    <p style="margin: 15px 0; text-align: justify;">
        [[优捷妥]]的作用机制聚焦于免疫应答的早期启动阶段，通过解除T细胞活化的限制性“刹车”来动员免疫系统。
    </p>
    
    <ul style="padding-left: 25px; color: #334155;">
        <li style="margin-bottom: 12px;"><strong>启动阶段活化：</strong>
            [[CTLA-4]]在初始T细胞激活时表达，通过与[[B7]]高亲和力结合来抑制T细胞扩增。[[优捷妥]]竞争性阻断该路径，使[[CD28]]激活性信号占据主导，促进效应T细胞的大规模增殖。</li>
        <li style="margin-bottom: 12px;"><strong>IgG2 骨架优势：</strong>
            与[[IgG1]]型的[[伊匹木单抗]]不同，[[优捷妥]]采用[[IgG2]]亚型，在阻断受体的同时几乎不介导抗体依赖性细胞毒性（[[ADCC]]），减少了对活化T细胞的直接杀伤，从而更温和地启动免疫反应。</li>
        <li style="margin-bottom: 12px;"><strong>STRIDE 动力学：</strong>
            2026年药理研究证实，单次高剂量[[优捷妥]]（[[300mg]]）能产生“免疫冲击”，在诱导充足的克隆多样性后，由[[度伐利尤单抗]]接力维持，实现了强效与耐受性的平衡。</li>
