| 1 | Serum anti‑blood type IgG/IgM binding and cytotoxicity to pig PBMC and RBC显示文摘Objective: TO investigate the killing differences of human blood group antibodies IgG and IgM on PBMC and RBC in peripheral blood of genetically modified pigs, and provide theoretical basis for the selection of pig blood group for clinical application of porcine xenotransplantation. Methods: Serum samples were collected from 20 healthy subjects, 20 patients with end‑stage renal disease and 20 brain dead organ donors, and divided into 4 groups on the basis of ABO blood group (A: n=20;B: n=17;AB: n=7;O: n=16). Flow cytometry was used to detect antibody binding or complement dependent cytotoxicity test (CDC) between human serum and O blood group Wild‑type (WT), α1, 3‑galactosyltransferase gene‑knockout(GTKO), cytidine monophosphate‑N‑acetylneuraminic acid hydroxylase gene‑knockout (GTKO/β4GalNT2KO), β‑1, 4N‑acetylgalactosaminyltransferase gene‑knockout(GTKO/CMAHKO) and mononuclear cells (PBMC) and red blood cells (RBC) of Triple knockout (TKO/hCD55) porcine peripheral blood, respectively. Results: There was no significant difference in binding and killing of human serum antibodies with blood group A, B, AB and O on PBMC of WT pigs, GTKO pigs, GTKO/β4GalNT2KO pigs, GTKO/CMAHKO pigs and TKO/hCD55 pigs, respectively. There was no significant difference in RBC binding with RBC of WT pig, GTKO pig, GTKO/β4GalNT2KO pig, GTKO/CMAHKO pig and TKO/hCD55 pig. Conclusion: The selection of recipients of pigs with type O blood group can be done without considering blood group. | CHEN Liang‑jie FENG Hao DU Jia‑xiang LI Tao XIA Qiang‑bing JIANG Hong‑tao PAN Deng‑ke CHEN Gang WANG Yi | 2023 | Journal of Hainan Medical University2023，29，2： | 0 |
