基于 mRNA 的黑色素瘤疫苗进展：脂质纳米颗粒与树突状细胞递送平台的叙述性综述

Melanoma remains one of the deadliest cutaneous malignancies worldwide, and despite advances in systemic therapy, recurrence and treatment resistance remain frequent challenges. Following the success of COVID-19 mRNA vaccines, mRNA-based cancer vaccines targeting melanoma antigens have emerged as a promising therapeutic direction. This review summarizes current evidence on mRNA melanoma vaccines, focusing on two leading delivery platforms: lipid nanoparticles (LNPs) and dendritic cell (DC) vaccines.

A comprehensive search of MEDLINE, Embase, and Scopus from 2015 to 2025 identified clinical trials, preclinical studies, and review articles evaluating mRNA vaccine constructs and delivery strategies. Completed clinical studies demonstrate that personalized LNP-formulated mRNA vaccines can enhance neoantigen-specific T-cell responses and improve recurrence-free survival, particularly when combined with immune checkpoint inhibitors.

DC-based mRNA vaccines also show potent immunogenicity, with stronger responses observed when DC maturation is optimized. Ongoing trials continue to investigate next-generation LNP formulations, DC priming strategies, and personalized neoantigen approaches.

Overall, current evidence indicates that both LNP and DC platforms can augment antitumor immunity by broadening T-cell responses and enhancing checkpoint inhibition. Continued refinement of delivery vehicles, neoantigen selection, and scalable manufacturing processes will be essential to realizing the full clinical potential of mRNA vaccines in melanoma.
