The role of splenic lymphoid dendritic cells (DC) and macrophages (M phi) from mice in induction of immune responses in vivo has been investigated. Varying numbers of purified DC and M phi pulsed in vitro with tobacco mosaic virus (TMV) or with rabbit antiidiotypic antibodies (Ab2) directed against a private rabbit anti-TMV idiotype were injected back into syngeneic mice. In both systems, DC appeared to strongly enhance the primary and secondary responses to the virus. Optimal responses were obtained with 5 X 10(4) purified DC carrying TMV or rabbit Ab2. In contrast, M phi were less efficient by a factor of at least 100. These results show the potency of lymphoid DC as inducing cells in T-dependent antibody responses in vivo.
已经研究了来自小鼠的脾淋巴样树突状细胞(DC)和巨噬细胞(M phi)在体内诱导免疫反应中的作用。将不同数量的体外用烟草花叶病毒(TMV)或针对一种兔抗TMV独特型的兔抗独特型抗体(Ab2)脉冲处理的纯化DC和M phi回注到同基因小鼠体内。在这两个系统中,DC似乎都能强烈增强对该病毒的初次和二次反应。用携带TMV或兔Ab2的5×10⁴个纯化DC可获得最佳反应。相比之下,M phi的效率至少低100倍。这些结果表明淋巴样DC作为体内T细胞依赖性抗体反应中的诱导细胞的效力。
