检测了具有人CD 4特异性的鼠单克隆抗体(MAb)抑制原代人免疫缺陷病毒1型(HIV-1)分离株A至E进化枝的能力。使用人外周血单核细胞(PBMC)作为感染性的靶细胞。在存在或不存在抗CD 4 MAb(指定为P1)的情况下,检查HIV-1原代分离株感染PBMC靶标的能力。P1广泛抑制进化枝A,C,D和E分离株,基于HIV-1 p24抗原浓度的降低与未经处理的对照组相比。对于主要的HIV-1进化枝B分离株(命名为BZ 167),观察到几乎没有病毒抑制活性。此外,第二初级进化枝B分离株被P1有效抑制感染PBMC靶。数据表明,P1在体外对非进化枝B原代HIV-1分离株表现出组特异性抑制活性。
A murine monoclonal antibody (MAb) with human CD4 specificity was tested for the ability to inhibit primary human immunodeficiency virus type 1 (HIV-1) isolates clades A through E. Human peripheral blood mononuclear cells (PBMC) were used as target cells for infectivity. The HIV-1 primary isolates were examined for the capacity to infect PBMC targets in the presence or absence of the anti-CD4 MAb, designated P1. P1 broadly inhibited clade A, C, D, and E isolates, based on a reduction of HIV-1 p24 antigen concentrations compared with untreated controls. Little to no virus-inhibiting activity was observed with a primary HIV-1 clade B isolate, designated BZ167. Additionally, a second primary clade B isolate was efficiently inhibited from infecting PBMC targets by P1. The data indicate that P1 exhibits group-specific inhibiting activity against non-clade B primary HIV-1 isolates in vitro.
