Since the original proposal by Fearon and Locksley (Fearon and Locksley. 1996. Science 272: 50-53) that the complement system linked innate and adaptive immunity, there has been a rapid expansion of studies on this topic. With the advance of intravital imaging, a number of recent papers revealed an additional novel pathway in which complement C3 and its receptors enhance humoral immunity through delivery of Ag to the B cell compartment. In this review, we discuss this pathway and highlight several novel exceptions recently found with a model influenza vaccine, such as mannose-binding lectin opsonization of influenza and uptake by macrophages, and the capture of virus by dendritic cells residing in the medullary compartment of peripheral lymph nodes.
自 Fearon 和 Locksley(Fearon 和 Locksley。1996. Science 272: 50-53)最初提出补体系统将先天免疫和适应性免疫联系起来以来,针对这一主题的研究迅速扩展。随着活体成像技术的进步,最近的一些论文揭示了补体 C3 及其受体通过将 Ag 递送至 B 细胞区室来增强体液免疫的另一种新途径。在这篇综述中,我们讨论了这一途径,并强调了最近在流感疫苗模型中发现的几个新的例外情况,例如流感的甘露糖结合凝集素调理作用和被巨噬细胞摄取,以及驻留在周围淋巴结髓质区室中的树突状细胞捕获病毒。
