现代免疫学的发展使人们逐渐认识到:在免疫反应中,不仅有淋巴细胞的参与,还有一类细胞也能接受抗原信息,并影响淋巴细胞的增殖、分化、进而起着免疫的调节作用。这类细胞除了为人们所公认的巨噬细胞外,可能还包括两种网状细胞,即树突样网状细胞和指突样网状细胞。树突样网状细胞早已为人们所认识,它主要地特异定位于淋巴组织的B细胞区,其功能多认为能保留抗原或免疫复合物,与生发中心的形成有关,而指突样网状细胞只是近年才为人们所重视。 The development of modern immunology makes people come to realize that: In the immune response, not only lymphocytes involved, there is also a class of cells can accept antigen information and affect lymphocyte proliferation, differentiation, and thus play a regulatory role in the immune. In addition to these types of cells known macrophages, may also include two kinds of reticular cells, namely, dendritic reticulocyte and reticulocyte. Dendritic-like reticulocytes have long been known, and are predominantly located specifically in the B-cell region of lymphoid tissue, which is thought to retain antigen or immune complexes and is associated with the formation of germinal centers, whereas the reticulocyte Cells only pay attention to people in recent years.
