摘要: 红细胞在机体内含量丰富,主要功能是运输氧气。成熟哺乳动物红细胞无细胞核和细胞器,且比表面积大、易于修饰,是理想的递送载体,已被广泛用于药物递送。红细胞还具有免疫调节功能。红细胞能够结合循环中的病原体并与趋化因子相互作用参与固有免疫应答。衰老的红细胞通过调节膜表面分子的表达,与脾脏中的吞噬细胞相互作用,从而调节适应性免疫应答,使衰老红细胞最终以非炎症途径被清除。基于红细胞在递送和免疫调节方面的优势,红细胞载体开始用于新型疫苗中传统疫苗佐剂的替代。基于红细胞载体的合成方法多样,生物安全性良好且易于修饰,能够满足不同疫苗的需求。处于不同阶段的红细胞载体通过设计能够发挥不同的免疫调节功能。基于正常红细胞的载体能够诱导免疫激活,而基于衰老红细胞的载体可用于诱导免疫耐受,在肿瘤、传染病、自身免疫性疾病的预防和治疗中均有良好效果。本文从红细胞作为疫苗载体的生物学优势、基于红细胞的疫苗载体与抗原的作用形式及其免疫效果、红细胞载体的优化策略等方面进行综述,为新型疫苗的研发提供方向。

Abstract: Erythrocytes are abundant within the body and are predominantly responsible for oxygen delivery. Mature mammalian erythrocytes have no nucleus and organelles, and they possess a high surface area-to-volume ratio, making them easy to conduct modification. These characteristics make erythrocytes suitable as delivery system, and erythrocytes have been used for drug delivery. Erythrocytes also possess immune regulatory capabilities. Erythrocytes can bind to pathogens and interact with chemokines, participating in innate immunity. Senescent erythrocytes modulate the expression of surface molecules and interact with phagocytic cells in the spleen, thereby regulating the adaptive immune response, facilitating the clearance of senescent erythrocytes through non-inflammatory pathways. The advantages in delivery and immunomodulation have led to the use of erythrocyte-based carriers in novel vaccines, replacing traditional vaccine adjuvants. There are diverse methods for synthesis of erythrocyte-based carriers. These carriers have great biocompatibility and are amenable to modification, accommodating the needs of different vaccines. By design, carriers based on erythrocytes in different stages can exert different immunomodulatory functions. Carriers based on normal erythrocytes can induce immune activation, while those based on senescent erythrocytes can be used to induce immune tolerance, showing promising results in the prevention and treatment of cancer, infectious diseases and autoimmune diseases. This article reviews the biological advantages of erythrocyte as vaccine carriers, antigen-loading strategies, the immunological effects of erythrocyte-based vaccine carriers and optimization strategies, providing insights for the development of novel vaccines.
