[Abstract]  

Hookworms are skin penetrating parasites, however in the laboratory the hookworm model Nippostrongylus brasiliensis, the parasite is traditionally administered subcutaneously bypassing the skin (epidermis and dermis). Here, we describe two complementary approaches for infecting mice with N. brasiliensis in order to study the skin immune responses. The first approach employs a skin percutaneous injection that is poorly efficient with the laboratory strain of the parasite in mice, but represents a natural infection. The second approach employs an intradermal injection of the parasite, allowing the controlled delivery of the parasitic larvae and leads to an infection that closely mimics the natural kinetics of parasite migration and development. Both of those infection models allow the

[摘要]  [摘要]钩虫是穿透皮肤的寄生虫,但是在实验室中,钩虫模型巴西柔毛夜蛾(Nippostrongylus brasiliensis),传统上是通过皮下绕过皮肤(表皮和真皮)进行施用的。在这里,我们描述了两种互补的方法,以感染巴西猪笼草 为了研究皮肤的免疫反应。第一种方法采用皮肤经皮注射,其对小鼠体内寄生虫的实验室菌株效率较差,但代表自然感染。第二种方法是通过皮内注射寄生虫,从而控制寄生幼虫的递送,并导致感染,该感染与寄生虫迁移和发育的自然动力学密切相似。这两种感染模型均允许研究人员研究针对寄生虫的皮肤免疫反应,以及对寄生虫在皮肤入侵过程中采用的早期免疫调节策略的详细研究。


[背景]钩虫幼虫迁移从皮肤到肺部,最后才到达肠道,在那里他们完成MA turation成成虫,并开始繁殖。针对钩虫免疫每个发育阶段的过程中出现和以下的初级和次级感染(Bouchery等人。,201 7 )。W¯¯休斯特对肺和寄生虫感染的肠相位的宿主的免疫反应是公特征在于,所述皮肤反应仅被部分地特征为利用啮齿动物钩虫,当前模型日圆线虫巴西(铌),传统上经由递送感染幼虫皮下感染途径绕过了事实上的皮肤。为了解决这个问题,我们开发了两种感染方法,可以研究皮肤穿透阶段。这些模型利用感染性幼虫的皮内感染,允许递送控制剂量的寄生虫,或局部应用模仿钩虫自然皮肤渗透的幼虫(Gharib,1955)。 ...
