专利摘要:本发明公开了CD123靶向CAR‑NK细胞的制备及其应用,本发明设计并筛选获得了适用于CAR‑NK细胞制备的优选scFv分子,筛选可提升NK细胞扩增和活性的mIL‑15,通过高效转导体系和稳定冻存体系,可制备对AML以及其他CD123+肿瘤细胞具有显著杀伤活性的“现货型”CAR‑NK细胞,并在小鼠移植瘤模型中证实了抗肿瘤效应...
简单来说,在 CD123-NKCE或CD123-TCE存在条件下,将健康供体的PBMC培养20小时,并对IL-6、IL-1β、TNF-α和IFN-γ的分泌进行定量。即使在CD123-NKCE浓度高42倍的情况下,诱导释放的细胞因子水平也远低于CD123-TCE。于是作者继续在非人灵长类动物中进行药代动力学、药效学和毒理学研究,对雄性食蟹猴分别给予...
即使在CD123-NKCE浓度高42倍的情况下,诱导释放的细胞因子水平也远低于CD123-TCE。于是作者继续在非人灵长类动物中进行药代动力学、药效学和毒理学研究,对雄性食蟹猴分别给予高低剂量(3 mg kg−1和3 µg kg−1)...
4、存在一种靶蛋白cd19,其在白血病b细胞上强烈过表达,而健康非b细胞对该标志物呈阴性(ghorashian s,pule m,amrolia p.cd19 chimeric antigen receptor t celltherapy for haematological malignancies.br j haematol.2015;169:463–478)。因为cd19也在正常b细胞上表达,故在cd19-car-t输注后也消除了正常b谱系...

Alternative CD33/CD123 cotargeting strategies, aimed at better coverage without increasing on-target–off-leukemia toxicity, are being developed using technologies as diverse as CAR-T cells,51,59,60 single chain variable fragment NK-cell engager61 and targeted liposomes.62 These preclinical data are...
Chimeric antigen receptor (CAR) T cells targeting CD123, an acute myeloid leukemia (AML) antigen, hold the promise of improving outcomes for patients with refractory/recurrent disease. We generated five lentiviral vectors encoding CD20, which may serve as a target for CAR T cell depletion, and ...
