神经病学中的 CAR-T 细胞疗法：神经肿瘤学、自身免疫性疾病与神经毒性的范围综述

Chimeric antigen receptor (CAR) T-cell therapy has been investigated in neurological diseases, encompassing both central nervous system malignancies and autoimmune disorders, thereby extending its application beyond hematological cancers. This scoping review evaluates CAR T-cell therapy applications in neurological conditions, assessing therapeutic efficacy, safety profiles, and neurotoxicity management strategies.

A literature search across four databases (January 2020-December 2025) identified 33 studies meeting the inclusion criteria, encompassing original and secondary research from international centers. CAR T-cell therapy demonstrated promising efficacy across diverse neurological conditions. In glioblastoma trials, 44% of patients (n = 128) achieved partial or complete clinical/radiographic responses with favorable safety profiles.

Moreover, compelling results emerged from neuromyelitis optica spectrum disorder studies, in which 92% of patients (11/12) achieved sustained relapse-free remission over a median follow-up of 5. 5 months. Multiple sclerosis, myasthenia gravis, and stiff-person syndrome cases exhibited excellent treatment tolerance without significant immune effector cell-associated neurotoxicity syndrome (ICANS), which is a major concern affecting 27% of patients with hematological malignancies.

Overall, CAR T-cell therapy emerges as a novel therapeutic strategy in neurology, encompassing both oncological and autoimmune conditions. Toxicity profiles in neurological CAR T-cell applications differ substantially from those observed in hematologic malignancies, underscoring the need for condition-specific risk assessment frameworks and customized management approaches. Future research should prioritize larger multicenter trials with extended follow-up to establish definitive efficacy and safety profiles in neurological indications.
