has successfully developed strategies to evade host's immune response and reach immune privileged sites, which remains in a controlled environment inside quiescent tissue cysts. In this review, we will approach several known mechanisms used by the parasite to modulate mainly the murine immune system at its favor. In what follows, we review recent findings revealing interference of host's cell autonomous immunity and cell signaling, gene expression, apoptosis, and production of microbicide molecules such as nitric oxide and oxygen reactive species during parasite infection. Modulation of host's metalloproteinases of extracellular matrix is also discussed. These immune evasion strategies are determinant to parasite dissemination throughout the host taking advantage of cells from the immune system to reach brain and retina, crossing crucial hosts' barriers.
已成功开发出逃避宿主免疫反应并抵达免疫特权部位的策略,这些部位处于静止组织囊肿内的可控环境中。在本综述中,我们将探讨该寄生虫用于主要调节鼠免疫系统以使其受益的几种已知机制。接下来,我们回顾近期的研究发现,这些发现揭示了寄生虫感染期间对宿主细胞自主免疫、细胞信号传导、基因表达、细胞凋亡以及诸如一氧化氮和活性氧等杀微生物分子产生的干扰。还讨论了对宿主细胞外基质金属蛋白酶的调节。这些免疫逃避策略对于寄生虫利用免疫系统细胞在宿主体内传播以抵达大脑和视网膜、跨越宿主关键屏障起着决定性作用。
