中文摘要

CAR-T 细胞在人体内活化时的能量代谢仍未得到研究。作为糖酵解活性的替代指标,我们考察了CAR-T 输注后数周内外周血(PB)乳酸的动态变化。17例复发/难治性非霍奇金淋巴瘤患者接受含CD28共刺激结构域的抗CD19 CAR-T 治疗后,PB乳酸水平升高。乳酸水平升高与CAR-T 细胞持续时间更长及CD8+/CD4+比值更高相关。外周血乳酸动态变化可能反映免疫细胞活化,并可用于床旁监测。

Energy metabolism of chimeric antigen receptor-T cells (CAR-T) activation in humans remains unexplored. As a glycolytic activity surrogate, we investigated the dynamics of peripheral blood (PB) lactate in the first weeks post-CAR-T infusion.

In 17 patients treated with CD28 harbording anti-CD19 CAR-T for relapsed/refractory non-Hodgkin lymphomas, PB lactate levels increased following CAR-T infusion. Elevated lactate levels correlated with longer CAR-T persistence and higher CD8+/CD4+ ratio. Peripheral blood lactate kinetics may reflect immune cells activation and be useful for bedside monitoring.
