the way for more personalized therapies [16]. Group 5: Future Directions and Company Formation - The lead author, Dr. Liu Bingxu, indicated plans to establish a company to translate these research findings into therapies that can benefit patients [18]. - The research highlights the potential for artificial TCRs to revolutionize diagnostic tools and immunotherapies, particularly for diseases that currently lack effective treatments [22][23].
