[Abstract]  To cause an infection, the human specific pathogen Neisseria meningitides must first colonize the nasopharynx. Upon tight interaction with the mucosal epithelium, N. meningitidis may cross the epithelial cellular barrier, reach the bloodstream and cause sepsis and/or meningitis. Since N. meningitidis niche is restricted to humans the availability of relevant animal models to study host-pathogen interactions are limiting. Therefore, most findings that involve N. meningitidis colonization derive from studies using cultured human cell lines. Human epithelial cells have been successfully used to examine and identify molecular effectors involved in initial adherence of the pathogen. Here, we describe a standard protocol to quantify the adherence of N. ... [摘要]  为了引起感染,人类特定的病原体脑膜炎奈瑟氏脑必须首先在鼻咽中定居。 与粘膜上皮紧密相互作用时, 脑膜炎双球菌可能穿过上皮细胞屏障,到达血流并引起败血症和/或脑膜炎。 由于 N meningitidis niche限于人类。 因此,大多数涉及N 脑膜炎菌群定植来源于使用培养的人类细胞系的研究。 在最初的病原体坚持。 在这里,我们描述了一个标准协议来量化N的遵守情况。 脑膜炎双球菌对上皮细胞FaDu细胞的作用。 感染后收集的细胞裂解物的集落计数用于量化对上皮细胞的粘附。

【背景】作为细菌发病机制的重要一步。细菌粘附素与宿主细胞表面受体之间的分子相互作用决定了定植位点(Soto and Hultgren,1999)。鼻咽中的上皮层形成人类限制性病原体N的第一个细胞屏障。 meningitidis 遇到和无症状殖民。牢固粘附,并与宿主细胞相互作用可导致上皮细胞和进入血液的渗透,在危及生命的败血症和/或脑膜炎(斯蒂芬斯,2009)得到的。从细菌膜延伸出来的长细丝(称为IV型菌毛(Tfp))与PilC1尖端定位的粘附素在初始依从性中起关键作用。脑膜炎到鼻咽上皮细胞(Marceau等,1995; Rudel等,1995)。 Tfp不仅促进与宿主细胞的相互作用,而且参与细菌聚集体的发育,这可以有助于高水平的粘附和抵抗剪切应力(Helaine等,2005,Mikaty ...

[Abstract]  Atherosclerosis is a chronic inflammatory disease of the arterial wall characterized by lipid deposition, plaque formation, and immune cell infiltration. Innate and adaptive immune cells infiltrate the artery during development of the disease. Moreover, advanced disease leads to formation of artery tertiary lymphoid organs in the adventitia (Grabner et al., 2009; Hu et al., 2015). Various and diverse types of immune cells have been identified in the aorta adventitia vs atherosclerotic plaques (Elewa et al., 2016; Galkina et al., 2006; Lotzer et al., 2010; Mohanta et al., 2016; Mohanta et al., 2014; Moos et al., 2005; Srikakulapu et al., 2016; Zhao et al., 2004). There are conflicting reports on the number and subtypes ... [摘要]  动脉粥样硬化是动脉壁的慢性炎性疾病,其特征在于脂质沉积,斑块形成和免疫细胞浸润。先天性和适应性免疫细胞在疾病发展期间浸润动脉。此外,晚期疾病导致外膜中动脉三级淋巴器官的形成(Grabner等人,2009; Hu等人,2015)。已经在主动脉外膜vs动脉粥样硬化斑块中鉴定了各种不同类型的免疫细胞(Elewa等人,2016; Galkina等人,2006; Lotzer等人, 2010; Mohanta等人,2016; Mohanta等人,2014; Moos等人,2010; Mohanta等人,2010; 2005; Srikakulapu et al。,2016; Zhao et al。,2004)。根据动物的年龄,用于获得单细胞悬浮液的方案和小鼠的饮食条件,存在关于主动脉中免疫细胞的数量和亚型的矛盾报告(Campbell等, 2012; Clement等人,2015; Galkina等人,2006; Kyaw等人,2012)。使用不同的方案,主动脉中免疫细胞的数目差异多达十倍(Butcher等,2012; Galkina等,2006; Gjurich等,2015; Grabner等人,2009; ...
