最近已经证明,D型猿猴逆转录病毒的两种血清型,即SRV-1和SRV-2,表现出广泛的免疫交叉反应性,但在中和抗体水平上不表现出交叉反应性。我们最近还表明,包括SRV-1包膜蛋白残基147-162的区域构成抗SRV-1但不抗SRV-2的中和抗体所针对的表位。然而,尽管各种免疫原性制剂能够诱导与SRV-1反应的抗体,但这些抗体不能中和体外病毒感染性。本文报道的工作表明,由较大肽(即,SRV-1包膜蛋白的142-167)组成的各种免疫原诱导能够与SRV-1包膜蛋白和整个病毒结合的抗体。此外,这些抗体表现出体外中和SRV-1的感染性而不是SRV-2的感染性的能力。
It has been recently demonstrated that two serotypes of type D simian retroviruses, namely SRV-1 and SRV-2, exhibit extensive immunological cross-reactivity but do not exhibit cross-reactivity at the level of neutralizing antibodies. We have also shown recently that an area which includes residues 147–162 of the envelope protein of SRV-1 constitutes an epitope to which neutralizing antibodies against SRV-1 but not against SRV-2 are directed. However, in spite of the capacity of various immunogenic preparations to induce antibodies which react with SRV-1 these antibodies were incapable of neutralizingin vitroviral infectivity.Work reported herein demonstrates that various immunogens consisting of a larger peptide, namely 142–167 of the envelope protein of SRV-1, induce antibodies capable of binding with the envelope protein of SRV-1 and with the whole virus. Moreover, these antibodies exhibit the capacity to neutralizein vitrothe infectivity of SRV-1 but not of SRV-2.
