摘要:

弓形虫是一种专性寄生于细胞内的顶复门原虫,具有多宿主、多阶段的发育周期。弓形虫有性阶段仅限于猫科动物,而无性阶段发生在包括人类在内的大多数温血动物中。全世界大约有三分之一的人感染弓形虫病,同时该病也能够对畜牧业造成严重经济损失。刚地弓形虫具有一套复杂的基因调控网络,能够使虫体在适应不同的外界环境变化时及时在特定的阶段进行自身基因的转录及表达。然而,目前人们对其潜在的转录调控机制知之甚少。研究发现特异性的转录因子(transcription factors, TFs)在真核生物的转录调控中具有重要作用,特别是AP2(apetala 2, AP2)家族转录因子参与了弓形虫不同阶段基因表达过程,这些因子在寄生虫生长和发育过程中发挥极其重要的作用。本文结合近几年的研究成果,对弓形虫转录因子AP2家族蛋白质的研究进展进行汇总,以期为深入研究弓形虫的生物学特征奠定基础。

Abstract:

Toxoplasma gondii is an obligate intracellular parasitic protozoan belonging to the phylum Apicomplexa, with a complex life cycle involving multiple hosts and stages. T. gondii has a sexual stage restricted to felid species, while the asexual stage occurs in most warm-blooded animals including humans. About one-third of the world's population is infected with toxoplasmosis, and it can also cause serious economic losses in the livestock industry. T. gondii has a sophisticated gene regulatory network that enables it to timely transcribe its own genes as it adapts to changes in the external environment during specific stages. However, little is known about its potential transcriptional regulatory mechanisms. It has been found that specific transcription factors (TFs) play an important role in eukaryotic transcriptional regulation, especially the apetala 2 (AP2) family of transcription factors, which are involved in T. gondii gene expression during different stages. These factors play a crucial role in the growth and development of parasites. This article reviews the research progress of the Apicomplexan AP2 (ApiAP2) family of proteins in T. gondii, combining recent research results, in order to lay a foundation for further study of the biological characteristics of T. gondii.

Key words: Toxoplasma gondii, specific transcription factors, gene, cyst
