C57BL/6 (B6) mice infected with LP-BM5 retroviruses develop disease, including an immunodeficiency similar to AIDS. This disease, murine AIDS (MAIDS), is inhibited by in vivo anti-CD154 monoclonal antibody treatment. The similar levels of insusceptibility of CD40(-/-) and CD154(-/-) B6 mice indicate that CD154/CD40 molecular interactions are required for MAIDS. CD4(+) T and B cells, respectively, provide the CD154 and CD40 expression needed for MAIDS induction. Here, the required CD154/CD40 interaction is shown to be independent of CD80 and CD86 expression: CD80/CD86(-/-) B6 mice develop MAIDS after LP-BM5 infection.
感染LP - BM5逆转录病毒的C57BL/6(B6)小鼠会发病,包括出现一种类似于艾滋病的免疫缺陷。这种疾病,即鼠类艾滋病(MAIDS),可通过体内抗CD154单克隆抗体治疗得到抑制。CD40(-/-)和CD154(-/-)B6小鼠的不敏感性水平相似,这表明MAIDS需要CD154/CD40分子相互作用。CD4(+)T细胞和B细胞分别提供MAIDS诱导所需的CD154和CD40表达。在此,已表明所需的CD154/CD40相互作用独立于CD80和CD86表达:CD80/CD86(-/-)B6小鼠在感染LP - BM5后会患上MAIDS。
