<strong>[[嵌合抗原受体T细胞疗法]]([[CAR-T]])</strong>是一种通过基因工程技术改造患者自身<strong>[[T细胞]]</strong>，使其表达<strong>[[嵌合抗原受体]]([[CAR]])</strong>，从而精准识别并杀伤肿瘤细胞的个体化<strong>[[细胞免疫治疗]]</strong>。作为2026年生物医药领域的“活的药物”，[[CAR-T]]已在<strong>[[B细胞恶性肿瘤]]</strong>及<strong>[[多发性骨髓瘤]]</strong>的治疗中取得了革命性突破。随着<strong>[[第四代CAR-T]]</strong>及<strong>[[通用型CAR-T]]([[UCAR-T]])</strong>技术的成熟，该疗法正从末线挽救向一线治疗推进，并开始在<strong>[[自身免疫性疾病]]</strong>（如[[SLE]]）领域展现出根治潜力。<br />

<br />
<ul style="padding-left: 25px; color: #334155;"><br />
<li style="margin-bottom: 12px;"><strong>结构组成：</strong><br />
<br>[[CAR]]分子由胞外抗原结合域(通常为<strong>[[scFv]]</strong>)、跨膜区及胞内信号域(如<strong>[[CD3ζ]]</strong>和共刺激域<strong>[[4-1BB]]</strong>或<strong>[[CD28]]</strong>)组成。2026年的前沿设计还加入了细胞因子表达模块。</li><br />
<li style="margin-bottom: 12px;"><strong>识别与激活：</strong><br />
<br>[[scFv]]直接结合肿瘤表面抗原(如[[CD19]])，触发胞内信号级联反应，诱导[[CAR-T]]细胞大量增殖并释放<strong>[[穿孔素]]</strong>、<strong>[[颗粒酶]]</strong>，实现靶向裂解。</li><br />
<li style="margin-bottom: 12px;"><strong>记忆与存续：</strong><br />
<br>回输后的[[CAR-T]]细胞可在体内形成免疫记忆。2026年临床数据显示，部分淋巴瘤患者在回输10年后体内仍能检测到活性[[CAR-T]]细胞。</li><br />

<li style="margin-bottom: 12px;"><strong>全流程管理：</strong>单采(Apheresis)→体外扩增(Expansion)→清淋化疗(Lymphodepletion)→回输(Infusion)。2026年<strong>[[快速生产工艺]]</strong>已将交付期缩短至7-10天。</li><br />
<li style="margin-bottom: 12px;"><strong>[[细胞因子释放综合征]]([[CRS]])管理：</strong>2026共识要求在回输后密切监测发热及循环指标，首选<strong>[[托珠单抗]]</strong>联合皮质激素进行干预。</li><br />
<li style="margin-bottom: 12px;"><strong>[[ICANS]]([[神经毒性]])预警：</strong>表现为失语、意识模糊。2026规范建议早期使用大剂量激素，并强调通过动态脑电图进行风险分层。</li><br />
