神经节苷脂是一类位于几乎所有细胞质膜上的鞘糖脂,在细胞信号传导和脂筏动力学中起着至关重要的作用。
神经节苷脂是一类位于几乎所有细胞质膜上的鞘糖脂,在细胞信号传导和脂筏动力学中发挥关键作用。其在胚胎发育期间表达显著升高,在大多数成人组织中明显降低,但在多种肿瘤组织中显著升高。这种独特的表达模式凸显了神经节苷脂作为有前景的治疗靶点,因为它们在肿瘤进展、转移和治疗耐药中发挥作用。靶向神经节苷脂的治疗,特别是针对 GD2 的单克隆抗体,已显示出临床获益。Dinutuximab 已获批用于高危神经母细胞瘤,与细胞因子联合使用时,相比单纯标准治疗改善了无事件生存期(NCT00026312)。同样,Naxitamab 与 GM-CSF 联合使用,在复发/难治性神经母细胞瘤中达到了总体缓解率(NCT03363373)。除抗体外,新兴的 GD2 靶向细胞免疫治疗,包括 CAR-T 细胞方法,已在难治性神经母细胞瘤和肉瘤中显示出有前景的早期临床反应,突显了其转化潜力。此外,Racotumomab(抗 NeuGcGM3)在晚期非小细胞肺癌中显示出生存获益,相比安慰剂延长了中位总生存期(NCT01240447)。尽管取得了这些进展,在改善患者选择、减少脱靶毒性如神经病理性疼痛以及应对耐药机制方面仍存在挑战。本综述探讨了神经节苷脂介导的癌症治疗的最新进展,强调当前临床结局,突出对更精准靶向方法的需求,并探索合理的联合策略以提高治疗疗效。
Gangliosides, a class of glycosphingolipids located on the plasma membrane of nearly all cells, play a crucial role in cell signaling and lipid raft dynamics. Their expression is notably high during embryonic development, markedly reduced in most adult tissues, but significantly elevated in various tumor tissues. This distinct expression pattern highlights gangliosides as promising therapeutic targets due to their roles in tumor progression, metastasis, and therapeutic resistance. Targeted ganglioside therapies, particularly monoclonal antibodies against GD2, have already demonstrated clinical benefit. Dinutuximab, approved for high-risk neuroblastoma, improved event-free survival when combined with cytokines with standard therapy alone (NCT00026312). Similarly, Naxitamab, in combination with GM-CSF, achieved an overall response rate in relapsed/refractory neuroblastoma (NCT03363373). Beyond antibodies, emerging GD2-targeted cellular immunotherapies, including CAR-T cell approaches, have shown promising early-phase clinical responses in refractory neuroblastoma and sarcomas, underscoring their translational potential. Additionally, Racotumomab (anti-NeuGcGM3) demonstrated a survival benefit in advanced non-small cell lung cancer, extending median overall survival compared to placebo (NCT01240447). Despite these advances, challenges remain in improving patient selection, reducing off-target toxicities such as neuropathic pain, and addressing resistance mechanisms. This review examines the latest developments in ganglioside-mediated cancer therapy, emphasizing current clinical outcomes, highlighting the need for more precise targeting approaches, and exploring rational combination strategies to enhance therapeutic efficacy.
