免疫动态平衡是通过效应免疫细胞和调节性免疫细胞之间的精确平衡来维持的。免疫稳态的慢性偏离,在效应者与调节信号的比例增加的推动下,可促进炎症性疾病/状况(即自身免疫性疾病、移植排斥反应等)的发展和传播。目前治疗慢性炎症的方法依赖于全身给药的非特异性小分子,导致广泛的免疫抑制和不想要的副作用。因此,最近的研究已经开发出更局部和更特异的免疫调节方法,通过使用基于局部生物材料的递送系统来治疗炎症。特别是,这篇综述集中在(1)基于局部生物材料的递送系统,(2)用于聚合物递送系统的常用材料,以及(3)用于治疗炎症的新的免疫调节趋势,其特异性增加。
Immune homeostasis is maintained by a precise balance between effector immune cells and regulatory immune cells. Chronic deviations from immune homeostasis, driven by a greater ratio of effector to regulatory cues, can promote the development and propagation of inflammatory diseases/conditions (i.e., autoimmune diseases, transplant rejection, etc.). Current methods to treat chronic inflammation rely upon systemic administration of non-specific small molecules, resulting in broad immunosuppression with unwanted side effects. Consequently, recent studies have developed more localized and specific immunomodulatory approaches to treat inflammation through the use of local biomaterial-based delivery systems. In particular, this review focuses on (1) local biomaterial-based delivery systems, (2) common materials used for polymeric-delivery systems and (3) emerging immunomodulatory trends used to treat inflammation with increased specificity.
