    • The invention is directed to an anergy-inducing cellular composition comprising: cells having antigenic determinants on the cell surface and an anergy-inducing compound [e.g., (−)-epigallocatechin-3-o-gallate (EGCG)] attached by its chemical affinity to the antigenic determinants. In one embodiment, the anergy-inducing compound blocks co-stimulatory molecules among the antigenic determinants of the cells, which upon encountering with T-cell renders the latter anergic, that is, unresponsive toward alloantigens. In another embodiment, EGCG is of high purity for its efficient attachment to the antigenic determinants. The anergy-inducing cellular composition is prepared by immersing the cells in a culture media solution (RPMI 1640) containing 50-500 ppm EGCG at low physiological temperatures for one to two hours to minimize the cells' mortality. A specific use of the resulting anergic cellular composition is suggested, which is the attenuation of two undesirable acute allogenic responses resulting from major histocompatibility disparity, namely, transplant rejection and GVHD.
    • 本发明涉及一种免疫诱导细胞组合物,其包含:在细胞表面具有抗原决定簇的细胞和通过其化学亲合力附着的无能力诱导化合物[例如( - ) - 表没食子儿茶素-3-邻氯乙酸酯(EGCG)] 对抗原决定簇。 在一个实施方案中,所述无反应诱导化合物阻断所述细胞的抗原决定簇之间的共刺激分子,其在与T细胞相遇时使得后者不敏感,即对同种异体抗原无反应。 在另一个实施方案中,EGCG与抗原决定簇的有效连接具有高纯度。 通过将细胞浸入含有50-500ppm EGCG的培养基溶液(RPMI 1640)中在低生理温度下浸泡1至2小时来制备无能诱导细胞组合物,以使细胞的死亡率最小化。 提出了所得到的无菌细胞组合物的具体用途,其是由主要组织相容性差异(即移植排斥和GVHD)引起的两种不希望的急性同种异体反应的减弱。
