    <p style="margin: 15px 0; text-align: justify;">
        <strong>[[Telisotuzumab]]</strong>结合了抗体的特异性与化疗药物的强效杀伤力，其药理过程分为三个核心阶段：
    </p>
    <ul style="padding-left: 25px; color: #334155;">
        <li style="margin-bottom: 12px;">受体识别与内吞：抗体部分特异性结合肿瘤细胞表面的<strong>[[c-MET]]</strong>受体。<strong>[[c-MET]]</strong>作为一种受体酪氨酸激酶，在正常组织中表达受限，但在肺癌细胞中常因<strong>[[MET扩增]]</strong>或蛋白过表达而大量存在。结合后，<strong>[[ADC]]</strong>复合物通过受体介导的<strong>[[内吞作用]]</strong>进入溶酶体。</li>
        <li style="margin-bottom: 12px;">载荷特异性释放：在溶酶体酸性环境及蛋白酶作用下，缬氨酸-瓜氨酸接头被剪切，释放出高活性的<strong>[[MMAE]]</strong>。</li>
        <li style="margin-bottom: 12px;">微管阻断与凋亡：释放出的<strong>[[MMAE]]</strong>结合细胞内的<strong>[[微管蛋白]]</strong>，抑制其聚合，导致细胞周期阻滞在G2/M期，最终诱导肿瘤细胞发生<strong>[[凋亡]]</strong>。</li>
    </ul>

    </p>
    <ul style="padding-left: 25px; color: #334155;">
        <li style="margin-bottom: 12px;">精准筛选标志物：由于疗效与<strong>[[c-MET]]</strong>表达水平高度正相关，临床上必须通过<strong>[[免疫组化]]</strong>（IHC）检测患者的蛋白表达强度，而非仅依赖<strong>[[NGS]]</strong>检测基因扩增。</li>

        <li style="margin-bottom: 12px;">神经毒性预警：鉴于<strong>[[MMAE]]</strong>载荷的特征，治疗期间需定期评估患者肢体末梢感觉。若出现2级及以上<strong>[[周围神经病变]]</strong>，需考虑减量或暂停给药。</li>
