CD123-targeted therapy in acute myeloid leukemia - PubMed
Monoclonal antibodies targeting AML-specific surface markers have emerged as promising candidates to improve outcomes. CD123, interleukin-3 receptor alpha chain [IL-3 Rα], is highly expressed in AML, particularly within the AML stem cell compartment.
三个强劲靶点直击AML— CD33,CD123,CLEC12A - 知乎
近年来,研究人员发现,以CD33、CD123及CLEC12A为靶点的免疫靶向疗法来治疗AML效果显著(图1),本文将围绕这三个靶点的分子特征、药物开发进展等方面做简单分享。 图1. 靶向CD33CLL1CD123治疗AML的药物开发策略. CD33是Siglecs家族的67 kDa 糖基化跨膜蛋白(图2),它通过交联或与配体结合后被激活,介导细胞内的抑制性信号,还具有调节细胞内钙动员、细胞粘附、白血病细胞凋亡、骨髓细胞成熟和细胞因子产生等作用。 研究显示,CD33在90% …
Nat Med:骨髓支持细胞因子使得AML患者对靶向CD123的CAR-T …
在一项新的研究中,来自宾夕法尼亚大学的研究人员探究了源自患者的抗CD123 CAR-T细胞在治疗复发或难治性急性髓性白血病(AML)成人患者中的应用。 相关研究结果于2024年9月27日在线发表在 Nature Medicine 期刊上,论文标题为 “Cytokine-mediated CAR T therapy resistance in AML”。 虽然大多数参与者都成功接受了CAR-T细胞治疗,但是研究结果突显了细胞因子释放综合征(CRS)带来的巨大挑战和相对较低的临床反应率。 这表明,将CAR T细胞疗法与细胞因 …
Targeting CD123 in acute myeloid leukemia using a T …
2016年1月7日 · In this study we demonstrate that the CD3×CD123 DART binds to both human CD3 and CD123 to mediate target-effector cell association, T-cell activation, proliferation, and receptor diversification. The CD3×CD123 DART also induces a dose-dependent killing of AML cell lines and primary AML blasts in vitro and in vivo.
CD123 as a Biomarker in Hematolymphoid Malignancies: …
In AML, the levels of CD123, GM-CSF, interleukin-2 receptor alpha chain (IL-2Rα; CD25), common gamma-chain cytokine (γc), c-kit, and granulocyte colony-stimulating factor receptor (G-CSFR) were widely expressed with a range of more than 10,000 sites/cell, and their expression patterns correlated with morphologic subtypes [36,37].
Cytokine Release Syndrome Results in Reduced AML Killing By …
2023年11月2日 · Specifically, co-incubation of CART-123 cells and cytokine-exposed primary AML blasts leads to increased populations of PD-1+/CD39+/CTLA4+/LAG3+ CAR T cells, consistent with an exhaustion phenotype. Finally, we found that anti-apoptotic effects of cytokines can be prevented, and CART-123 killing of AML can be restored, via ruxolitinib blockade ...
靶向CD123嵌合抗原受体T细胞治疗急性髓系白血病最新进展
CD123是急性髓系白血病(acute myeloid leukemia,AML)相关抗原,高表达于白血病干细胞,低或不表达于正常造血干祖细胞,是AML的潜在治疗靶点。 本文就目前靶向CD123的细胞免疫治疗技术治疗急性髓细胞白血病的最新进展做一综述。
Targeting CD123 in AML - ScienceDirect
2020年9月1日 · In AML, CD123 is expressed on both the bulk blasts and is particularly enriched in the so-called leukemia stem cells (LSCs) or leukemia-initiating cells (LICs) measured in experimental assays and by immunophenotype.
CD123在急性髓系白血病患者骨髓异常细胞群中的表达及预后价值
cd123在aml白血病细胞及lsc中均表达较高,提示cd123是aml的一个潜在免疫治疗靶点,最近,部分靶向cd123的抗体药物正在进行或已经完成Ⅰ期临床试验 – ,而靶向cd123的细胞免疫治疗也已取得显著进展。
CD123靶向抑制剂治疗急性髓细胞白血病的研究新进展 - 国际输血 …
CD123,即白细胞介素-3受体 (interleukin-3 receptor,IL-3R)α,是AML相关抗原及白血病干细胞 (leukemia stem cell,LSC)的特异性标志物之一,其在LSC及大部分白血病细胞表面高表达,而在正常的原始造血细胞和红系祖细胞中低表达或者不表达 [7]。 CD123对白血病的发生、发展,以及维持白血病细胞的一系列生物学功能均有重要影响,并且与AML患者预后不良及疾病复发密切相关 [8, 9]。 近年,CD123已成为AML治疗的重要靶点之一,各种类型的CD123靶向抑制剂正在研发 …
