    • Porcine striatal cells and methods for using the cells to treat neurological deficits due to neurodegeneration are described. The porcine striatal cells can be modified to be suitable for transplantation into a xenogeneic subject, such as a human. For example, the porcine striatal cells can be modified such that an antigen (e.g., an MHC class I antigen) on the cell surface which is capable of stimulating an immune response against the cell in a xenogeneic subject is altered (e.g., by contact with an anti-MHC class I antibody, or a fragment or derivative thereof) to inhibit rejection of the cell when introduced into the subject. In one embodiment, the porcine striatal cells are obtained from a pig which is essentially free from organisms or substances which are capable of transmitting infection or disease to the recipient subject. The porcine striatal cells of the present invention can be used to treat neurological deficits due to neurodegeneration in the brain of a xenogeneic subject (e.g., a human with epilepsy, head trauma, stroke, amyotrophic lateral sclerosis, Parkinson's disease, Alzheimer's disease, or Huntington's disease) by introducing the cells into the brain of the subject.
    • 描述了猪纹状体细胞和使用细胞治疗由于神经变性引起的神经缺陷的方法。 猪纹状体细胞可以被修饰为适合于移植到异种受试者(例如人)中。 例如,可以修饰猪纹状体细胞,使得在异种受试者中能够刺激针对细胞的免疫应答的细胞表面上的抗原(例如MHC I类抗原)被改变(例如,通过与 抗MHC I类抗体或其片段或衍生物),以抑制当引入受试者时细胞的排斥反应。 在一个实施方案中,猪纹状体细胞从基本上不含能够将感染或疾病传播给接受者的生物或物质的猪获得。 本发明的猪纹状体细胞可用于治疗异种受试者的脑部神经变性(例如,患有癫痫,头部创伤,中风,肌萎缩性侧索硬化,帕金森病,阿尔茨海默病或亨廷顿病 疾病)通过将细胞引入受试者的脑中。
