Fig. 1.携带人外周血单个核细胞移植物(hu-PBL-SCID)的严重混合免疫缺陷小鼠感染不同株HIV-1或HIV-2后,人CD4 T细胞的耗竭。左图显示了来自分子克隆的五种不同HIV-1 c,r HIV-2 IUC1)病毒的感染。通过注射无细胞病毒完成感染。右图为单独的实验,其中hu-PBL-SCID小鼠用无细胞病毒(无SF 33和无SF 162)或1 × 10感染的hu-PBL(SF 33-细胞和SF 162-细胞)感染。在感染后,,周,通过腹膜内、新生儿灌洗管回收细胞,测定人T细胞亚群。数据为每组五只小鼠测量值的平均值+_:~。SF 162和UCI是非细胞聚集性的嗜巨噬细胞分离株,而SF 2、SF 1-和SF 33是细胞致病性增加的嗜T细胞分离株。SF 33具有极高的复制率,诱导合胞体形成,并对MT-2细胞引起细胞病变效应。病毒负荷:用定量聚合酶链反应(PCR)测定,两组间无显著性差异。用SF162或SF33感染的小鼠组中,无论是游离病毒还是感染细胞2-。IL的淋巴结也存在类似的数据:! 10~tcd hu-PBI-SCID小鼠。
Fig. 1. Depletirm of human CD4 T cells follou, ing infection of severe com-hine: l immunode/: iciency mice beari, g human peripheral hh od mommuclear cell grafts (hu-PBL-SCID) mice u, ith different strains, f HIV-I or HIV-2. The left panel shows infection with five different HIV-I c, r HIV-2 IUC1) viruses derived from molecular clones. Infection was accomplished by injection of cell-free virus. The right panel shou, sa separate experiment in u, hich hu-PBL-SCID mice were infected u'ith either cell-free virus (SF33-free and SF162-free) or 1 x lO infc'ted hu-PBLs (SF33-cell and SF162-cell). Human T-cell subsets were n, easured in cells recovered by perit, neal lavage tu,, weeks after infection. Data are the mean+ _:~ of measurements from five mice per group. SF162 and UCI are non-cytogathic, macrophage-tropic isolates, while SF2, SFI~ and SF33 are T-cell-tropic isolates of increasing cytopathicity. SF33 has an extremely high replication rate, induces syncytiu,: formation, and causes cytopathic effects on MT-2 cells. Viral burde:, in thes~ experiments was determined by quantitative polymerase chain reaction (PCR), and did not differ significantly betu, een,: m.'of the groups of mice infected with SF162 or SF33, either as free virus or infected cells 2-. Similar data exist for lymph nodes of il:!'e~ tcd hu-PBI-SCID mice.
