    • Transgenic non-human animals having genotypes comprising a first DNA sequence encoding an expression regulation sequence for a lymphoid gene operably linked to DNA encoding a lethal polypeptide. Also included are transgenic animals having genotypes comprising the substitution, deletion or insertion of one or more nucleotides in at least one endogenous allele of a CD3-type gene. The transgenic non-human animals have phenotypes characterized by immunodeficiency in at least one function of a lymphoid cell. Such phenotypes include depletion of one or more lymphoid cell types such as T-cells, NK cells, large granular lymphocytes, and/or B-cells. The invention also provides transgenic immunodeficient animals containing a xenograft characterized by a phenotype wherein the animal has an enhanced ability to maintain the xenograft as compared to the maintenance of the xenograft in the species from which the transgenic animal is derived.
    • 具有基因型的转基因非人动物包含编码与编码致死多肽的DNA可操作地连接的淋巴样基因的表达调控序列的第一DNA序列。 还包括具有基因型的转基因动物,其包含在CD3型基因的至少一个内源等位基因中取代,缺失或插入一个或多个核苷酸。 转基因非人动物具有以淋巴细胞的至少一种功能为特征的免疫缺陷表型。 这种表型包括一种或多种淋巴细胞类型的消耗,例如T细胞,NK细胞,大颗粒淋巴细胞和/或B细胞。 本发明还提供了转基因免疫缺陷动物,其含有特征在于表型的异种移植物,其中与在转基因动物得到的物种中的异种移植物的维持相比,该动物具有增强的维持异种移植物的能力。
