世界首例，中国团队将基因编辑猪肺成功移植人体

Core Insights - The research team from Guangzhou Medical University successfully transplanted a gene-edited pig lung into a human, marking a significant milestone in xenotransplantation [1][3][4] - The transplanted lung functioned for 9 days, demonstrating the potential of gene-edited organs to address the shortage of human organ donors [1][6][9] Group 1: Research Achievements - The pig lung was genetically modified using CRISPR technology to reduce immune rejection risks by silencing three genes and adding three human protein genes [9][11] - The patient, a 39-year-old brain-dead man, showed no immediate acute rejection of the pig lung, which is a common issue in organ transplants [4][11] - The study highlights the potential for gene-edited pig organs to be more compatible with human physiology, which could alleviate the organ donor shortage [3][6] Group 2: Clinical Observations - The transplanted lung maintained its function for 216 hours, with no signs of hyperacute rejection during the monitoring period [13][15] - Despite some immune response and organ damage observed, the lung was able to perform gas exchange effectively for the duration of the experiment [4][8][11] - The research team plans to optimize gene editing strategies and anti-rejection treatments to extend the survival and functionality of transplanted organs [8][15] Group 3: Future Directions - The study is seen as a step forward in the challenging field of xenotransplantation, with further research needed to address the challenges of organ rejection and infection [14][15] - Experts emphasize the importance of ethical considerations and safety protocols in conducting such high-risk research [15] - The research team aims to apply their findings to clinical settings, potentially transforming the landscape of organ transplantation [8][14]
