DNA sequences encoding a porcine Galα(1,3) galactosyl transferase and clones containing such sequences are provided. The porcine Galα(1,3) galactosyl transferase produces the Galα(1,3) Gal epitope on the surfaces or porcine cells. This epitope is recognized by human anti-Galα(1,3) Gal antibodies which are responsible for hyperacute rejection of xenotransplanted pig cells, tissues and organs. Methods of reducing such hyperacute rejection are also provided.
本研究提供了编码猪Galα(1,3)半乳糖基转移酶的DNA序列和含有此类序列的克隆。猪 Galα(1,3)半乳糖基转移酶能在猪细胞表面产生 Galα(1,3) Gal 表位。人的抗 Galα(1,3)Gal 抗体可识别该表位,这种抗体是异种移植猪细胞、组织和器官产生超急性排斥反应的原因。还提供了减少这种超急性排斥反应的方法。
