猫免疫缺陷病毒(FIV)感染是通过与CD 134和CXCR 4的连续相互作用介导的。病毒的田间株在它们对CD 134的富含半胱氨酸的结构域2(CRD 2)的依赖性方面有所不同。在这里,我们分析了39只自然感染猫血液中病毒变体的受体使用情况,揭示了CRD 2依赖性病毒变体在早期感染中占主导地位,随着疾病进展逐渐向CRD 2独立性发展。这些发现与CD 134使用的CRD 2随疾病进展的变化一致。本文的在线版本(doi:10.1186/s12977-014-0095-7)包含补充材料,可供授权用户使用。
Feline immunodeficiency virus (FIV) infection is mediated by sequential interactions with CD134 and CXCR4. Field strains of virus vary in their dependence on cysteine-rich domain 2 (CRD2) of CD134 for infection. Here, we analyse the receptor usage of viral variants in the blood of 39 naturally infected cats, revealing that CRD2-dependent viral variants dominate in early infection, evolving towards CRD2-independence with disease progression. These findings are consistent with a shift in CRD2 of CD134 usage with disease progression.
