简介：HIV-1p24察觉提供一个工具帮助HIV-1感染的早诊断，追踪疾病的前进并且估计antiretroviral治疗的功效。在对HIV-1的现在的学习，三monoclonal抗体(mAbs)p3JB9，p5F1和p6F4，p24被产生。所有mAbs能检测HIV-1B，HIV-1Ada-M，HIV-174vmAbsp5F1和p6F4的p24能检测HIV-1KM018，当p3JB9不能时。三mAbs没与HIV-2ROD，HIV-2CBL-20和SIVagmTyo-1反应。p5F1的公认的epitope位于Gag氨基酸区域DCKTILKALGPAATLEEMMTAC。p5F1被用来与兔子anti-p24浆液建立修改三明治ELISA并且显示出好特性和高敏感，它被用来在研究测量HIV-1p24抗原层次。

简介：临床的试用和动物实验的增加的数字显示出细菌为过敏症预防正在答应工具的那probiotic。这里，我们在过敏促进感受性上分析了三选择乳杆菌紧张的immunomodulatory性质和他们的混合的影响赌1用一只gnotobiotic老鼠建模的v。我们显示出那乳杆菌(L.)rhamnosusLOCK0900，L。rhamnosusLOCK0908和L。caseiLOCK0919经由像使用费的受体被认出2(TLR2)并且核苷酸绑定oligomerization包含域的蛋白质2(NOD2)受体并且刺激骨头在种类依赖者和紧张依赖者礼貌生产cytokines的导出髓的树枝状的房间。殖民无菌(GF)有所有三紧张(Lmix)的混合物的鼠标由加强enterocytes的顶端的junctional建筑群并且恢复延续到终端网的微细丝的结构改进了肠的障碍。与Lmix开拓殖民地于并且敏化1变应原到赌注v的老鼠显著地象一个增加的转变生长因素(TGF)一样在sera和肠的lavages显示出变应原特定的IgE，IgG1和IgG2a和提高的全部的IgA水平的底层-β；与敏化的GF老鼠相比铺平。从开拓殖民地于Lmix的老鼠的Splenocytes和mesenteric淋巴节点房间显示出TGF-β的重要upregulation；在以后在有赌注v的vitro刺激1。我们的结果证明Lmix殖民改进了内脏对赌注v的上皮的障碍和减少的过敏促进感受性1。而且，这些调查结果被传播和能分泌的IgA和规章的cytokineTGF-β的增加的生产伴随；。因此，三乳杆菌紧张的这混合物在人在增加的内脏渗透和过敏症的发作的预防为使用显示出潜力。
