This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. A variety of diseases can be cured by bone marrow or blood transplantation, but this procedure is frequently complicated by a harmful immune reaction of donor cells against the recipient. Previous studies have shown that an agonistic CD28-specific antibody that binds to donor cells can prevent this immune reaction in mice. We have made a similar antibody that binds to human donor cells, but we do not know whether this antibody could prevent the immune reaction after bone marrow or blood transplantation. This antibody also binds to non-human primate donor cells but not against dog or mouse donor cells. The FDA will not allow testing of the antibody in humans, unless prior testing has been done in nonhuman primates to show that the antibody is safe and effective. The pilot study proposed in this application is intended to provide initial information that could be used to assess the merits of further studies with the use of this antibody as a way of preventing immune reactions after bone marrow or blood transplantation. The results of this project showed that the CD28 antibody did not prevent the harmful immune reaction of donor cells against the recipient. The project has been closed.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目及 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 多种疾病可以通过骨髓或血液移植来治愈，但该过程常常因供体细胞对受体的有害免疫反应而变得复杂。先前的研究表明，与供体细胞结合的激动性 CD28 特异性抗体可以阻止小鼠的这种免疫反应。我们已经制作了一种类似的抗体，可以与人类供体细胞结合，但我们不知道这种抗体是否可以阻止骨髓或血液移植后的免疫反应。该抗体还与非人灵长类供体细胞结合，但不与狗或小鼠供体细胞结合。 FDA 不允许在人体中测试该抗体，除非事先在非人类灵长类动物中进行过测试以表明该抗体是安全有效的。本申请中提出的初步研究旨在提供初步信息，可用于评估使用该抗体作为预防骨髓或血液移植后免疫反应的方法的进一步研究的优点。 该项目的结果表明，CD28抗体并不能阻止供体细胞针对受体的有害免疫反应。该项目已关闭。
