<strong>个性化新抗原疫苗</strong>（Personalized Neoantigen Vaccine）是一种基于肿瘤个体化突变信息定制的精准免疫疗法。<strong>[[新抗原]]</strong>（Neoantigen）是指由肿瘤细胞基因突变产生的、仅表达于肿瘤组织而不在正常组织表达的蛋白质片段。由于这些抗原未经胸腺免疫耐受筛选，具有极强的 <strong>[[免疫原性]]</strong>。个性化疫苗通过鉴定患者特有的“非我”（Non-self）突变，利用 <strong>[[mRNA]]</strong>、<strong>[[多肽]]</strong> 或 <strong>[[DNA]]</strong> 载体激发机体产生针对性 <strong>[[CD8+ T细胞]]</strong> 反应。这种“一人一药”的范式是目前解决 <strong>[[肿瘤异质性]]</strong> 和实现长期免疫监视的前沿路径，尤其在与 <strong>[[PD-1抗体]]</strong> 联合使用时展现出显著的协同临床获益。<br />

<li style="margin-bottom: 12px;"><strong>[[mRNA-4157]] (V940)：</strong> Moderna 研发的 mRNA 疫苗。在 <strong>KEYNOTE-942</strong> 研究中，其联合帕博利珠单抗治疗黑色素瘤，相比单用 K 药显著降低了 44% 的复发或死亡风险。</li><br />
<li style="margin-bottom: 12px;"><strong>胰腺癌突破：</strong> BioNTech 的研究证明，在手术切除后的 <strong>[[胰腺癌]]</strong> 患者中，疫苗能诱导高水平的新抗原特异性 T 细胞，且与患者的长期无复发生存显著相关。</li><br />
<li style="margin-bottom: 12px;"><strong>攻克“冷肿瘤”：</strong> 疫苗能将缺乏免疫细胞浸润的“冷肿瘤”转化为“热肿瘤”，为不响应 PD-1 的患者（如 <strong>[[MSS型肠癌]]</strong>）提供新的机会。</li><br />

个性化新抗原疫苗标志着从“通用型药物”向“数字生命化疗法”的飞跃。目前的瓶颈在于 <strong>预测算法的准确度</strong>（仅约 10% 的预测位点能诱发 T 细胞反应）以及 <strong>生产成本与周期的压缩</strong>。未来，结合 <strong>[[AI/蛋白质折叠预测]]</strong> 及 <strong>[[原位免疫启动]]</strong> 技术，新抗原疫苗有望成为术后清除 <strong>[[MRD]]</strong>、实现癌症临床治愈的关键拼图。<br />
