Despite the high therapeutic response achieved with B-cell maturation antigen (BCMA)-specific chimeric antigen receptor (CAR) T-cell therapy in relapsed and refractory multiple myeloma (R/R MM), primary resistance and relapse exist with single-target immunotherapy. Here, we design bispecific BC19 ...
但是,抗-cd20单克隆抗体(mab)有明显的局限性,包括原发性耐药(复发惰性患者中50%反应)、获得性耐药(再治疗时50%反应率)、罕有完全反应(复发群体中2%完全反应率)和连续的复发模式。最后,许多b细胞并不表达cd20,因此许多b-细胞障碍使用抗-cd20抗体疗法是不能治疗的。 除nhl以外,还有几种类型的由b细胞调节异常引起...
Approximately 60% of patients with large B cell lymphoma treated with chimeric antigen receptor (CAR) T cell therapies targeting CD19 experience disease progression, and neurotoxicity remains a challenge. Biomarkers associated with resistance and toxicity are limited. In this study, single-cell proteomic...
与初级人类b细胞结合.通过用percp-结合的抗人类cd20抗体、apc-标记的抗人 类cd3抗体和抗cd19双专一性抗体将人类pbmc共染色来测试人类b细胞的抗cd19 抗体结合。在用pbs缓冲液进行一轮短暂洗涤之后,向混合物中添加fitc-标记的抗 his标签抗体作为二级抗体以检测双专一性抗体。对于流式细胞测量术分析,通过阳性 cd20...
This is thought to result from the incomplete eradication of residual malignant B-lymphoid cells and/or their progenitors, and justifies the search for therapies that can eradicate these cells. The CD19, CD20 and CD22 antigens are expressed on a high percentage of malignant B-lymphoid cells in...
(A) Bone marrow aspirate from healthy donors were stained and analyzed by flow cytometry. The bottom right panel shows CD19 expression on CD138+CD38+ PCs (red) and CD20+CD19+ cells (blue); the green histogram represents CD138+CD38+ cells with fluorescence-minus-one (CD19) staining. Repre...
This is, for example, the case for CD19 and CD20 on B cells; dual-CD19/CD20 CAR-T cells are now under active investigation in B-cell leuke- mia and lymphoma [46–49]. Similarly, for MM, combi- natorial approaches with BCMA and other plasma cell surface antigens such as CD38 are...

Accordingly, we reasoned that broadening the spectrum of CD19CAR T-cells to include both CD20 and CD22 would enable them to target CD19(−) escape BL-ALL while preserving their upfront efficacy. We created a CD19/20/22-targeting CAR T-cell by coexpressing individual CAR molecules on a...
