Tremendous advances in cell and gene therapy may soon realize the goal of treating and possibly curing HIV disease. These advances rely on new technologies for cell engineering and new strategies for product manufacturing that are targeting the most important immune deficits in HIV and promising to reconstitute protective, antiviral immunity and achieve natural suppression of HIV disease.
We summarize important advances in vectored passive immunity, e.g., directing in vivo expression of protective antibodies or antiviral proteins, B cell engineering to overcome the inadequate humoral immune response to HIV, and T cell engineering that is breaking new ground using viral vector modification of HIV specific T cells. These innovative approaches build on a substantial history of gene and cell therapy research in HIV disease.
Cell and gene therapy for HIV disease has been an area of tremendous innovation during the nearly two decades since early reports showed evidence for modulating disease. Recent efforts are building on the early experiences, closing gaps in previous approaches, and moving closer to effective treatment. Products approaching or already in clinical trials hold great promise for achieving durable suppression of HIV that will revolutionize therapy and offering hope to infected individuals that disease may be controlled without lifelong dependence on antiretroviral medications.
细胞和基因疗法的巨大进步可能很快实现治疗和可能治愈艾滋病的目标。这些进展依赖于细胞工程的新技术和产品制造的新策略,旨在针对艾滋病最重要的免疫缺陷,并有望重建保护性、抗病毒免疫,并实现艾滋病的自然抑制。
我们总结了被动免疫载体的重要进展,例如,指导保护性抗体或抗病毒蛋白的体内表达、克服对艾滋病病毒抗体反应不足的 B 细胞工程,以及使用艾滋病毒特异性 T 细胞的病毒载体修饰来开辟新天地的 T 细胞工程。这些创新方法建立在艾滋病病毒基因和细胞治疗研究的丰富历史基础上。
自早期报告表明可以调节疾病以来,近二十年来,艾滋病的细胞和基因治疗一直是一个极具创新性的领域。最近的努力是在早期经验的基础上进行的,弥补了以前方法的差距,并更接近有效的治疗。接近或已经进入临床试验的产品有望实现对艾滋病病毒的持久抑制,这将彻底改变治疗方法,并为感染个体带来希望,即无需终身依赖抗逆转录病毒药物即可控制疾病。
