<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">引言</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">实体瘤细胞疗法,一个在癌症治疗<span style="color: black;">行业</span>内<span style="color: black;">导致</span>广泛关注的概念,其历史<span style="color: black;">能够</span>追溯到几十年前。最初,<span style="color: black;">专家</span>们仅能<span style="color: black;">经过</span>传统的手段,如手术、放疗和化疗来对抗癌症。然而,随着科学技术的<span style="color: black;">持续</span>进步,人们<span style="color: black;">起始</span>探索更为<span style="color: black;">精细</span>和个性化的治疗<span style="color: black;">办法</span>,<span style="color: black;">尤其</span>是针对<span style="color: black;">哪些</span>难以<span style="color: black;">经过</span>传统方式治疗的实体瘤。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">实体瘤与血液肿瘤的<span style="color: black;">重点</span>区别在于,实体瘤<span style="color: black;">是由于</span>固体组织中的<span style="color: black;">反常</span>细胞增生形成的肿块,如乳腺癌、肺癌等,而血液肿瘤则<span style="color: black;">触及</span>血液和骨髓中的癌细胞,如白血病</strong>。<span style="color: black;">长时间</span><span style="color: black;">败兴</span>,血液肿瘤因其在血液中的流动性质而更易于<span style="color: black;">经过</span>免疫细胞进行治疗。相比之下,<strong style="color: blue;">实体瘤的治疗因其<span style="color: black;">繁杂</span>的微环境和免疫逃避机制而面临更大的挑战</strong>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">随着免疫疗法的发展,<span style="color: black;">尤其</span>是肿瘤浸润性淋巴细胞(TIL, tumour-infiltrating lymphocytes)技术的<span style="color: black;">显现</span>,实体瘤治疗迎来了新的曙光。这种疗法<strong style="color: blue;">利用<span style="color: black;">病人</span><span style="color: black;">自己</span>的免疫系统来识别和攻击癌细胞,<span style="color: black;">尤其</span>是<span style="color: black;">哪些</span><span style="color: black;">已然</span>渗透到肿瘤中的特定免疫细胞</strong>。经过数十年的<span style="color: black;">科研</span>和临床<span style="color: black;">实验</span>,TIL疗法<span style="color: black;">最终</span>在近年来<span style="color: black;">得到</span>了美国食品和<span style="color: black;">药品</span>管理局(FDA)的<span style="color: black;">准许</span>,标志着实体瘤细胞疗法的重大突破。(3月11日<strong style="color: blue;">Nature</strong> “<strong style="color: blue;">First cell therapy for solid tumours heads to the clinic: what it means for cancer treatment</strong>”)</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">突破性疗法:肿瘤浸润性淋巴细胞(TIL)</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肿瘤浸润性淋巴细胞(TIL)的概念最早由Steven Rosenberg教授及其团队在20世纪80年代提出。Rosenberg教授是一位在癌症<span style="color: black;">科研</span>和治疗<span style="color: black;">行业</span>内享有盛誉的<span style="color: black;">专家</span>,他认为,<strong style="color: blue;">肿瘤微环境中的淋巴细胞,即TIL,<span style="color: black;">拥有</span>针对癌细胞的自然识别和攻击能力。<span style="color: black;">经过</span>提取、扩增并重新注入这些细胞,<span style="color: black;">能够</span><span style="color: black;">极重</span>地<span style="color: black;">加强</span><span style="color: black;">病人</span>的免疫反应,从而攻击并消灭肿瘤细胞。</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">TIL疗法的治疗机制基于对肿瘤微环境的深入理解以及免疫细胞的<span style="color: black;">精细</span>操控。在经<span style="color: black;">太多</span>年的<span style="color: black;">基本</span><span style="color: black;">科研</span>和临床实验后,这一疗法已展现出对多种实体瘤,尤其是黑色素瘤等难治性癌症的<span style="color: black;">明显</span>疗效。Rosenberg教授和他的团队在TIL疗法的<span style="color: black;">研发</span>和应用中所作出的贡献,为成千上万的癌症<span style="color: black;">病人</span>带来了新的<span style="color: black;">期盼</span>和可能性。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">从实体瘤中提取和培养TIL</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肿瘤浸润性淋巴细胞(TIL)疗法的核心在于利用<span style="color: black;">病人</span><span style="color: black;">自己</span>的免疫系统对抗癌症。