miRNA在寄生虫与宿主协同进化中的作用

扫码查看
miRNA为非编码小RNA,通过RNA干扰的方式对基因表达进行调控。宿主和寄生虫之间的互作是一个复杂有趣,并且有特异性的协同进化过程。对于寄生虫来讲,寄生虫释放的一些miRNA为其在宿主体内繁殖起到重要作用,而一些宿主也可以通过miRNA靶向寄生虫基因,从而抵御寄生虫的入侵。miRNA参与到宿主和寄生虫体内的免疫调节、基因调控等过程,甚至可能在寄生致病机理、寄生特异性及共适应过程中发挥重要作用。研究寄生虫与宿主之间miRNA的互作,对于解析宿主抗性、寄生虫的毒性及传染性,以及协同进化过程中的平衡状态具有重要的研究意义。
The Role of miRNA During Parasite and Host Co-evolution
As a class of small non-coding RNAs,miRNAs regulate the gene expression through RNAi mechanism.The interaction between the host and parasite,interesting and specialized co-evolutionary process.For parasites,miRNAs are released to facilitate their proliferation in the hosts.As a counterpart,hosts can also resist the invasion of parasites by targeting the genes of parasites with RNAi.miRNAs are involved in immune responses and global gene expression in both hosts and parasites.miRNAs may even play an important role in pathogenesis,parasitism specificity and co-adaptation between parasites and hosts.Studying the miRNA interaction between the parasites and hosts is essential to reveal the host tolerance as well as the trade-off between parasite virulence and transmission during the co-evolutionary process.
