研究概要

靶向 HVEM 的 CAR-T 细胞可能对黑色素瘤的治疗有用。

研究思路结论见上方概要

几种嵌合抗原受体(CAR)T细胞已被用于治疗黑色素瘤,但未显示出良好的结果。本研究探讨了在黑色素瘤中过表达的疱疹病毒侵入介导因子(HVEM)是否是一种潜在的新型CAR-T 细胞治疗抗原。

开发并测试了一种CAR构建体,该构建体由用于识别HVEM的BTLA胞外域组成(BTLA-28z)。

转导BTLA-28z的Jurkat细胞与过表达HVEM的黑色素瘤细胞共孵育时,表现出增强的IL-2分泌。转导BTLA-28z的KHYG-1细胞也能裂解黑色素瘤细胞系。利用原代T细胞,我们制备了靶向HVEM的CAR-T 细胞。BTLA-28z CAR-T 细胞对黑色素瘤细胞系表现出优异的裂解活性。

A CAR construct, composed of the BTLA extracellular domain for HVEM recognition (BTLA-28z), was developed and tested.

Jurkat cells transduced with BTLA-28z exhibited enhanced IL-2 secretion when incubated with HVEM-over-expressing melanoma cells. KHYG-1 cells transduced with BTLA-28z also lysed melanoma cell lines. Using primary T cells, we generated CAR T cells targeting HVEM. BTLA-28z CAR T cells exhibited excellent lytic activities against melanoma cell lines.

HVEM-targeting CAR T cells may be useful for the treatment of melanoma.