此过程<span style="color: black;">触及</span>两个<span style="color: black;">重要</span><span style="color: black;">过程</span>:<span style="color: black;">首要</span>是从实体瘤中提取TIL,其次是在实验室中培养和扩增这些细胞。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">手术移除肿瘤和实验室处理</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">TIL的提取始于手术切除<span style="color: black;">病人</span>的肿瘤组织。这一<span style="color: black;">过程</span><span style="color: black;">需求</span>高度的精确性和技术专长,以确保<span style="color: black;">得到</span>足够的肿瘤样本,<span style="color: black;">同期</span><span style="color: black;">尽可能</span>减少对<span style="color: black;">病人</span>的创伤。手术后,肿瘤组织被立即送至实验室进行处理。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在实验室中,实验人员<span style="color: black;">首要</span>对肿瘤样本进行细致的分解,分离出渗透在肿瘤中的淋巴细胞。这些细胞即为TIL,它们<span style="color: black;">拥有</span>直接识别并攻击癌细胞的能力。分离过程<span style="color: black;">必须</span>在<span style="color: black;">没</span>菌<span style="color: black;">前提</span>下进行,以防微生物污染,<span style="color: black;">保证</span>TIL的纯度和活性。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">TIL培养扩增的<span style="color: black;">重要</span>技术</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">一旦成功分离,TIL就会被转移到特定的培养基中,<span style="color: black;">起始</span>扩增过程。这一过程可能<span style="color: black;">必须</span><span style="color: black;">几周</span>时间,<span style="color: black;">时期</span><span style="color: black;">必须</span>细心<span style="color: black;">调节</span>培养<span style="color: black;">前提</span>,如温度、气体<span style="color: black;">构成</span>和培养基营养物质,以优化TIL的增长和活性。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">扩增的TIL经过严格的质量<span style="color: black;">掌控</span>测试,以<span style="color: black;">保证</span>它们的安全性和有效性。<span style="color: black;">仅有</span><span style="color: black;">哪些</span><span style="color: black;">经过</span>测试的细胞才会被用于后续的治疗过程。这一<span style="color: black;">周期</span>的成功<span style="color: black;">重要</span>在于实验人员的专业知识和经验,<span style="color: black;">她们</span><span style="color: black;">必要</span>精确<span style="color: black;">掌控</span>培养<span style="color: black;">前提</span>,<span style="color: black;">同期</span>对TIL的生长状态进行仔细监测。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">TIL疗法与CAR-T疗法有何不同?</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">TIL疗法与CAR-T疗法都是免疫细胞疗法的<span style="color: black;">要紧</span><span style="color: black;">构成</span>部分,但两者在治疗机制、应用范围和生产过程等方面存在<span style="color: black;">显著</span>差异。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">-治疗机制:TIL疗法<span style="color: black;">经过</span>提取、培养和扩增<span style="color: black;">病人</span>肿瘤内的自然存在的淋巴细胞,<span style="color: black;">而后</span>将这些细胞输回<span style="color: black;">病人</span><span style="color: black;">身体</span>以攻击癌细胞。而CAR-T疗法则是<span style="color: black;">经过</span>遗传工程修改<span style="color: black;">病人</span>的T细胞,使其表达特定的嵌合抗原受体(CAR),这些受体能够特异性识别并杀死癌细胞。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">-应用范围:CAR-T疗法<span style="color: black;">日前</span><span style="color: black;">重点</span>应用于某些类型的血液癌症治疗,如急性淋巴细胞性白血病(ALL)和非霍奇金淋巴瘤(NHL)。TIL疗法则<span style="color: black;">重点</span>针对实体瘤,尤其是<span style="color: black;">哪些</span>对传统治疗<span style="color: black;">办法</span>反应不佳的晚期实体瘤<span style="color: black;">病人</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">-生产过程:CAR-T疗法的生产<span style="color: black;">必须</span>对T细胞进行遗传改造,这一过程技术<span style="color: black;">需求</span>高,成本较高。而TIL疗法虽然<span style="color: black;">一样</span><span style="color: black;">必须</span>细胞培养和扩增,但<span style="color: black;">日前</span>不<span style="color: black;">触及</span>遗传改造,技术流程相对简单。</p>
