            <strong>[[Idecabtagene vicleucel]]</strong>（简称<strong>[[Ide-cel]]</strong>），商品名为<strong>[[Abecma]]</strong>，是一种针对<strong>[[B细胞成熟抗原]]</strong>（<strong>[[BCMA]]</strong>）的自体<strong>[[CAR-T]]</strong>（嵌合抗原受体T细胞）疗法。作为全球首个获批用于治疗<strong>[[多发性骨髓瘤]]</strong>的<strong>[[CAR-T]]</strong>产品，它通过基因工程手段使患者自身的<strong>[[T细胞]]</strong>表达能识别<strong>[[BCMA]]</strong>的嵌合抗原受体。<strong>[[Ide-cel]]</strong>包含一个抗<strong>[[BCMA]]</strong>的单链抗体片段（scFv）、<strong>[[4-1BB]]</strong>共刺激结构域以及<strong>[[CD3ζ]]</strong>激活结构域。该疗法主要用于治疗既往接受过包括免疫调节剂、蛋白酶体抑制剂和抗<strong>[[CD38]]</strong>单抗在内的至少三线治疗失败的复发或难治性<strong>[[多发性骨髓瘤]]</strong>（RRMM）成年患者，开创了骨髓瘤<strong>[[免疫治疗]]</strong>的新纪元。

        <strong>[[Idecabtagene vicleucel]]</strong>通过将患者的<strong>[[T细胞]]</strong>转化为精准打击肿瘤的“活药”，其药理过程包括：
    </p>
    <ul style="padding-left: 25px; color: #334155;">
        <li style="margin-bottom: 12px;">靶向识别：CAR结构中的scFv片段能够特异性结合浆细胞表面的<strong>[[BCMA]]</strong>抗原。<strong>[[BCMA]]</strong>在正常组织中几乎不表达，但在恶性浆细胞中广泛存在，确保了治疗的靶向性。</li>
        <li style="margin-bottom: 12px;">级联激活：一旦结合靶点，<strong>[[CD3ζ]]</strong>激活域启动第一信号，随后<strong>[[4-1BB]]</strong>结构域提供强力的共刺激信号，诱导<strong>[[CAR-T]]</strong>细胞在体内迅速扩增并活化。</li>
        <li style="margin-bottom: 12px;">细胞毒杀伤：活化的<strong>[[CAR-T]]</strong>细胞释放<strong>[[穿孔素]]</strong>和<strong>[[颗粒酶]]</strong>，诱导肿瘤细胞<strong>[[凋亡]]</strong>，并分泌细胞因子（如干扰素-γ）增强局部抗肿瘤免疫应答。</li>
