摘要:

刚地弓形虫可引起人兽共患寄生虫病,弓形虫组织包囊引起的慢性感染可导致宿主神经系统功能异常,诱发宿主行为改变或精神障碍,如导致寄生动物宿主降低对捕食者的恐惧等,人类宿主的多种精神障碍也与慢性感染显著相关。目前已知介导该过程可能的机制,包括脑包囊感染、中枢神经递质失衡,以及表观遗传调控“行为操纵”等,但确切机制尚不明确。本文就刚地弓形虫感染导致宿主精神行为异常的相关研究,以及目前研究较为深入的发生机制研究进展进行综述。

Abstract:

Toxoplasma gondii can cause zoonotic parasitic diseases in humans and animals. Chronic toxoplasmosis induced by toxoplasma cysts could cause nervous system dysfunction, behavioural changes or mental disorders in the hosts, including reducing the natural fear of predators in the rodent host. Multiple psychiatric disorders in human hosts were also significantly associated with T. gondii chronic infection. The possible mechanisms that regulate this process include cerebral cyst infection, central neurotransmitter disorders, and epigenetic regulation of“behavioural manipulation”, but the precise mechanism remains unclear. In this review, we have summarized relevant studies of the host abnormal mental behaviour induced by T. gondii, and summarized the well-established mechanism(s) for this process.

Key words: Toxoplasma gondii, Brain cyst, Neurotransmitter, Behavioral manipulation, Epigenetics
