概括

主体遗传学会影响 Echinococcus multilocularis 寄生虫的成熟. 特定的小鼠染色体区域控制着原生的发育,揭示了破坏寄生虫传播的潜在目标.

科学领域:

寄生虫学的寄生虫学
免疫学免疫学免疫学
遗传学遗传学是一个

背景情况:

由 Echinococcus multilocularis 引起的气泡状球菌是严重的公共卫生问题.
动物是寄生虫成熟的中间宿主,对于向最终宿主传播至关重要.

研究的目的:

确定控制 Echinococcus multilocularis protoscolex 发育和成熟的宿主遗传因素.
研究宿主基因在寄生虫生命周期调节中的作用.

主要方法:

在耐药C57BL/6N背景上利用了具有易受DBA/2基因组段的先天性小鼠.
感染后16周评估了肝脏前列腺癌和与免疫相关的基因表达.

主要成果:

所有先天性菌株都发生了原始结核病,但由于染色体1上的C57BL / 6N贡献增加,成熟度下降.
确定了两个调节前细胞成熟的位置 (Empmat1和Empmat2),而不是早期发育.
观察到有限的免疫参与;T-box转录因子21表达与成熟相关,但是在识别位置之外.

结论:

前列腺细胞的成熟是由不同于早期发育的多个宿主遗传因素调节的.
C57BL/6N等位基因可能通过非免疫机制抑制成熟.
阐明这些途径可以提供新的目标来破坏寄生虫生命周期并减少动物传播.

Diversity of Protists I

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...
