反应性淋巴结中的边缘区:van denOord,JJ 边缘区(Mz)在脾脏中研究最多,但淋巴结中Mz至今仍带有神秘性。从免疫反应主要规律的观点来看,推测MZLs也存在于其他淋巴组织。应用标志搜寻,在人肠中,中等大小类似脾脏中MZLs的淋巴组织,在集合淋巴滤泡周围形成一个阔的带,并延伸到顶部,浸润到覆盖的上皮,这些细胞有C_3b和C_3d受体,表达IgM,但不表达IgD。在淋巴 Marginal region in reactive lymph nodes: van denOord, JJ Marginal region (Mz) is the most studied in the spleen, but Mz in lymph nodes is still mysterious. From the point of view of the main rules of immune response, it is speculated that MZLs are also present in other lymphoid tissues. Using a marker search, in the human gut, medium-sized lymphoid tissues resembling MZLs in the spleen form a broad band around the collecting lymphoid follicles and extend to the top to infiltrate the covered epithelium with C3b and C3d receptors. It expresses IgM but does not express IgD. Lymph
