虽然原发HIV 1型(HIV-1)分离株的感染通常需要病毒包膜蛋白与CD4和CCR-5共受体的功能性相互作用,但这类分离株的一部分也能够使用不同的CCR-3受体。通过分析一系列野生型和嵌合HIV-1包膜蛋白介导CCR-3依赖性感染的能力,我们确定了CCR-3的趋向性映射到包膜的V1和V2可变区。尽管将CCR-3热带包膜的V1/V2区域替换为CCR-5热带包膜是赋予CCR-3向性的必要和充分条件,但当插入到CXCR-4热带HIV-1包膜环境中时,这种相同的替换没有表型效应。然而,当引入CCR-5向性V3环序列时,后者嵌合体同时获得CCR-3和CCR-5的向性。这些数据表明,包膜的V1/2区域可以像V3环区一样编码特定的辅受体需求,并表明功能性包膜:CCR-3的相互作用可能取决于CCR-3与包膜的V1/V2和V3区域的合作相互作用。
Although infection by primary HIV type 1 (HIV-1) isolates normally requires the functional interaction of the viral envelope protein with both CD4 and the CCR-5 coreceptor, a subset of such isolates also are able to use the distinct CCR-3 receptor. By analyzing the ability of a series of wild-type and chimeric HIV-1 envelope proteins to mediate CCR-3-dependent infection, we have determined that CCR-3 tropism maps to the V1 and V2 variable region of envelope. Although substitution of the V1/V2 region of a CCR-3 tropic envelope into the context of a CCR-5 tropic envelope is both necessary and sufficient to confer CCR-3 tropism, this same substitution has no phenotypic effect when inserted into a CXCR-4 tropic HIV-1 envelope context. However, this latter chimera acquires both CCR-3 and CCR-5 tropism when a CCR-5 tropic V3 loop sequence also is introduced. These data demonstrate that the V1/2 region of envelope can, like the V3 loop region, encode a particular coreceptor requirement and suggest that a functional envelope:CCR-3 interaction may depend on the cooperative interaction of CCR-3 with both the V1/V2 and the V3 region of envelope.
