    • The present invention describes a novel immunodeficient rodent model comprising an organ graft, such as a human skin graft, said graft containing microvessels lined by endothelial cells, human T lymphocytes and, optionally, at least one agent capable of substantially depleting the rodent's Natural Killer cells. The human T lymphocytes are engrafted and circulating in the animal's blood, enabling interaction with the endothelial cells which can be allogenic to the donor for the skin graft. The immunodeficient rodent used can be a SCID mouse. Preferably, the endothelial cells are provided by grafting said human skin with an intact dermal superficial vascular plexus. This immunodeficient rodent can be used as a model for studying inflammatory human immune responses of the engrafted T lymphocytes to foreign antigen as well as for studying human allograft rejection, e.g. human microvessel destruction and the T cell-endothelial cell in vivo interactions associated with a human allograft rejection.
    • 本发明描述了一种新型免疫缺陷型啮齿动物模型,其包括器官移植物,例如人皮肤移植物,所述移植物含有由内皮细胞排列的微血管,人T淋巴细胞和任选地至少一种能够消灭啮齿动物的天然杀伤细胞 。 人T淋巴细胞被植入并在动物的血液中循环,使得能够与内皮细胞相互作用,所述内皮细胞可以与皮肤移植物的供体同种异体。 使用的免疫缺陷型啮齿类动物可以是SCID小鼠。 优选地,通过用完整的真皮浅表血管丛移植所述人皮肤来提供内皮细胞。 该免疫缺陷型啮齿类动物可用作研究移植的T淋巴细胞对外源抗原的炎症性人免疫应答以及研究人类同种异体移植排斥反应的模型。 人类微血管破坏和与人类同种异体移植排斥相关的T细胞 - 内皮细胞体内相互作用。
