决定异体 CAR T 细胞排斥与扩增的细胞和分子机制
Cellular and molecular mechanisms determining allogeneic CAR T cell rejection and expansion.
我们评估了11例接受单一批次cemacabtagene ansegedleucel(cema-cel)治疗的大B细胞淋巴瘤患者,cemacabtagene ansegedleucel是一种异体抗CD19 CAR T产品。
英文原题:Seeing Is Believing: IEC-HS after CAR T Cells.

免疫效应细胞相关噬血细胞性淋巴组织细胞增生症样综合征(IEC-HS)是接受嵌合抗原受体(CAR)T 细胞患者中出现的并发症,与 CD19 相比,在 CD22 或 BCMA 靶向构建体患者中更为常见。
免疫效应细胞相关噬血细胞性淋巴组织细胞增多症样综合征(IEC-HS)是嵌合抗原受体(CAR)T细胞治疗的一种并发症;与靶向CD19的构建体相比,接受靶向CD22或BCMA构建体治疗的患者中更常见。IEC-HS与CAR-T细胞扩增增加及独特的细胞因子谱相关,其中IFNγ、IL-10和IL-1受体拮抗剂(IL-1RA)三种细胞因子的组合与IEC-HS严重程度相关性最强,可能有助于指导预先干预。相关研究见Srinagesh等人发表的文章,第225页。
Immune effector cell-associated hemophagocytic lymphohistiocytosis-like syndrome (IEC-HS) is a complication seen in patients receiving chimeric antigen receptor (CAR) T cells, more frequently in those with CD22- or BCMA-targeted constructs compared with CD19. While associated with higher CAR T-cell expansion and a unique cytokine profile, the constellation of three cytokines (IFN , IL10, and IL1RA) correlated most strongly with IEC-HS severity and may help guide preemptive interventions.
