人类有许多慢性病，像多发性硬化症、I型糖尿病和类风湿性关节炎，是由免疫系统以某种方式“滥杀无辜”引起的，这种免疫系统伤害自身组织和器官的疾病被称为自体免疫疾病。目前，自体免疫疾病尚无法治愈，而现有的多数药物则无法区分正常免疫细胞和会发动自体攻击的免疫细胞，所以它们虽然可暂时缓解症状，但也消灭了抑制有害细菌和病毒所必需的正常免疫细胞，从长期看会让病人更脆弱。
研究负责人、美国国家卫生研究院黏膜免疫研究室主任陈万军对新华社记者说，自体免疫疾病的一个共同的重要发病机理是，患者免疫系统的正常平衡被破坏，导致患者体内充斥着大量炎症细胞和因子。所以理论上zui有效的治疗方法应该是，首先把这个已失去平衡、免疫反应过强的状态打破，然后再重新诱导免疫系统建立一个新的秩序，即恢复正常的平衡状态，让免疫细胞对自己的组织和器官耐受而不是破坏。“简单地说，基本原理就是‘打破一个旧世界，建立一个新世界’”。
陈万军等人采取的新方案是，首先诱导实验鼠的自身免疫细胞凋亡，让这些细胞被体内一种叫做巨噬细胞的吞噬细胞“吃掉”，之后巨噬细胞会产生一种重要的免疫调控抑制因子TGFβ。TGFβ在体内会形成一个免疫调控的微环境，在这种微环境下再注射一种蛋白多肽，去刺激新的未分化的“原始”或“处女”T细胞，这些T细胞在TGFβ占优势的微环境中，会分化成免疫调节T细胞，而不是破坏自身组织和器官的炎症细胞。
他说：“这些免疫调节细胞会进入相应的、有自身免疫病的组织和器官，防止和抑制破坏自身组织的免疫炎症细胞的产生或发挥功能，从而让疾病得到缓解甚至治愈。”

There are many chronic diseases in humans, such as multiple sclerosis, type I diabetes and rheumatoid arthritis, which are caused by the immune system somehow "killing innocent people" and diseases of the immune system that harm their own tissues and organs are said For autoimmune diseases. At present, autoimmune diseases are not yet curable, and most existing drugs can not distinguish between normal immune cells and autoimmune immune cells, so although they can temporarily relieve symptoms, but also eliminate the necessary to inhibit harmful bacteria and viruses Normal immune cells, in the long run will make the patient more vulnerable.
Chen Wanjun, head of the study and Director of the Mucosal Immunization Laboratory at the National Institutes of Health, told Xinhua that a common and important pathogenesis of autoimmune diseases is the breakdown of the normal balance of the patient's immune system, resulting in the patient being flooded with inflammatory cells And factor. Therefore, in theory, the most effective treatment should be the first to break the balance of the immune response is too strong, and then re-induce the immune system to establish a new order, that is, to restore normal equilibrium, so that immune cells on their own Tissue and organs are tolerant rather than destructive. "Simply put, the basic principle is to 'break an old world and build a new world'".
Chen Wanjun and others to take a new program is to first induce experimental mouse immune cell apoptosis, so that these cells are the body of a phagocyte called macrophage eaten, macrophages will produce an important immune Regulatory inhibitor of TGFβ. TGFβ forms an immunomodulatory microenvironment in the body in which a protein polypeptide is reinjected to stimulate new undifferentiated "virgin" or "virgin" T cells that predominate in TGFβ In the microenvironment, it differentiates into immunoregulatory T cells rather than inflammatory cells that destroy their own tissues and organs.
"These immune-regulating cells get into the corresponding autoimmune-damaged tissues and organs, preventing and inhibiting the production or functioning of immune-inflammatory cells that destroy their tissues, thereby allowing the disease to be relieved or even healed."
