研究概要

CD33 阴性细胞中存在融合基因,这些融合基因可能无法被 CD33 靶向治疗清除。这可能是复发的来源。

研究思路结论见上方概要

靶向治疗和免疫治疗是治疗白血病的新兴策略。CD33是细胞免疫治疗或抗体免疫治疗常见且重要的治疗靶点。靶向CD33的药物也在不断涌现。然而,急性髓系白血病(AML)在接受靶向CD33治疗后仍会复发,其机制尚不明确。

我们采用荧光原位杂交和实时聚合酶链反应检测AML患者不同细胞群体中融合基因的表达。

融合基因可在新诊断和复发AML患者的CD33阴性细胞比例中表达。

We used fluorescence in situ hybridization and real-time polymerase chain reaction to detect the expression of fusion genes in different populations of cells from AML patients. RESULT: Fusion gene can be express in CD33 negative cell proportions in newly diagnosed and relapsed AML patients.

There are fusion genes in CD33-negative cells that are might not be cleared by CD33 targeting therapy. And this might be the source of relapse.
