Foamy virus evolution closely parallels that of the host species, indicating virus-host coadaptation. We studied simian foamy viruses (SFVs) from common marmosets, spider monkeys, and squirrel monkeys, New World monkey (NWM) species that share geographic ranges. The TRIM5alpha protein from each of these NWM species inhibited the replication of at least one of the SFVs associated with the other two species but did not affect the replication of its own SFV. Thus, TRIM5alpha has potentially shaped the evolution of SFVs in NWM hosts. Conversely, SFVs may have influenced the evolution of TRIM5 variants in New World primates.
泡沫病毒的进化与宿主物种密切相关,表明病毒与宿主的共同适应。我们研究了来自普通狨猴、蜘蛛猴和松鼠猴的猴泡沫病毒(SFV),这些是在地理分布上有重叠的新世界猴(NWM)物种。这些 NWM 物种的 TRIM5alpha 蛋白都能抑制与其他两种物种相关的至少一种 SFV 的复制,但不影响其自身 SFV 的复制。因此,TRIM5alpha 可能已经塑造了 NWM 宿主中 SFV 的进化。相反,SFV 可能影响了新世界灵长类动物中 TRIM5 变体的进化。
